TextView

public class TextView
extends View implements ViewTreeObserver.OnPreDrawListener

java.lang.Object
   ↳ android.view.View
     ↳ android.widget.TextView

A user interface element that displays text to the user. To provide user-editable text, see EditText.

The following code sample shows a typical use, with an XML layout and code to modify the contents of the text view: 

 <LinearLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent">
    <TextView
        android:id="@+id/text_view_id"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="@string/hello" />
 </LinearLayout>

This code sample demonstrates how to modify the contents of the text view defined in the previous XML layout: 

 public class MainActivity extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         final TextView helloTextView = (TextView) findViewById(R.id.text_view_id);
         helloTextView.setText(R.string.user_greeting);
     }
 }

Related methods:

android:imeOptions

Additional features you can enable in an IME associated with an editor to improve the integration with your application. The constants here correspond to those defined by EditorInfo.imeOptions.

Must be one or more (separated by '|') of the following constant values.

ConstantValueDescription
actionDone6The action key performs a "done" operation, closing the soft input method. Corresponds to EditorInfo.IME_ACTION_DONE.
actionGo2The action key performs a "go" operation to take the user to the target of the text they typed. Typically used, for example, when entering a URL. Corresponds to EditorInfo.IME_ACTION_GO.
actionNext5The action key performs a "next" operation, taking the user to the next field that will accept text. Corresponds to EditorInfo.IME_ACTION_NEXT.
actionNone1This editor has no action associated with it. Corresponds to EditorInfo.IME_ACTION_NONE.
actionPrevious7The action key performs a "previous" operation, taking the user to the previous field that will accept text. Corresponds to EditorInfo.IME_ACTION_PREVIOUS.
actionSearch3The action key performs a "search" operation, taking the user to the results of searching for the text the have typed (in whatever context is appropriate). Corresponds to EditorInfo.IME_ACTION_SEARCH.
actionSend4The action key performs a "send" operation, delivering the text to its target. This is typically used when composing a message. Corresponds to EditorInfo.IME_ACTION_SEND.
actionUnspecified0There is no specific action associated with this editor, let the editor come up with its own if it can. Corresponds to EditorInfo.IME_NULL.
flagForceAscii80000000Used to request that the IME should be capable of inputting ASCII characters. The intention of this flag is to ensure that the user can type Roman alphabet characters in a TextView used for, typically, account ID or password input. It is expected that IMEs normally are able to input ASCII even without being told so (such IMEs already respect this flag in a sense), but there could be some cases they aren't when, for instance, only non-ASCII input languages like Arabic, Greek, Hebrew, Russian are enabled in the IME. Applications need to be aware that the flag is not a guarantee, and not all IMEs will respect it. However, it is strongly recommended for IME authors to respect this flag especially when their IME could end up with a state that has only non-ASCII input languages enabled.

Corresponds to EditorInfo.IME_FLAG_FORCE_ASCII.

flagNavigateNext8000000Used to specify that there is something interesting that a forward navigation can focus on. This is like using actionNext, except allows the IME to be multiline (with an enter key) as well as provide forward navigation. Note that some IMEs may not be able to do this, especially when running on a small screen where there is little space. In that case it does not need to present a UI for this option. Like actionNext, if the user selects the IME's facility to forward navigate, this will show up in the application at InputConnection.performEditorAction(int).

Corresponds to EditorInfo.IME_FLAG_NAVIGATE_NEXT.

flagNavigatePrevious4000000Like flagNavigateNext, but specifies there is something interesting that a backward navigation can focus on. If the user selects the IME's facility to backward navigate, this will show up in the application as an actionPrevious at InputConnection.performEditorAction(int).

Corresponds to EditorInfo.IME_FLAG_NAVIGATE_PREVIOUS.

flagNoAccessoryAction20000000Used in conjunction with a custom action, this indicates that the action should not be available as an accessory button when the input method is full-screen. Note that by setting this flag, there can be cases where the action is simply never available to the user. Setting this generally means that you think showing text being edited is more important than the action you have supplied.

Corresponds to EditorInfo.IME_FLAG_NO_ACCESSORY_ACTION.

flagNoEnterAction40000000Used in conjunction with a custom action, this indicates that the action should not be available in-line as a replacement for the "enter" key. Typically this is because the action has such a significant impact or is not recoverable enough that accidentally hitting it should be avoided, such as sending a message. Note that TextView will automatically set this flag for you on multi-line text views.

Corresponds to EditorInfo.IME_FLAG_NO_ENTER_ACTION.

flagNoExtractUi10000000Used to specify that the IME does not need to show its extracted text UI. For input methods that may be fullscreen, often when in landscape mode, this allows them to be smaller and let part of the application be shown behind. Though there will likely be limited access to the application available from the user, it can make the experience of a (mostly) fullscreen IME less jarring. Note that when this flag is specified the IME may not be set up to be able to display text, so it should only be used in situations where this is not needed.

Corresponds to EditorInfo.IME_FLAG_NO_EXTRACT_UI.

flagNoFullscreen2000000Used to request that the IME never go into fullscreen mode. Applications need to be aware that the flag is not a guarantee, and not all IMEs will respect it.

