      //各种动画模式
    ObjectAnimator translationY = ObjectAnimator.ofFloat(img, "translationY", 0f, 500f);
    ObjectAnimator alpha = ObjectAnimator.ofFloat(img, "alpha", 0f, 1f);
    ObjectAnimator rotation = ObjectAnimator.ofFloat(img, "rotation", 0f, 360f);

       //属性动画 先后运动
    AnimatorSet animatorSet=new AnimatorSet();
    animatorSet.play(translationY).with(alpha).with(rotation).with(scaleY).with(scaleX);
    animatorSet.setDuration(3000);
    animatorSet.start();
    //跳转 这个简单模式 当然你也可以 new Listener 那样方式有很多
    animatorSet.addListener(new AnimatorListenerAdapter() {
