ConstantValueDescription
normal0x00000000 There are no special semantics associated with this editor.
actionUnspecified0x00000000 There is no specific action associated with this editor, let the editor come up with its own if it can. Corresponds to IME_NULL.
actionNone0x00000001 This editor has no action associated with it. Corresponds to IME_ACTION_NONE.
actionGo0x00000002 The 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 IME_ACTION_GO.
actionSearch0x00000003 The 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 IME_ACTION_SEARCH.
actionSend0x00000004 The action key performs a "send" operation, delivering the text to its target. This is typically used when composing a message. Corresponds to IME_ACTION_SEND.
actionNext0x00000005 The action key performs a "next" operation, taking the user to the next field that will accept text. Corresponds to IME_ACTION_NEXT.

flagNoExtractUi0x10000000 Used 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 IME_FLAG_NO_EXTRACT_UI.

flagNoAccessoryAction0x20000000 Used 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 IME_FLAG_NO_ACCESSORY_ACTION.

flagNoEnterAction0x40000000 Used 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 IME_FLAG_NO_ENTER_ACTION.

This corresponds to the global attribute resource symbol imeOptions.

Must be one of the following constant values.

ConstantValueDescription
normal0
sans1
serif2
monospace3

This corresponds to the global attribute resource symbol typeface.

Related Methods

android:width

Makes the TextView be exactly this many pixels wide. You could get the same effect by specifying this number in the layout parameters.

Must be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), mm (millimeters).

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

This corresponds to the global attribute resource symbol width.

Public Methods

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 afterTextChanged(Editable) 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.

public final void append (CharSequence text)

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

public void append (CharSequence text, int start, int end)

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

public void beginBatchEdit ()

public boolean bringPointIntoView (int offset)

Move the point, specified by the offset, into the view if it is needed. This has to be called after layout. Returns true if anything changed.

public void cancelLongPress ()

Cancels a pending long press. Your subclass can use this if you want the context menu to come up if the user presses and holds at the same place, but you don't want it to come up if they press and then move around enough to cause scrolling.

public void clearComposingText ()

Use BaseInputConnection.removeComposingSpans() to remove any IME composing state from this text view.

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().

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

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 The auto complete text the user has selected.

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.

Parameters
outAttrs Fill in with attribute information about the connection.

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(TextView.OnEditorActionListener), or perform a standard operation for EditorInfo.IME_ACTION_NEXT 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 The code of the action being performed.

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().

public void onFinishTemporaryDetach ()

Called after onStartTemporaryDetach() when the container is done changing the view.

Returns
  • If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

public boolean onKeyMultiple (int keyCode, int repeatCount, KeyEvent event)

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

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

public boolean onKeyShortcut (int keyCode, KeyEvent event)

Called when an unhandled key shortcut event occurs.

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

public boolean onKeyUp (int keyCode, KeyEvent event)

Default implementation of KeyEvent.Callback.onKeyMultiple(): perform clicking of the view when KEYCODE_DPAD_CENTER or KEYCODE_ENTER is released.

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

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

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

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.

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

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.

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

public void onStartTemporaryDetach ()

This is called when a container is going to temporarily detach a child that currently has focus, with ViewGroup.detachViewFromParent. It will either be followed by onFinishTemporaryDetach() or onDetachedFromWindow() when the container is done. Generally this is currently only done ListView for a view with focus.

public boolean onTextContextMenuItem (int id)

Called when a context menu option for the text view is selected. Currently this will be one of: selectAll, startSelectingText, stopSelectingText, cut, copy, paste, copyUrl, or switchInputMethod.

public boolean onTouchEvent (MotionEvent event)

Implement this method to handle touch screen motion events.

Parameters
event The motion event.
Returns
  • True if the event was handled, false otherwise.

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 The motion event.
Returns
  • True if the event was handled, false otherwise.

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 True if the window containing this view now has focus, false otherwise.

public boolean performLongClick ()

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

Returns
  • True there was an assigned OnLongClickListener that was called, false otherwise is returned.

Sets the text that this TextView is to display (see setText(CharSequence)) and also sets whether it is stored in a styleable/spannable buffer and whether it is editable.

Related XML Attributes

public final void setText (CharSequence text)

Sets the string value of the TextView. TextView does not accept HTML-like formatting, which you can do with text strings in XML resource files. To style your strings, attach android.text.style.* objects to a SpannableString, or see the Available Resource Types documentation for an example of setting formatted text in the XML resource file.

Related XML Attributes

public void setTextAppearance (Context context, int resid)

Sets the text color, size, style, hint color, and highlight color from the specified TextAppearance resource.

public void setTextColor (int color)

Sets the text color for all the states (normal, selected, focused) to be this color.

Related XML Attributes

public void setTextColor (ColorStateList colors)

Sets the text color.

Related XML Attributes

public final void setTextKeepState (CharSequence text)

Like setText(CharSequence), except that the cursor position (if any) is retained in the new text.