Corresponds to EditorInfo.IME_FLAG_NO_FULLSCREEN.

flagNoPersonalizedLearning1000000Used to request that the IME should not update any personalized data such as typing history and personalized language model based on what the user typed on this text editing object. Typical use cases are:
  • When the application is in a special mode, where user's activities are expected to be not recorded in the application's history. Some web browsers and chat applications may have this kind of modes.
  • When storing typing history does not make much sense. Specifying this flag in typing games may help to avoid typing history from being filled up with words that the user is less likely to type in their daily life. Another example is that when the application already knows that the expected input is not a valid word (e.g. a promotion code that is not a valid word in any natural language).

Applications need to be aware that the flag is not a guarantee, and some IMEs may not respect it.

normal0There are no special semantics associated with this editor.

Public methods

addExtraDataToAccessibilityNodeInfo

Added in API level 26 
public void addExtraDataToAccessibilityNodeInfo (AccessibilityNodeInfo info, 
                String extraDataKey, 
                Bundle arguments)

Adds extra data to an AccessibilityNodeInfo based on an explicit request for the additional data.

This method only needs overloading if the node is marked as having extra data available.

Parameters
info AccessibilityNodeInfo: The info to which to add the extra data. Never null.
extraDataKey String: A key specifying the type of extra data to add to the info. The extra data should be added to the Bundle returned by the info's AccessibilityNodeInfo#getExtras method. Never null.
arguments Bundle: A Bundle holding any arguments relevant for this request. May be null if the service provided no arguments.

addTextChangedListener

Added in API level 1 
public void addTextChangedListener (TextWatcher watcher)

Adds a TextWatcher to the list of those whose methods are called whenever this TextView's text changes.

In 1.0, the TextWatcher#afterTextChanged method was erroneously not called after setText(char, int, int) calls. Now, doing setText(char, int, int) if there are any text changed listeners forces the buffer type to Editable if it would not otherwise be and does call this method.

Parameters
watcher TextWatcher

append

Added in API level 1 
public final void append (CharSequence text)

Convenience method to append the specified text to the TextView's display buffer, upgrading it to TextView.BufferType.EDITABLE if it was not already editable.

Parameters
text CharSequence: text to be appended to the already displayed text

append

Added in API level 1 
public void append (CharSequence text, 
                int start, 
                int end)

Convenience method to append the specified text slice to the TextView's display buffer, upgrading it to TextView.BufferType.EDITABLE if it was not already editable.

Parameters
text CharSequence: text to be appended to the already displayed text
start int: the index of the first character in the text
end int: the index of the character following the last character in the text

autofill

Added in API level 26 
public void autofill (AutofillValue value)

Automatically fills the content of this view with the value.

Views support the Autofill Framework mainly by:

  • Providing the metadata defining what the view means and how it can be autofilled.
  • Implementing the methods that autofill the view.

onProvideAutofillStructure(android.view.ViewStructure, int) is responsible for the former, this method is responsible for latter.

This method does nothing by default, but when overridden it typically:

  1. Checks if the provided value matches the expected type (which is defined by getAutofillType()).
  2. Checks if the view is editable - if it isn't, it should return right away.
  3. Call the proper getter method on AutofillValue to fetch the actual value.
  4. Pass the actual value to the equivalent setter in the view.

For example, a text-field view could implement the method this way: 

 @Override
 public void autofill(AutofillValue value) {
   if (!value.isText() || !this.isEditable()) {
      return;
   }
   CharSequence text = value.getTextValue();
   if (text != null) {
     this.setText(text);
   }
 }

If the value is updated asynchronously, the next call to AutofillManager#notifyValueChanged(View) must happen after the value was changed to the autofilled value. If not, the view will not be considered autofilled.

Note: After this method is called, the value returned by getAutofillValue() must be equal to the value passed to it, otherwise the view will not be highlighted as autofilled.

Parameters
value AutofillValue: value to be autofilled.

beginBatchEdit

Added in API level 3 
public void beginBatchEdit ()

bringPointIntoView

getUseBoundsForWidth

Added in API level 35 
public boolean getUseBoundsForWidth ()

Returns true if using bounding box as a width, false for using advance as a width.

Returns
boolean True if using bounding box for width, false if using advance for width.

hasOverlappingRendering

Added in API level 16 
public boolean hasOverlappingRendering ()

Returns whether this View has content which overlaps.

This function, intended to be overridden by specific View types, is an optimization when alpha is set on a view. If rendering overlaps in a view with alpha < 1, that view is drawn to an offscreen buffer and then composited into place, which can be expensive. If the view has no overlapping rendering, the view can draw each primitive with the appropriate alpha value directly. An example of overlapping rendering is a TextView with a background image, such as a Button. An example of non-overlapping rendering is a TextView with no background, or an ImageView with only the foreground image. The default implementation returns true; subclasses should override if they have cases which can be optimized.

Note: The return value of this method is ignored if forceHasOverlappingRendering(boolean) has been called on this view.

Returns
boolean true if the content in this view might overlap, false otherwise.

hasSelection

Added in API level 1 
public boolean hasSelection ()

Return true iff there is a selection of nonzero length inside this text view.

Returns
boolean

Returns
boolean

isCursorVisible

Added in API level 16 
public boolean isCursorVisible ()

Related XML Attributes:

Returns
boolean whether or not the cursor is visible (assuming this TextView is editable). This method may return false when the IME is consuming the input even if the mEditor.mCursorVisible attribute is true or #setCursorVisible(true) is called.

isElegantTextHeight

Added in API level 28 
public boolean isElegantTextHeight ()

Get the value of the TextView's elegant height metrics flag. This setting selects font variants that have not been compacted to fit Latin-based vertical metrics, and also increases top and bottom bounds to provide more space.

