属性动画

        1.使用propertyValuesHolder，属性动画多组属性同时改变

[java] view plaincopy

public void propertyValuesHolder(View view)
    {
        PropertyValuesHolder pvhX = PropertyValuesHolder.ofFloat("alpha", 1f,
                0f, 1f);
        PropertyValuesHolder pvhY = PropertyValuesHolder.ofFloat("scaleX", 1f,
                0, 1f);
        PropertyValuesHolder pvhZ = PropertyValuesHolder.ofFloat("scaleY", 1f,
                0, 1f);
        ObjectAnimator.ofPropertyValuesHolder(view, pvhX, pvhY,pvhZ).setDuration(1000).start();
    }
