圆形展开缩放动画

关键代码:

final Animator circularReveal = ViewAnimationUtils.createCircularReveal(subsamplingScaleImageView, SystemUtils.getWindowWidth() / 2, ivScreenShot.getHeight() / 2, 0, SystemUtils.getWindowHeight() / 2);
                circularReveal.setInterpolator(new DecelerateInterpolator());
                circularReveal.setDuration(400);
                circularReveal.start();