Returns
boolean true if the elegant height metrics flag is set.

isFallbackLineSpacing

Added in API level 28 
public boolean isFallbackLineSpacing ()

Related XML Attributes:

Returns
boolean whether fallback line spacing is enabled, true by default

isHorizontallyScrollable

Added in API level 29 
public final boolean isHorizontallyScrollable ()

Returns whether the text is allowed to be wider than the View. If false, the text will be wrapped to the width of the View.

Related XML Attributes:

Returns
boolean

isInputMethodTarget

Added in API level 3 
public boolean isInputMethodTarget ()

Returns whether this text view is a current input method target. The default implementation just checks with InputMethodManager.

Returns
boolean True if the TextView is a current input method target; false otherwise.

isLocalePreferredLineHeightForMinimumUsed

Added in API level 35 
public boolean isLocalePreferredLineHeightForMinimumUsed ()

Returns true if the locale preferred line height is used for the minimum line height.

Returns
boolean true if using locale preferred line height for the minimum line height. Otherwise false.

Related XML Attributes:

Returns
boolean

isSuggestionsEnabled

Added in API level 14 
public boolean isSuggestionsEnabled ()

Return whether or not suggestions are enabled on this TextView. The suggestions are generated by the IME or by the spell checker as the user types. This is done by adding SuggestionSpans to the text. When suggestions are enabled (default), this list of suggestions will be displayed when the user asks for them on these parts of the text. This value depends on the inputType of this TextView. The class of the input type must be InputType#TYPE_CLASS_TEXT. In addition, the type variation must be one of InputType#TYPE_TEXT_VARIATION_NORMAL, InputType#TYPE_TEXT_VARIATION_EMAIL_SUBJECT, InputType#TYPE_TEXT_VARIATION_LONG_MESSAGE, InputType#TYPE_TEXT_VARIATION_SHORT_MESSAGE or InputType#TYPE_TEXT_VARIATION_WEB_EDIT_TEXT. And finally, the InputType#TYPE_TEXT_FLAG_NO_SUGGESTIONS flag must not be set.

Returns
boolean true if the suggestions popup window is enabled, based on the inputType.

isTextSelectable

Added in API level 11 
public boolean isTextSelectable ()

Returns the state of the textIsSelectable flag (See setTextIsSelectable()). Although you have to set this flag to allow users to select and copy text in a non-editable TextView, the content of an EditText can always be selected, independently of the value of this flag.

Related XML Attributes:

Returns
boolean True if the text displayed in this TextView can be selected by the user.

jumpDrawablesToCurrentState

Added in API level 11 
public void jumpDrawablesToCurrentState ()

Call Drawable.jumpToCurrentState() on all Drawable objects associated with this view.

Also calls StateListAnimator#jumpToCurrentState() if there is a StateListAnimator attached to this view.
If you override this method you must call through to the superclass implementation.

length

Added in API level 1 
public int length ()

Returns the length, in characters, of the text managed by this TextView

Returns
int The length of the text managed by the TextView in characters.

moveCursorToVisibleOffset

Added in API level 3 
public boolean moveCursorToVisibleOffset ()

Move the cursor, if needed, so that it is at an offset that is visible to the user. This will not move the cursor if it represents more than one character (a selection range). This will only work if the TextView contains spannable text; otherwise it will do nothing.

Returns
boolean True if the cursor was actually moved, false otherwise.

onBeginBatchEdit

Added in API level 3 
public void onBeginBatchEdit ()

Called by the framework in response to a request to begin a batch of edit operations through a call to link beginBatchEdit().

onCheckIsTextEditor

Added in API level 3 
public boolean onCheckIsTextEditor ()

Check whether the called view is a text editor, in which case it would make sense to automatically display a soft input window for it. Subclasses should override this if they implement onCreateInputConnection(android.view.inputmethod.EditorInfo) to return true if a call on that method would return a non-null InputConnection, and they are really a first-class editor that the user would normally start typing on when the go into a window containing your view.

The default implementation always returns false. This does not mean that its onCreateInputConnection(android.view.inputmethod.EditorInfo) will not be called or the user can not otherwise perform edits on your view; it is just a hint to the system that this is not the primary purpose of this view.

Returns
boolean Returns true if this view is a text editor, else false.

onCommitCompletion

Added in API level 3 
public void onCommitCompletion (CompletionInfo text)

Called by the framework in response to a text completion from the current input method, provided by it calling InputConnection.commitCompletion(). The default implementation does nothing; text views that are supporting auto-completion should override this to do their desired behavior.

Parameters
text CompletionInfo: The auto complete text the user has selected.

onCommitCorrection

Added in API level 11 
public void onCommitCorrection (CorrectionInfo info)

Called by the framework in response to a text auto-correction (such as fixing a typo using a dictionary) from the current input method, provided by it calling InputConnection.commitCorrection(). The default implementation flashes the background of the corrected word to provide feedback to the user.

Parameters
info CorrectionInfo: The auto correct info about the text that was corrected.

onCreateInputConnection

Added in API level 3 
public InputConnection onCreateInputConnection (EditorInfo outAttrs)

Create a new InputConnection for an InputMethod to interact with the view. The default implementation returns null, since it doesn't support input methods. You can override this to implement such support. This is only needed for views that take focus and text input.

