Android電視關閉的動畫效果

public class TVOffAnimation extends Animation {    private int halfWidth;    private int halfHeight;    @Override    public void initialize(int width, int height, int parentWidth,            int parentHeight) {        super.initialize(width, height, parentWidth, parentHeight);        setDuration(500);        setFillAfter(true);        halfWidth = width / 2;        halfHeight = height / 2;        setInterpolator(new AccelerateDecelerateInterpolator());            }    @Override    protected void applyTransformation(float interpolatedTime, Transformation t) {        final Matrix matrix = t.getMatrix();        if (interpolatedTime < 0.8) {            matrix.preScale(1+0.625f*interpolatedTime, 1-interpolatedTime/0.8f+0.01f,halfWidth,halfHeight);        }else{            matrix.preScale(7.5f*(1-interpolatedTime),0.01f,halfWidth,halfHeight);        }    }}
