protected virtual bool AwakenScrollBars (int startDelay);
[<Android.Runtime.Register("awakenScrollBars", "(I)Z", "GetAwakenScrollBars_IHandler")>]
abstract member AwakenScrollBars : int -> bool
override this.AwakenScrollBars : int -> bool

Parameters

startDelay
Int32

the delay, in milliseconds, after which the animation should start; when the delay is 0, the animation starts immediately

Returns

Boolean

true if the animation is played, false otherwise

Attributes
RegisterAttribute

Remarks

Trigger the scrollbars to draw. When invoked this method starts an animation to fade the scrollbars out after a fixed delay. If a subclass provides animated scrolling, the start delay should equal the duration of the scrolling animation.

The animation starts only if at least one of the scrollbars is enabled, as specified by #isHorizontalScrollBarEnabled() and #isVerticalScrollBarEnabled(). When the animation is started, this method returns true, and false otherwise. If the animation is started, this method calls #invalidate(); in that case the caller should not call #invalidate().

This method should be invoked every time a subclass directly updates the scroll parameters.

Trigger the scrollbars to draw. When invoked this method starts an animation to fade the scrollbars out after a default delay. If a subclass provides animated scrolling, the start delay should equal the duration of the scrolling animation.

The animation starts only if at least one of the scrollbars is enabled, as specified by #isHorizontalScrollBarEnabled() and #isVerticalScrollBarEnabled(). When the animation is started, this method returns true, and false otherwise. If the animation is started, this method calls #invalidate(); in that case the caller should not call #invalidate().

This method should be invoked every time a subclass directly updates the scroll parameters.

This method is automatically invoked by #scrollBy(int, int) and #scrollTo(int, int).
