View flag indicating whether this view must have haptic feed-back enabled for events including lengthy presses.
The view drawing cache was mainly made obsolete While using the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache levels are mainly pointless and can easily end in a net loss in performance on account of the expense of creating and updating the layer. Within the unusual scenarios where caching levels are useful, including for alpha animations, setLayerType(int, android.graphics.Paint) handles this with components rendering.
x spot in the pivot place all around which the view will rotate and scale. This xml attribute sets the pivotX home on the View. May be a dimension price, that is a floating point amount appended which has a device like "14.
Uncover and return all focusable views which might be descendants of this view, potentially like this view if it is focusable itself.
Every one of the views in the window are organized in a single tree. It is possible to increase views either from code or by specifying a tree of views in one or more XML format data files. There are lots of specialized subclasses of views that act as controls or are effective at displaying text, illustrations or photos, or other content.
View.OnClickListener Interface definition for your callback being invoked whenever a view is clicked. interface
This technique was deprecated in API amount 28. The view drawing cache was largely manufactured out of date With all the introduction of components-accelerated rendering in API eleven. With hardware-acceleration, intermediate cache layers are largely needless and can easily cause a Web loss in overall performance because of the expense of making and updating the layer. Inside the scarce situations exactly where caching levels are valuable, including for alpha animations, setLayerType(int, android.graphics.
This process was deprecated in API stage 28. The view drawing cache was mainly made obsolete with the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache layers are mostly unwanted and can certainly result in click here a net reduction in functionality as a consequence of the expense of generating and updating the layer. From the scarce cases exactly where caching layers are beneficial, including for alpha animations, setLayerType(int, android.graphics.
Software levels ought to be prevented once the afflicted view tree updates typically. Each update would require to re-render the software program layer, that may possibly be gradual (specifically when components acceleration is turned on since the layer will have to be uploaded right into a hardware texture soon after every update.)
Returns the at the moment configured Drawable for your track with the vertical scroll bar if it exists, null otherwise.
Specifies a topic override for just a view. Any time a concept override is about, the view will probably be inflated using a Context themed with the required source.}
