This class was deprecated in API level 26.
Use other means to handle this functionality. This widget is merely a simple wrapper around a long-press handler.

This widget provides a simple utility for turning a continued long-press event into a series of clicks at some set frequency. There is no actual 'zoom' functionality handled by this widget directly. Instead, clients of this API should set up an onClickListener to handle zoom functionality. That click listener is called on a frequency determined by setZoomSpeed(long) whenever the user long-presses on the ZoomButton.

`int`	`DRAWING_CACHE_QUALITY_AUTO` This constant was deprecated in API level 28. The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache layers are largely unnecessary and can easily result in a net loss in performance due to the cost of creating and updating the layer. In the rare cases where caching layers are useful, such as for alpha animations, `setLayerType(int, android.graphics.Paint)` handles this with hardware rendering. For software-rendered snapshots of a small part of the View hierarchy or individual Views it is recommended to create a `Canvas` from either a `Bitmap` or `Picture` and call `draw(android.graphics.Canvas)` on the View. However these software-rendered usages are discouraged and have compatibility issues with hardware-only rendering features such as `Config.HARDWARE` bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback reports or unit testing the `PixelCopy` API is recommended.
`int`	`DRAWING_CACHE_QUALITY_HIGH` This constant was deprecated in API level 28. The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11.

`void`	`buildDrawingCache(boolean autoScale)` This method was deprecated in API level 28. The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache layers are largely unnecessary and can easily result in a net loss in performance due to the cost of creating and updating the layer. In the rare cases where caching layers are useful, such as for alpha animations, `setLayerType(int, android.graphics.Paint)` handles this with hardware rendering. For software-rendered snapshots of a small part of the View hierarchy or individual Views it is recommended to create a `Canvas` from either a `Bitmap` or `Picture` and call `draw(android.graphics.Canvas)` on the View. However these software-rendered usages are discouraged and have compatibility issues with hardware-only rendering features such as `Config.HARDWARE` bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback reports or unit testing the `PixelCopy` API is recommended.

`Bitmap`	`getDrawingCache()` This method was deprecated in API level 28. The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache layers are largely unnecessary and can easily result in a net loss in performance due to the cost of creating and updating the layer. In the rare cases where caching layers are useful, such as for alpha animations, `setLayerType(int, android.graphics.Paint)` handles this with hardware rendering. For software-rendered snapshots of a small part of the View hierarchy or individual Views it is recommended to create a `Canvas` from either a `Bitmap` or `Picture` and call `draw(android.graphics.Canvas)` on the View. However these software-rendered usages are discouraged and have compatibility issues with hardware-only rendering features such as `Config.HARDWARE` bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback reports or unit testing the `PixelCopy` API is recommended.

`void`	`setWillNotCacheDrawing(boolean willNotCacheDrawing)` This method was deprecated in API level 28. The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache layers are largely unnecessary and can easily result in a net loss in performance due to the cost of creating and updating the layer. In the rare cases where caching layers are useful, such as for alpha animations, `setLayerType(int, android.graphics.Paint)` handles this with hardware rendering. For software-rendered snapshots of a small part of the View hierarchy or individual Views it is recommended to create a `Canvas` from either a `Bitmap` or `Picture` and call `draw(android.graphics.Canvas)` on the View. However these software-rendered usages are discouraged and have compatibility issues with hardware-only rendering features such as `Config.HARDWARE` bitmaps, real-time shadows, and outline clipping.

`boolean`	`willNotCacheDrawing()` This method was deprecated in API level 28. The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache layers are largely unnecessary and can easily result in a net loss in performance due to the cost of creating and updating the layer.

Public methods

dispatchUnhandledMove

Added in API level 1

public boolean dispatchUnhandledMove (View focused, 
                int direction)

This method is the last chance for the focused view and its ancestors to respond to an arrow key. This is called when the focused view did not consume the key internally, nor could the view system find a new view in the requested direction to give focus to.

Parameters
`focused`	`View`: The currently focused view.
`direction`	`int`: The direction focus wants to move. One of FOCUS_UP, FOCUS_DOWN, FOCUS_LEFT, and FOCUS_RIGHT. Value is `View.FOCUS_LEFT`, `View.FOCUS_UP`, `View.FOCUS_RIGHT`, or `View.FOCUS_DOWN`

Returns
`boolean`	True if the this view consumed this unhandled move.

getAccessibilityClassName

Added in API level 23
Deprecated in API level 26

public CharSequence getAccessibilityClassName ()

Return the class name of this object to be used for accessibility purposes. Subclasses should only override this if they are implementing something that should be seen as a completely new class of view when used by accessibility, unrelated to the class it is deriving from. This is used to fill in AccessibilityNodeInfo.setClassName.

Returns
`CharSequence`

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.

onLongClick

Added in API level 1

public boolean onLongClick (View v)

Called when a view has been clicked and held.

Parameters
`v`	`View`: The view that was clicked and held.

Returns
`boolean`	true if the callback consumed the long click, false otherwise.

onTouchEvent

Added in API level 1

public boolean onTouchEvent (MotionEvent event)

Implement this method to handle pointer events.

This method is called to handle motion events where pointers are down on the view. For example, this could include touchscreen touches, stylus touches, or click-and-drag events from a mouse. However, it is not called for motion events that do not involve pointers being down, such as hover events or mouse scroll wheel movements.

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.

setEnabled

Added in API level 1

public void setEnabled (boolean enabled)

Set the enabled state of this view. The interpretation of the enabled state varies by subclass.

Parameters
`enabled`	`boolean`: True if this view is enabled, false otherwise.

setZoomSpeed

Added in API level 1

public void setZoomSpeed (long speed)

Sets the delay between calls to the widget's onClickListener.

Parameters
`speed`	`long`: The delay between calls to the click listener, in milliseconds
