Remarks

This class performs the graphical effect used at the edges of scrollable widgets when the user scrolls beyond the content bounds in 2D space.

EdgeEffect is stateful. Custom widgets using EdgeEffect should create an instance for each edge that should show the effect, feed it input data using the methods #onAbsorb(int), #onPull(float), and #onRelease(), and draw the effect using #draw(Canvas) in the widget's overridden android.view.View#draw(Canvas) method. If #isFinished() returns false after drawing, the edge effect's animation is not yet complete and the widget should schedule another drawing pass to continue the animation.

When drawing, widgets should draw their main content and child views first, usually by invoking super.draw(canvas) from an overridden draw method. (This will invoke onDraw and dispatch drawing to child views as needed.) The edge effect may then be drawn on top of the view's content using the #draw(Canvas) method.
