`int`	`CLIP_TO_PADDING_MASK` We clip to padding when FLAG_CLIP_TO_PADDING and FLAG_PADDING_NOT_NULL are set at the same time.
`int`	`FOCUS_AFTER_DESCENDANTS` This view will get focus only if none of its descendants want it.
`int`	`FOCUS_BEFORE_DESCENDANTS` This view will get focus before any of its descendants.
`int`	`FOCUS_BLOCK_DESCENDANTS` This view will block any of its descendants from getting focus, even if they are focusable.
`int`	`LAYOUT_MODE_CLIP_BOUNDS` This constant is a `layoutMode`.
`int`	`LAYOUT_MODE_OPTICAL_BOUNDS` This constant is a `layoutMode`.
`int`	`PERSISTENT_ALL_CACHES` 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,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(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`	`setVisibility(int visibility)` Set the visibility state of this view.
`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,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(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`	`setWillNotDraw(boolean willNotDraw)` If this view doesn't do any drawing on its own, set this flag to allow further optimizations.

`ActionMode`	`startActionMode(ActionMode.Callback callback)` Start an action mode with the default type `ActionMode.TYPE_PRIMARY`.
`void`	`startAnimation(Animation animation)` Start the specified animation now.
`final boolean`	`startDrag(ClipData data, View.DragShadowBuilder shadowBuilder, Object myLocalState, int flags)` This method was deprecated in API level 24. Use `startDragAndDrop()` for newer platform versions.

`final void`	`updateDragShadow(View.DragShadowBuilder shadowBuilder)` Updates the drag shadow for the ongoing drag and drop operation.
`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.
`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.