When implementing this, you probably also want to implement onCheckIsTextEditor() to indicate you will return a non-null InputConnection.

Also, take good care to fill in the EditorInfo object correctly and in its entirety, so that the connected IME can rely on its values. For example, EditorInfo.initialSelStart and EditorInfo.initialSelEnd members must be filled in with the correct cursor position for IMEs to work correctly with your application.

Parameters
outAttrs EditorInfo: Fill in with attribute information about the connection.
Returns
InputConnection

onCreateViewTranslationRequest

Added in API level 31 
public void onCreateViewTranslationRequest (int[] supportedFormats, 
                Consumer<ViewTranslationRequest> requestsCollector)

Collects a ViewTranslationRequest which represents the content to be translated in the view.

NOTE: When overriding the method, it should not collect a request to translate this TextView if it is displaying a password.

Parameters
supportedFormats int: the supported translation format. The value could be TranslationSpec.DATA_FORMAT_TEXT. This value cannot be null.
requestsCollector Consumer: Consumer to receiver the ViewTranslationRequest which contains the information to be translated. This value cannot be null.

onDragEvent

Added in API level 11 
public boolean onDragEvent (DragEvent event)

Handles drag events sent by the system following a call to startDragAndDrop().

If this text view is not editable, delegates to the default View#onDragEvent implementation.

If this text view is editable, accepts all drag actions (returns true for an ACTION_DRAG_STARTED event and all subsequent drag events). While the drag is in progress, updates the cursor position to follow the touch location. Once a drop event is received, handles content insertion via View.performReceiveContent(ContentInfo).

Parameters
event DragEvent: The DragEvent sent by the system. The DragEvent.getAction() method returns an action type constant defined in DragEvent, indicating the type of drag event represented by this object.
Returns
boolean Returns true if this text view is editable and delegates to super otherwise. See View#onDragEvent.

onEditorAction

Added in API level 3 
public void onEditorAction (int actionCode)

Called when an attached input method calls InputConnection.performEditorAction() for this text view. The default implementation will call your action listener supplied to setOnEditorActionListener(OnEditorActionListener), or perform a standard operation for EditorInfo.IME_ACTION_NEXT, EditorInfo.IME_ACTION_PREVIOUS, or EditorInfo.IME_ACTION_DONE.

For backwards compatibility, if no IME options have been set and the text view would not normally advance focus on enter, then the NEXT and DONE actions received here will be turned into an enter key down/up pair to go through the normal key handling.

Parameters
actionCode int: The code of the action being performed.

onEndBatchEdit

Added in API level 3 
public void onEndBatchEdit ()

Called by the framework in response to a request to end a batch of edit operations through a call to link endBatchEdit().

onGenericMotionEvent

Added in API level 12 
public boolean onGenericMotionEvent (MotionEvent event)

Implement this method to handle generic motion events.

Generic motion events describe joystick movements, hover events from mouse or stylus devices, trackpad touches, scroll wheel movements and other motion events not handled by onTouchEvent(android.view.MotionEvent) or onTrackballEvent(android.view.MotionEvent). The source of the motion event specifies the class of input that was received. Implementations of this method must examine the bits in the source before processing the event. The following code example shows how this is done.

Generic motion events with source class InputDevice#SOURCE_CLASS_POINTER are delivered to the view under the pointer. All other generic motion events are delivered to the focused view. 

 public boolean onGenericMotionEvent(MotionEvent event) {
     if (event.isFromSource(InputDevice.SOURCE_CLASS_JOYSTICK)) {
         if (event.getAction() == MotionEvent.ACTION_MOVE) {
             // process the joystick movement...
             return true;
         }
     }
     if (event.isFromSource(InputDevice.SOURCE_CLASS_POINTER)) {
         switch (event.getAction()) {
             case MotionEvent.ACTION_HOVER_MOVE:
                 // process the hover movement...
                 return true;
             case MotionEvent.ACTION_SCROLL:
                 // process the scroll wheel movement...
                 return true;
         }
     }
     return super.onGenericMotionEvent(event);
 }

Parameters
event MotionEvent: The generic motion event being processed.
Returns
boolean True if the event was handled, false otherwise.

onKeyDown

Added in API level 1 
public boolean onKeyDown (int keyCode, 
                KeyEvent event)

Default implementation of KeyEvent.Callback.onKeyDown(): perform press of the view when KeyEvent#KEYCODE_DPAD_CENTER or KeyEvent#KEYCODE_ENTER is released, if the view is enabled and clickable.

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters
keyCode int: a key code that represents the button pressed, from KeyEvent
event KeyEvent: the KeyEvent object that defines the button action
Returns
boolean If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

onKeyMultiple

Added in API level 1 
public boolean onKeyMultiple (int keyCode, 
                int repeatCount, 
                KeyEvent event)

Default implementation of KeyEvent.Callback.onKeyMultiple(): always returns false (doesn't handle the event).

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters
keyCode int: A key code that represents the button pressed, from KeyEvent.
repeatCount int: The number of times the action was made.
event KeyEvent: The KeyEvent object that defines the button action.
Returns
boolean If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

onKeyPreIme

Added in API level 3 
public boolean onKeyPreIme (int keyCode, 
                KeyEvent event)

Handle a key event before it is processed by any input method associated with the view hierarchy. This can be used to intercept key events in special situations before the IME consumes them; a typical example would be handling the BACK key to update the application's UI instead of allowing the IME to see it and close itself. Due to a bug, this function is not called for BACK key events on Android T and U, when the IME is shown.

