EdgeEffectCompat

• java.lang.Object

Fields Summary
private Object	mEdgeEffect
private static final EdgeEffectImpl	IMPL

Constructors Summary
public EdgeEffectCompat(android.content.Context context) Construct a new EdgeEffect themed using the given context. Note: On platform versions that do not support EdgeEffect, all operations on the newly constructed object will be mocked/no-ops. param context Context to use for theming the effect mEdgeEffect = IMPL.newEdgeEffect(context);

Methods Summary
public boolean	draw(android.graphics.Canvas canvas) Draw into the provided canvas. Assumes that the canvas has been rotated accordingly and the size has been set. The effect will be drawn the full width of X=0 to X=width, beginning from Y=0 and extending to some factor < 1.f of height. param canvas Canvas to draw into return true if drawing should continue beyond this frame to continue the animation return IMPL.draw(mEdgeEffect, canvas);
public void	finish() Immediately finish the current animation. After this call {@link #isFinished()} will return true. IMPL.finish(mEdgeEffect);
public boolean	isFinished() Reports if this EdgeEffectCompat's animation is finished. If this method returns false after a call to {@link #draw(Canvas)} the host widget should schedule another drawing pass to continue the animation. return true if animation is finished, false if drawing should continue on the next frame. return IMPL.isFinished(mEdgeEffect);
public boolean	onAbsorb(int velocity) Call when the effect absorbs an impact at the given velocity. Used when a fling reaches the scroll boundary. When using a {@link android.widget.Scroller} or {@link android.widget.OverScroller}, the method getCurrVelocity will provide a reasonable approximation to use here. param velocity Velocity at impact in pixels per second. return true if the host view should invalidate, false if it should not. return IMPL.onAbsorb(mEdgeEffect, velocity);
public boolean	onPull(float deltaDistance) A view should call this when content is pulled away from an edge by the user. This will update the state of the current visual effect and its associated animation. The host view should always {@link android.view.View#invalidate()} if this method returns true and draw the results accordingly. param deltaDistance Change in distance since the last call. Values may be 0 (no change) to 1.f (full length of the view) or negative values to express change back toward the edge reached to initiate the effect. return true if the host view should call invalidate, false if it should not. return IMPL.onPull(mEdgeEffect, deltaDistance);
public boolean	onRelease() Call when the object is released after being pulled. This will begin the "decay" phase of the effect. After calling this method the host view should {@link android.view.View#invalidate()} if this method returns true and thereby draw the results accordingly. return true if the host view should invalidate, false if it should not. return IMPL.onRelease(mEdgeEffect);
public void	setSize(int width, int height) Set the size of this edge effect in pixels. param width Effect width in pixels param height Effect height in pixels IMPL.setSize(mEdgeEffect, width, height);
