Android动画侦听器

Question

OnTouch一个ImageView我开始淡出动画:

    myImageView.setOnTouchListener(new View.OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
    v.startAnimation(fadeInAnimation);

我知道需要一个动画监听器才能找到动画完成的时间,但是如何附加它以便我可以获得动画刚刚完成的视图...我想在动画后设置视图的可见性已经完成了.

谢谢

Answer 1

我想你需要这个.

fadeInAnimation.setAnimationListener(new Animation.AnimationListener() {
    @Override
    public void onAnimationStart(Animation animation) {

    }

    @Override
    public void onAnimationEnd(Animation animation) {

    }

    @Override
    public void onAnimationRepeat(Animation animation) {

    }
});

Answer 2

如果您只需要一个结束动作就足够了 .withEndAction(Runnable)

fadeInAnimation.withEndAction(new Runnable() {
    @Override
    public void run() {
        ... do stuff
    }
})

如果有人需要以下解决方案kotlin：

fadeInAnimation.setAnimationListener(object: Animation.AnimationListener {
        override fun onAnimationRepeat(animation: Animation?) {
            TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
        }

        override fun onAnimationEnd(animation: Animation?) {
            TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
        }

        override fun onAnimationStart(animation: Animation?) {
            TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
        }

    })