Parameters
text The new text to place in the text view.

public final void setTextKeepState (CharSequence text, TextView.BufferType type)

Like setText(CharSequence, android.widget.TextView.BufferType), except that the cursor position (if any) is retained in the new text.

public void setTextScaleX (float size)

Sets the extent by which text should be stretched horizontally.

Related XML Attributes

public void setTextSize (int unit, float size)

Set the default text size to a given unit and value. See TypedValue for the possible dimension units.

Related XML Attributes
Parameters
unit The desired dimension unit.
size The desired size in the given units.

public void setTextSize (float size)

Set the default text size to the given value, interpreted as "scaled pixel" units. This size is adjusted based on the current density and user font size preference.

Related XML Attributes
Parameters
size The scaled pixel size.

public final void setTransformationMethod (TransformationMethod method)

Sets the transformation that is applied to the text that this TextView is displaying.

Related XML Attributes

public void setTypeface (Typeface tf, int style)

Sets the typeface and style in which the text should be displayed, and turns on the fake bold and italic bits in the Paint if the Typeface that you provided does not have all the bits in the style that you specified.

Related XML Attributes

public void setTypeface (Typeface tf)

Sets the typeface and style in which the text should be displayed. Note that not all Typeface families actually have bold and italic variants, so you may need to use setTypeface(Typeface, int) to get the appearance that you actually want.

public void setWidth (int pixels)

Makes the TextView exactly this many pixels wide. You could do the same thing by specifying this number in the LayoutParams.

Protected Methods

protected int computeHorizontalScrollRange ()

Compute the horizontal range that the horizontal scrollbar represents.

The range is expressed in arbitrary units that must be the same as the units used by computeHorizontalScrollExtent() and computeHorizontalScrollOffset().

The default range is the drawing width of this view.

Returns
  • the total horizontal range represented by the horizontal scrollbar

protected int computeVerticalScrollExtent ()

Compute the vertical extent of the horizontal scrollbar's thumb within the vertical range. This value is used to compute the length of the thumb within the scrollbar's track.

The range is expressed in arbitrary units that must be the same as the units used by computeHorizontalScrollRange() and computeVerticalScrollOffset().

The default extent is the drawing height of this view.

Returns
  • the vertical extent of the scrollbar's thumb

protected int computeVerticalScrollRange ()

Compute the vertical range that the vertical scrollbar represents.

The range is expressed in arbitrary units that must be the same as the units used by computeVerticalScrollExtent() and computeVerticalScrollOffset().

Returns
  • the total vertical range represented by the vertical scrollbar

    The default range is the drawing height of this view.

protected void drawableStateChanged ()

This function is called whenever the state of the view changes in such a way that it impacts the state of drawables being shown.

Be sure to call through to the superclass when overriding this function.

protected int getBottomPaddingOffset ()

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

Returns
  • The bottom padding offset in pixels.

protected boolean getDefaultEditable ()

Subclasses override this to specify that they have a KeyListener by default even if not specifically called for in the XML options.

protected MovementMethod getDefaultMovementMethod ()

Subclasses override this to specify a default movement method.

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

protected int getLeftPaddingOffset ()

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

Returns
  • The left padding offset in pixels.

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

protected int getRightPaddingOffset ()

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

Returns
  • The right padding offset in pixels.

protected int getTopPaddingOffset ()

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

Returns
  • The top padding offset in pixels.

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
  • True if padding offset must be applied, false otherwise.

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(Canvas), however it may be called any time before the first onDraw -- including before or after onMeasure(int, int).

protected void onCreateContextMenu (ContextMenu menu)

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

Parameters
menu the context menu to populate

protected void onDetachedFromWindow ()

This is called when the view is detached from a window. At this point it no longer has a surface for drawing.

protected void onDraw (Canvas canvas)

Implement this to do your drawing.

Parameters
canvas the canvas on which the background will be drawn

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.

Parameters
focused True if the View has focus; false otherwise.
direction 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 or View.FOCUS_RIGHT. It may not always apply, in which case use the default.
previouslyFocusedRect 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.

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 overriden 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 horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
heightMeasureSpec vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

protected void onSelectionChanged (int selStart, int selEnd)

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

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

protected void onTextChanged (CharSequence text, int start, int before, int after)

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

Parameters
text The text the TextView is displaying.
start The offset of the start of the range of the text that was modified.
before The offset of the former end of the range of the text that was modified. If text was simply inserted, this will be the same as start. If text was replaced with new text or deleted, the length of the old text was before-start.
after The offset of the end of the range of the text that was modified. If text was simply deleted, this will be the same as start. If text was replaced with new text or inserted, the length of the new text is after-start.

protected boolean setFrame (int l, int t, int r, int b)

Assign a size and position to this view. This is called from layout.

Parameters
l Left position, relative to parent
t Top position, relative to parent
r Right position, relative to parent
b Bottom position, relative to parent
Returns
  • true if the new size and position are different than the previous ones

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.

Parameters
who The Drawable to verify. Return true if it is one you are displaying, else return the result of calling through to the super class.
Returns
  • boolean If true than the Drawable is being displayed in the view; else false and it is not allowed to animate.