Parameters
keyCode int: The value in event.getKeyCode().
event KeyEvent: Description of the key event.
Returns
boolean If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

onKeyShortcut

Added in API level 1 
public boolean onKeyShortcut (int keyCode, 
                KeyEvent event)

Called on the focused view when a key shortcut event is not handled. Override this method to implement local key shortcuts for the View. Key shortcuts can also be implemented by setting the shortcut property of menu items.

Parameters
keyCode int: The value in event.getKeyCode().
event KeyEvent: Description of the key event.
Returns
boolean If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

onKeyUp

Added in API level 1 
public boolean onKeyUp (int keyCode, 
                KeyEvent event)

Default implementation of KeyEvent.Callback.onKeyUp(): perform clicking of the view when KeyEvent#KEYCODE_DPAD_CENTER, KeyEvent#KEYCODE_ENTER or KeyEvent#KEYCODE_SPACE is released.

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters
keyCode int: A key code that represents the button pressed, from KeyEvent.
event KeyEvent: The KeyEvent object that defines the button action.
Returns
boolean If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

onPreDraw

Added in API level 1 
public boolean onPreDraw ()

Callback method to be invoked when the view tree is about to be drawn. At this point, all views in the tree have been measured and given a frame. Clients can use this to adjust their scroll bounds or even to request a new layout before drawing occurs.

Returns
boolean Return true to proceed with the current drawing pass, or false to cancel.

onPrivateIMECommand

Added in API level 3 
public boolean onPrivateIMECommand (String action, 
                Bundle data)

Called by the framework in response to a private command from the current method, provided by it calling InputConnection.performPrivateCommand().

Parameters
action String: The action name of the command.
data Bundle: Any additional data for the command. This may be null.
Returns
boolean Return true if you handled the command, else false.

onReceiveContent

Added in API level 31 
public ContentInfo onReceiveContent (ContentInfo payload)

Default TextView implementation for receiving content. Apps wishing to provide custom behavior should configure a listener via View.setOnReceiveContentListener(String, OnReceiveContentListener).

For non-editable TextViews the default behavior is a no-op (returns the passed-in content without acting on it).

For editable TextViews the default behavior is to insert text into the view, coercing non-text content to text as needed. The MIME types "text/plain" and "text/html" have well-defined behavior for this, while other MIME types have reasonable fallback behavior (see ClipData.Item#coerceToStyledText).

Parameters
payload ContentInfo: The content to insert and related metadata. This value cannot be null.
Returns
ContentInfo The portion of the passed-in content that was not handled (may be all, some, or none of the passed-in content). This value may be null.

onResolvePointerIcon

Added in API level 24 
public PointerIcon onResolvePointerIcon (MotionEvent event, 
                int pointerIndex)

Resolve the pointer icon that should be used for specified pointer in the motion event. The default implementation will resolve the pointer icon to one set using setPointerIcon(android.view.PointerIcon) for mouse devices. Subclasses may override this to customize the icon for the given pointer. For example, the pointer icon for a stylus pointer can be resolved in the following way: 

 @Override
 public PointerIcon onResolvePointerIcon(MotionEvent event, int pointerIndex) {
     final int toolType = event.getToolType(pointerIndex);
     if (!event.isFromSource(InputDevice.SOURCE_MOUSE)
             && event.isFromSource(InputDevice.SOURCE_STYLUS)
             && (toolType == MotionEvent.TOOL_TYPE_STYLUS
                     || toolType == MotionEvent.TOOL_TYPE_ERASER)) {
         // Show this pointer icon only if this pointer is a stylus.
         return PointerIcon.getSystemIcon(mContext, PointerIcon.TYPE_WAIT);
     }
     // Use the default logic for determining the pointer icon for other non-stylus pointers,
     // like for the mouse cursor.
     return super.onResolvePointerIcon(event, pointerIndex);
 }

Parameters
event MotionEvent: The MotionEvent that requires a pointer icon to be resolved for one of pointers.
pointerIndex int: The index of the pointer in event for which to retrieve the PointerIcon. This will be between 0 and MotionEvent#getPointerCount().
Returns
PointerIcon the pointer icon to use for specified pointer, or null if a pointer icon is not specified and the default icon should be used.

onRestoreInstanceState

Added in API level 1 
public void onRestoreInstanceState (Parcelable state)

Hook allowing a view to re-apply a representation of its internal state that had previously been generated by onSaveInstanceState(). This function will never be called with a null state.
If you override this method you must call through to the superclass implementation.

Parameters
state Parcelable: The frozen state that had previously been returned by onSaveInstanceState().

onRtlPropertiesChanged

Added in API level 17 
public void onRtlPropertiesChanged (int layoutDirection)

Called when any RTL property (layout direction or text direction or text alignment) has been changed. Subclasses need to override this method to take care of cached information that depends on the resolved layout direction, or to inform child views that inherit their layout direction. The default implementation does nothing.

