FrameLayout is made to block out a region within the display to Display screen one item. GLSurfaceView
Returns this view's desire for reveal conduct when it gains aim. When this method returns genuine for a child view requesting aim, ancestor views responding to a focus alter in ViewParent#requestChildFocus(View, View) should really create a best effort and hard work to make the newly centered child totally obvious on the person.
Sets the id of a view just before which this a single is frequented in accessibility traversal. A display screen-reader ought to check out the information of the view ahead of the content from the 1 it precedes. Could be an integer price, like "100".
Trace indicating this view can be autofilled that has a credit card protection code. Can be used with both setAutofillHints(java.
Take note: The Android framework is responsible for measuring, laying out and drawing views. You shouldn't connect with procedures that perform these steps on views by yourself Unless of course you are literally employing a ViewGroup.
This regular was deprecated in API stage 28. The view drawing cache was mostly manufactured obsolete Using the introduction of hardware-accelerated rendering in API eleven. With components-acceleration, intermediate cache layers are largely avoidable and can certainly lead to a net decline in general performance resulting from the price of making and updating the layer. In the scarce scenarios the place caching layers are handy, for example for alpha animations, setLayerType(int, android.graphics.
View.OnScrollChangeListener Interface definition for the callback to be invoked once the scroll X or Y positions of the view transform. interface
Bring about an invalidate of the required region to happen over a subsequent cycle from the event loop. void postInvalidateDelayed(lengthy delayMilliseconds)
Application levels ought to be averted in the event the affected view tree updates typically. Every update will require to re-render the application layer, that may possibly be sluggish (specially when components acceleration is turned on since the layer will have to be uploaded right into a components texture after each and every update.)
To help touch filtering, call setFilterTouchesWhenObscured(boolean) or established the android:filterTouchesWhenObscured layout attribute to genuine. When enabled, the framework will discard touches which can be been given Each time the view's window is obscured check here by A different noticeable window for the touched place.
By default, Views are established using the topic with the Context item equipped to their constructor; nevertheless, another topic could be specified by using the android:topic attribute in format XML or by passing a ContextThemeWrapper on the constructor from code. If the android:theme attribute is used in XML, the desired concept is used in addition to the inflation context's topic (see LayoutInflater) and useful for the view alone as well as any child features.}
