然后我们创建标签向上缩放的方法,代码如下: public void animationUp() { ObjectAnimator scaleX = ObjectAnimator.ofFloat(...tvHint, "scaleX", 0.6f); ObjectAnimator scaleY = ObjectAnimator.ofFloat(tvHint, "scaleY", 0.6f);...animatorSet.setDuration(100); animatorSet.setInterpolator(new DecelerateInterpolator()); animatorSet.play(scaleX...至于复原的动画,就更简单了: public void animationDown() { etContent.setVisibility(View.GONE); ObjectAnimator scaleX...= ObjectAnimator.ofFloat(tvHint, "scaleX", 1); ObjectAnimator scaleY = ObjectAnimator.ofFloat(tvHint