Parameters
layoutDirection int: the direction of the layout Value is View.LAYOUT_DIRECTION_LTR, or View.LAYOUT_DIRECTION_RTL

onSaveInstanceState

Added in API level 1 
public Parcelable onSaveInstanceState ()

Hook allowing a view to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can not be reconstructed later. For example, you will never store your current position on screen because that will be computed again when a new instance of the view is placed in its view hierarchy.

Some examples of things you may store here: the current cursor position in a text view (but usually not the text itself since that is stored in a content provider or other persistent storage), the currently selected item in a list view.
If you override this method you must call through to the superclass implementation.

Returns
Parcelable Returns a Parcelable object containing the view's current dynamic state, or null if there is nothing interesting to save.

onScreenStateChanged

Added in API level 16 
public void onScreenStateChanged (int screenState)

This method is called whenever the state of the screen this view is attached to changes. A state change will usually occurs when the screen turns on or off (whether it happens automatically or the user does it manually.)

Parameters
screenState int: The new state of the screen. Can be either View.SCREEN_STATE_ON or View.SCREEN_STATE_OFF

onTextContextMenuItem

Added in API level 3 
public boolean onTextContextMenuItem (int id)

Called when a context menu option for the text view is selected. Currently this will be one of R.id.selectAll, R.id.cut, R.id.copy, R.id.paste, R.id.pasteAsPlainText (starting at API level\u202f23) or R.id.shareText.

Parameters
id int

Returns
boolean true if the context menu item action was performed.

onTouchEvent

Added in API level 1 
public boolean onTouchEvent (MotionEvent event)

Implement this method to handle touch screen motion events.

If this method is used to detect click actions, it is recommended that the actions be performed by implementing and calling performClick(). This will ensure consistent system behavior, including:

  • obeying click sound preferences
  • dispatching OnClickListener calls
  • handling ACTION_CLICK when accessibility features are enabled

Parameters
event MotionEvent: The motion event.
Returns
boolean True if the event was handled, false otherwise.

onTrackballEvent

Added in API level 1 
public boolean onTrackballEvent (MotionEvent event)

Implement this method to handle trackball motion events.

The relative movement of the trackball since the last event can be retrieve with MotionEvent.getX() and MotionEvent.getY(). These are normalized so that a movement of 1 corresponds to the user pressing one DPAD key (so they will often be fractional values, representing the more fine-grained movement information available from a trackball).

Parameters
event MotionEvent: The motion event.
Returns
boolean True if the event was handled, false otherwise.

onVisibilityAggregated

Added in API level 24 
public void onVisibilityAggregated (boolean isVisible)

Called when the user-visibility of this View is potentially affected by a change to this view itself, an ancestor view or the window this view is attached to.
If you override this method you must call through to the superclass implementation.

Parameters
isVisible boolean: true if this view and all of its ancestors are View.VISIBLE and this view's window is also visible

onWindowFocusChanged

Added in API level 1 
public void onWindowFocusChanged (boolean hasWindowFocus)

Called when the window containing this view gains or loses focus. Note that this is separate from view focus: to receive key events, both your view and its window must have focus. If a window is displayed on top of yours that takes input focus, then your own window will lose focus but the view focus will remain unchanged.

Parameters
hasWindowFocus boolean: True if the window containing this view now has focus, false otherwise.

performLongClick

Added in API level 1 
public boolean performLongClick ()

Calls this view's OnLongClickListener, if it is defined. Invokes the context menu if the OnLongClickListener did not consume the event.

Returns
boolean true if one of the above receivers consumed the event, false otherwise

removeTextChangedListener

Added in API level 1 
public void removeTextChangedListener (TextWatcher watcher)

Removes the specified TextWatcher from the list of those whose methods are called whenever this TextView's text changes.

Parameters
watcher TextWatcher

sendAccessibilityEventUnchecked

Added in API level 4 
public void sendAccessibilityEventUnchecked (AccessibilityEvent event)

This method behaves exactly as sendAccessibilityEvent(int) but takes as an argument an empty AccessibilityEvent and does not perform a check whether accessibility is enabled.

If an AccessibilityDelegate has been specified via calling setAccessibilityDelegate(android.view.View.AccessibilityDelegate) its AccessibilityDelegate#sendAccessibilityEventUnchecked(View, AccessibilityEvent) is responsible for handling this call.

Parameters
event AccessibilityEvent: The event to send.

setAllCaps

Added in API level 14 
public void setAllCaps (boolean allCaps)

Sets the properties of this field to transform input to ALL CAPS display. This may use a "small caps" formatting if available. This setting will be ignored if this field is editable or selectable. This call replaces the current transformation method. Disabling this will not necessarily restore the previous behavior from before this was enabled.

Related XML Attributes:

Parameters
allCaps boolean

setAutoLinkMask

Added in API level 1 
public final void setAutoLinkMask (int mask)

Sets the autolink mask of the text. See Linkify.ALL and peers for possible values.

Note: Linkify.MAP_ADDRESSES is deprecated and should be avoided; see its documentation.

Related XML Attributes:

Parameters
mask int

IllegalArgumentException if any of the configuration params are invalid.

setAutoSizeTextTypeUniformWithPresetSizes

Added in API level 26 
public void setAutoSizeTextTypeUniformWithPresetSizes (int[] presetSizes, 
                int unit)

Specify whether this widget should automatically scale the text to try to perfectly fit within the layout bounds. If at least one value from the presetSizes is valid then the type of auto-size is set to AUTO_SIZE_TEXT_TYPE_UNIFORM.

