The view drawing cache was mainly produced out of date Along with the introduction of hardware-accelerated rendering in API 11. With components-acceleration, intermediate cache layers are mainly pointless and can certainly end in a Internet decline in overall performance on account of the expense of creating and updating the layer. Within the uncommon circumstances where by caching layers are valuable, such as for alpha animations, setLayerType(int, android.graphics.Paint) handles this with hardware rendering.
If a nested scrolling child view would normally fling however it is at the edge of its possess information, it can use this technique to delegate the fling to its nested scrolling parent instead. The mum or dad may perhaps optionally consume the fling or observe a baby fling.
This constant was deprecated in API amount thirty. Use WindowInsets#getInsetsIgnoringVisibility(int) rather to retrieve insets that do not modify when process bars improve visibility point out.
Returns the callback set by setHandwritingDelegatorCallback(Runnable) which ought to be called whenever a stylus MotionEvent happens within this view's bounds. The callback need to only be termed in the UI thread.
Dispatch a touch about no matter if this view is shown. As an illustration, every time a View moves out with the display screen, it would receives a display trace indicating the view will not be shown. Programs shouldn't rely
Routinely identify whether the view should only allow interactions from AccessibilityServices Along with the AccessibilityServiceInfo.
Dispatch a single move of the nested scroll in development in advance of this view consumes any percentage of it. Nested pre-scroll functions are to nested scroll gatherings what contact intercept is to touch.
Cause an invalidate of the required spot to happen with a subsequent cycle from the occasion loop. void postInvalidateDelayed(long delayMilliseconds)
The view drawing cache was largely built obsolete Using the introduction of components-accelerated rendering in API 11. With components-acceleration, intermediate cache layers are mainly unneeded and can easily end in a Internet decline in effectiveness as a result of the expense of generating and updating the layer. Within the exceptional instances where read more by caching layers are practical, for example for alpha animations, setLayerType(int, android.graphics.Paint) handles this with components rendering.
Dispatch to collect the ViewTranslationRequests for translation purpose by traversing the hierarchy in the event the application requests ui translation. Normally, this method should really only be overridden by subclasses that offer a view hierarchy (like ViewGroup). Other lessons really should override View#onCreateViewTranslationRequest for typical view or override View#onVirtualViewTranslationResponses for view consists of Digital young children. When requested to get started on the ui translation, the program will contact this technique to traverse the view hierarchy to collect ViewTranslationRequests and make a Translator to translate the requests.
Default for the foundation view. The first robust directional character establishes the paragraph path. If there isn't a strong directional character, the paragraph route is definitely the viewu2019s resolved format course.}
