本文介绍了一种使用PropertyValuesHolder和ObjectAnimator实现视图动画的方法。通过设置scaleX和translationY属性的变化来完成动画效果，同时提供了设置动画监听器的方式。

public static void animateProperty(final View view, Animator.AnimatorListener animationListener) {
        /*ObjectAnimator a1 = ObjectAnimator.ofFloat(view, "scaleX", 1.1f, 1f);
        ObjectAnimator a2 = ObjectAnimator.ofFloat(view, "translationY", 575f, 0f);
        AnimatorSet set = new AnimatorSet();
        set.setDuration(150);
        set.playTogether(a1, a2);
        //set.setStartDelay(100);
        //set.playSequentially(a1,a2,a3);
        //set.play(a1).with(a2);
        //set.play(a3).after(a2);
        set.start();*/

        PropertyValuesHolder pvhX = PropertyValuesHolder.ofFloat("scaleX", 1.1f, 1f);
        PropertyValuesHolder pvhY = PropertyValuesHolder.ofFloat("translationY", 575f, 0f);

        ObjectAnimator animator = ObjectAnimator.ofPropertyValuesHolder(view, pvhX, pvhY).setDuration(150);
        animator.addListener(animationListener);
        animator.start();
    }