Related XML Attributes:

Parameters
presetSizes int: an int array of sizes in pixels This value cannot be null.
unit int: the desired dimension unit for the preset sizes above. See TypedValue for the possible dimension units

setBreakStrategy

Added in API level 23 
public void setBreakStrategy (int breakStrategy)

Sets the break strategy for breaking paragraphs into lines. The default value for TextView is Layout#BREAK_STRATEGY_HIGH_QUALITY, and the default value for EditText is Layout#BREAK_STRATEGY_SIMPLE, the latter to avoid the text "dancing" when being edited.

Enabling hyphenation with either using Layout#HYPHENATION_FREQUENCY_NORMAL or Layout#HYPHENATION_FREQUENCY_FULL while line breaking is set to one of Layout#BREAK_STRATEGY_BALANCED, Layout#BREAK_STRATEGY_HIGH_QUALITY improves the structure of text layout however has performance impact and requires more time to do the text layout.

Compared with setLineBreakStyle(int), line break style with different strictness is evaluated in the ICU to identify the potential breakpoints. In setBreakStrategy(int), line break strategy handles the post processing of ICU's line break result. It aims to evaluate ICU's breakpoints and break the lines based on the constraint.

setShiftDrawingOffsetForStartOverhang

Added in API level 35 
public void setShiftDrawingOffsetForStartOverhang (boolean shiftDrawingOffsetForStartOverhang)

Set true for shifting the drawing x offset for showing overhang at the start position. This flag is ignored if the getUseBoundsForWidth() is false. If this value is false, the TextView draws text from the zero even if there is a glyph stroke in a region where the x coordinate is negative. TextView clips the stroke in the region where the X coordinate is negative unless the parents has ViewGroup#getClipChildren() to true. This is useful for aligning multiple TextViews vertically. If this value is true, the TextView draws text with shifting the x coordinate of the drawing bounding box. This prevents the clipping even if the parents doesn't have ViewGroup#getClipChildren() to true. This value is false by default.

Parameters
shiftDrawingOffsetForStartOverhang boolean: true for shifting the drawing offset for showing the stroke that is in the region whre the x coorinate is negative.

Returns
MovementMethod

getLeftFadingEdgeStrength

Added in API level 1 
protected float getLeftFadingEdgeStrength ()

Returns the strength, or intensity, of the left faded edge. The strength is a value between 0.0 (no fade) and 1.0 (full fade). The default implementation returns 0.0 or 1.0 but no value in between. Subclasses should override this method to provide a smoother fade transition when scrolling occurs.

Returns
float the intensity of the left fade as a float between 0.0f and 1.0f

getLeftPaddingOffset

Added in API level 2 
protected int getLeftPaddingOffset ()

Amount by which to extend the left fading region. Called only when isPaddingOffsetRequired() returns true.

Returns
int The left padding offset in pixels.

getRightFadingEdgeStrength

Added in API level 1 
protected float getRightFadingEdgeStrength ()

Returns the strength, or intensity, of the right faded edge. The strength is a value between 0.0 (no fade) and 1.0 (full fade). The default implementation returns 0.0 or 1.0 but no value in between. Subclasses should override this method to provide a smoother fade transition when scrolling occurs.

Returns
float the intensity of the right fade as a float between 0.0f and 1.0f

getRightPaddingOffset

Added in API level 2 
protected int getRightPaddingOffset ()

Amount by which to extend the right fading region. Called only when isPaddingOffsetRequired() returns true.

Returns
int The right padding offset in pixels.

getTopPaddingOffset

Added in API level 2 
protected int getTopPaddingOffset ()

Amount by which to extend the top fading region. Called only when isPaddingOffsetRequired() returns true.

Returns
int The top padding offset in pixels.

isPaddingOffsetRequired

Added in API level 2 
protected boolean isPaddingOffsetRequired ()

If the View draws content inside its padding and enables fading edges, it needs to support padding offsets. Padding offsets are added to the fading edges to extend the length of the fade so that it covers pixels drawn inside the padding. Subclasses of this class should override this method if they need to draw content inside the padding.

Returns
boolean True if padding offset must be applied, false otherwise.

onAttachedToWindow

Added in API level 1 
protected void onAttachedToWindow ()

This is called when the view is attached to a window. At this point it has a Surface and will start drawing. Note that this function is guaranteed to be called before onDraw(android.graphics.Canvas), however it may be called any time before the first onDraw -- including before or after onMeasure(int, int).
If you override this method you must call through to the superclass implementation.

onConfigurationChanged

Added in API level 8 
protected void onConfigurationChanged (Configuration newConfig)

Called when the current configuration of the resources being used by the application have changed. You can use this to decide when to reload resources that can changed based on orientation and other configuration characteristics. You only need to use this if you are not relying on the normal Activity mechanism of recreating the activity instance upon a configuration change.

Parameters
newConfig Configuration: The new resource configuration.

onCreateContextMenu

Added in API level 1 
protected void onCreateContextMenu (ContextMenu menu)

Views should implement this if the view itself is going to add items to the context menu.

Parameters
menu ContextMenu: the context menu to populate

onCreateDrawableState

Added in API level 1 
protected int[] onCreateDrawableState (int extraSpace)

Generate the new Drawable state for this view. This is called by the view system when the cached Drawable state is determined to be invalid. To retrieve the current state, you should use getDrawableState().

