ValueAnimator 使用注意事項

1、動畫時間：如果是xml定義的值，需要使用getResources().getInteger(int)獲取值

2、動畫重復次數：Integer.MAX_VALUE 改為Integer.MAX_VALUE>>2

 

mIconAnimator = new ValueAnimator();
mIconAnimator.setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
mIconAnimator.addUpdateListener(
 new ValueAnimator.AnimatorUpdateListener() {
 @Override
 public void onAnimationUpdate(ValueAnimator animation) {
 int rotation = (int) animation.getAnimatedValue();
 Log.e("OkHttp", "rotation=" + rotation);
 ivButtonIcon.setRotation(rotation);
 }
 }
);
mIconAnimator.setRepeatCount(1);
mIconAnimator.setInterpolator(new AccelerateDecelerateInterpolator());

mIconAnimator.cancel();
int from = (int) (ivButtonIcon.getRotation() % 360f);
int to = reset ? 0 : 90;
if (from == to) return;
mIconAnimator.setIntValues(from, to);
mIconAnimator.start();
