The view drawing cache was mainly made obsolete Along with the introduction of components-accelerated rendering in API 11. With hardware-acceleration, intermediate cache levels are largely needless and can easily bring about a Web loss in efficiency as a consequence of the price of producing and updating the layer. During the uncommon situations wherever caching levels are helpful, including for alpha animations, setLayerType(int, android.graphics.Paint) handles this with components rendering.
Retrieve the list of locations inside this view's submit-layout coordinate Area in which the program shouldn't intercept touch or other pointing gadget gestures. Don't modify the returned checklist.
A components layer will also be accustomed to enhance the rendering top quality when rotation transformations are utilized over a view. It will also be employed to stop possible clipping problems when implementing 3D transforms on a view.
Gets the coordinates of this view from the coordinate Area on the window which contains the view, irrespective of procedure decorations. In multi-window mode, the origin in the coordinate Area is the highest remaining corner from the window which contains the view. In full screen manner, the origin is the top still left corner from the system screen.
Indicates that the view includes a software package layer. A program layer is backed by a bitmap and causes the view to become rendered making use of Android's application rendering pipeline, regardless of whether components acceleration is enabled.
Rect: If the method returns genuine, is made up of the coordinates in the seen percentage of this view within the coordinate Place on the view's root view. If the method returns Fake, the contents of r are undefined.
Defines whether or not the vertical scrollbar observe really should generally be drawn. android:scrollbarDefaultDelayBeforeFade
Manually render this view (and all of its children) to the specified Canvas. The view needs to have now performed an entire format just before this perform is known as.
Layout container for any view hierarchy which can be scrolled because of the person, allowing for it to be bigger compared to Bodily Screen. ImageButton
This technique was deprecated in API amount 28. The view drawing cache was mainly built out of date with the introduction get more info of components-accelerated rendering in API eleven. With components-acceleration, intermediate cache levels are mostly unneeded and can certainly cause a Internet reduction in efficiency as a result of the price of making and updating the layer. Within the uncommon cases where caching levels are handy, for instance for alpha animations, setLayerType(int, android.graphics.
The view drawing cache was mainly created out of date Using the introduction of components-accelerated rendering in API 11. With hardware-acceleration, intermediate cache levels are largely unwanted and can easily end in a Internet loss in effectiveness as a consequence of the expense of creating and updating the layer. Inside the exceptional instances where by caching layers are helpful, which include for alpha animations, setLayerType(int, android.graphics.Paint) handles this with components rendering.}