Parameters
extraSpace int: if non-zero, this is the number of extra entries you would like in the returned array in which you can place your own states.
Returns
int[] Returns an array holding the current Drawable state of the view.

onDraw

Added in API level 1 
protected void onDraw (Canvas canvas)

Implement this to do your drawing.

Parameters
canvas Canvas: the canvas on which the background will be drawn This value cannot be null.

onFocusChanged

Added in API level 1 
protected void onFocusChanged (boolean focused, 
                int direction, 
                Rect previouslyFocusedRect)

Called by the view system when the focus state of this view changes. When the focus change event is caused by directional navigation, direction and previouslyFocusedRect provide insight into where the focus is coming from. When overriding, be sure to call up through to the super class so that the standard focus handling will occur.
If you override this method you must call through to the superclass implementation.

Parameters
focused boolean: True if the View has focus; false otherwise.
direction int: The direction focus has moved when requestFocus() is called to give this view focus. Values are View.FOCUS_UP, View.FOCUS_DOWN, View.FOCUS_LEFT, View.FOCUS_RIGHT, View.FOCUS_FORWARD, or View.FOCUS_BACKWARD. It may not always apply, in which case use the default. Value is View.FOCUS_BACKWARD, View.FOCUS_FORWARD, View.FOCUS_LEFT, View.FOCUS_UP, View.FOCUS_RIGHT, or View.FOCUS_DOWN
previouslyFocusedRect Rect: The rectangle, in this view's coordinate system, of the previously focused view. If applicable, this will be passed in as finer grained information about where the focus is coming from (in addition to direction). Will be null otherwise.

onLayout

Added in API level 1 
protected void onLayout (boolean changed, 
                int left, 
                int top, 
                int right, 
                int bottom)

Called from layout when this view should assign a size and position to each of its children. Derived classes with children should override this method and call layout on each of their children.

Parameters
changed boolean: This is a new size or position for this view
left int: Left position, relative to parent
top int: Top position, relative to parent
right int: Right position, relative to parent
bottom int: Bottom position, relative to parent

onMeasure

Added in API level 1 
protected void onMeasure (int widthMeasureSpec, 
                int heightMeasureSpec)

Measure the view and its content to determine the measured width and the measured height. This method is invoked by measure(int, int) and should be overridden by subclasses to provide accurate and efficient measurement of their contents.

CONTRACT: When overriding this method, you must call setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by measure(int, int). Calling the superclass' onMeasure(int, int) is a valid use.

The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override onMeasure(int, int) to provide better measurements of their content.

If this method is overridden, it is the subclass's responsibility to make sure the measured height and width are at least the view's minimum height and width (getSuggestedMinimumHeight() and getSuggestedMinimumWidth()).

Parameters
widthMeasureSpec int: horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
heightMeasureSpec int: vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

onScrollChanged

Added in API level 1 
protected void onScrollChanged (int horiz, 
                int vert, 
                int oldHoriz, 
                int oldVert)

This is called in response to an internal scroll in this view (i.e., the view scrolled its own contents). This is typically as a result of scrollBy(int, int) or scrollTo(int, int) having been called.

Parameters
horiz int: Current horizontal scroll origin.
vert int: Current vertical scroll origin.
oldHoriz int: Previous horizontal scroll origin.
oldVert int: Previous vertical scroll origin.

onSelectionChanged

Added in API level 3 
protected void onSelectionChanged (int selStart, 
                int selEnd)

This method is called when the selection has changed, in case any subclasses would like to know.

Note: Always call the super implementation, which informs the accessibility subsystem about the selection change.


If you override this method you must call through to the superclass implementation.

Parameters
selStart int: The new selection start location.
selEnd int: The new selection end location.

onTextChanged

Added in API level 1 
protected void onTextChanged (CharSequence text, 
                int start, 
                int lengthBefore, 
                int lengthAfter)

This method is called when the text is changed, in case any subclasses would like to know. Within text, the lengthAfter characters beginning at start have just replaced old text that had length lengthBefore. It is an error to attempt to make changes to text from this callback.

Parameters
text CharSequence: The text the TextView is displaying
start int: The offset of the start of the range of the text that was modified
lengthBefore int: The length of the former text that has been replaced
lengthAfter int: The length of the replacement modified text

onVisibilityChanged

Added in API level 8 
protected void onVisibilityChanged (View changedView, 
                int visibility)

Called when the visibility of the view or an ancestor of the view has changed.

Parameters
changedView View: The view whose visibility changed. May be this or an ancestor view. This value cannot be null.
visibility int: The new visibility, one of View.VISIBLE, View.INVISIBLE or View.GONE. Value is View.VISIBLE, View.INVISIBLE, or View.GONE

setFrame

Added in API level 1 
protected boolean setFrame (int l, 
                int t, 
                int r, 
                int b)

Parameters
l int

t int

r int

b int

Returns
boolean

verifyDrawable

Added in API level 1 
protected boolean verifyDrawable (Drawable who)

If your view subclass is displaying its own Drawable objects, it should override this function and return true for any Drawable it is displaying. This allows animations for those drawables to be scheduled.

Be sure to call through to the super class when overriding this function.
If you override this method you must call through to the superclass implementation.

Parameters
who Drawable: This value cannot be null.
Returns
boolean boolean If true then the Drawable is being displayed in the view; else false and it is not allowed to animate.
