觸發：

    VideoWrapper videoWrapper = new VideoWrapper();
    AnimatorSet set = new AnimatorSet();
    set.playTogether(
        ObjectAnimator.ofFloat(videoWrapper, "width", 0, 1100),
        ObjectAnimator.ofFloat(videoWrapper, "height", 0, 1100)
    );
    set.addListener(new AnimatorListenerAdapter() {
        @Override
        public
 
 void onAnimationEnd(Animator animation) {
            super.onAnimationEnd(animation);
        }
    });
    set.setDuration(500).start();

VideoWrapper類（mVideoViewSurfaceView為顯示視訊的View）：

class VideoWrapper {
    private ViewGroup.LayoutParams params;
    VideoWrapper() {
        params = mVideoViewSurfaceView.getLayoutParams();
    }

    public
 
 int getWidth() {
        return params.width;
    }

    public int getHeight() {
        return params.height;
    }

    public void setWidth(float w) {
        params.width = (int) w;
        mVideoViewSurfaceView.setLayoutParams(params);
    }

    public void setHeight(float h) {
        params
 
.height = (int) h;
        mVideoViewSurfaceView.setLayoutParams(params);
    }
}
