通过不断的修改一个 View 的属性形成动画效果。
属性动画有多种实现方式，简单的动画可以使用 ObjectAnimator，复杂一些的用 ValueAnimator 结合 AnimatorSet 、PropertyValuesHolder 使用。

public void startScaleProperty(ImageView imageView) {
    imageView.clearAnimation();
    ObjectAnimator animatorY = ObjectAnimator.ofFloat(imageView, "scaleY", 1f, 0.7f, 1f);
    ObjectAnimator animatorX = ObjectAnimator.ofFloat(imageView, "scaleX", 1f, 0.7f, 1f);

    AnimatorSet animSet = new AnimatorSet();
    animSet.play(animatorY).with(animatorX);
    animSet.setDuration(300);


    animSet.start();
}


public void startRotationProperty(ImageView imageView) {
    imageView.clearAnimation();
    ObjectAnimator animator = ObjectAnimator.ofFloat(imageView, "rotationX", 0f, 360f, 720f);
    animator.setDuration(5000);
    animator.start();
}

public void startTranslationProperty(ImageView imageView) {
    imageView.clearAnimation();
    ObjectAnimator animator = ObjectAnimator.ofFloat(imageView, "translationY", 0f, 200f);
    animator.setDuration(300);
    animator.start();
}

public void startBounceProperty(ImageView imageView) {
    imageView.clearAnimation();

    ObjectAnimator animator = ObjectAnimator.ofFloat(imageView, "X", 10f, 200f);
    animator.setDuration(300);
    animator.setInterpolator(new BounceInterpolator());
    animator.start();
}

public void startColorProperty(ImageView imageView) {
    ValueAnimator animator = ObjectAnimator.ofInt(imageView, "backgroundColor", 0x00ff0000, 0x6600ff00);//对背景色颜色进行改变，操作的属性为"backgroundColor",此处必须这样写，不能全小写,后面的颜色为在对应颜色间进行渐变
    animator.setDuration(3000);
    animator.setEvaluator(new ArgbEvaluator());//如果要颜色渐变必须要ArgbEvaluator，来实现颜色之间的平滑变化，否则会出现颜色不规则跳动
    animator.start();

}

public void startValueProperty(ImageView imageView) {
    imageView.clearAnimation();

    /*动画开始位置，也就是物品的位置动画结束的位置，也就是购物车的位置 */
    Point startPosition = new Point(100, 100);

    Point controllPoint = new Point(830, 330);
    ValueAnimator animator = ValueAnimator.ofObject(new BizierEvaluator2(controllPoint), startPosition, new Point(600, 1000));
    animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {
            Point point = (Point) animation.getAnimatedValue();
            imageView.setX(point.getX());
            imageView.setY(point.getY());
        }
    });
    animator.setDuration(300);
    animator.start();
}


public void startSvgAnimation(ImageView imageView) {
    imageView.clearAnimation();
    imageView.setImageDrawable(imageView.getResources().getDrawable(R.drawable.animal_svg_vector));

    AnimatedVectorDrawable animatedVectorDrawable = (AnimatedVectorDrawable) imageView.getDrawable();
    animatedVectorDrawable.start();
}
