使用surfaceview和画布缩放动画

属性动画也是一个很好的缩放选项,而且非常简单!这是我的代码,用于将布局缩小到0,然后恢复正常。你可以通过简单的修改得到你想要的。

    private void anim() {
    AnimatorSet set = new AnimatorSet();

    ValueAnimator fadeOld = ValueAnimator.ofFloat(1,(float)0);
    fadeOld.setDuration(100);
    fadeOld.setInterpolator(new AccelerateInterpolator());
    fadeOld.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator valueAnimator) {
            Float newValue = (Float) valueAnimator.getAnimatedValue();
            cardContainer.setScaleX(newValue);
            cardContainer.setScaleY(newValue);
            cardContainer.setAlpha(newValue);


        }
    });

    ValueAnimator showNew = ValueAnimator.ofFloat(0, 1);
    showNew.setDuration(150);
    showNew.setInterpolator(new DecelerateInterpolator());
    showNew.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator valueAnimator) {
            Float newValue = (Float) valueAnimator.getAnimatedValue();
            cardContainer.setScaleX(newValue);
            cardContainer.setScaleY(newValue);
            cardContainer.setAlpha(newValue);
        }
    });


    set.play(fadeOld);
    set.play(showNew).after(fadeOld);
    set.start();

}
