Android的，如何设置动画侦听器视图组？ [英] Android, How to set animation listener for view group?
问题描述
我有一个充当菜单的图像视图。当用户点击视图组（含5其他图像显示）将滑动由左到右。当在菜单中用户再次点击查看组幻灯片从右到左。
I have an image view which acts as menu. When user click it a view group (including 5 other image view) will slide from left to right. When user click on menu again view group slides from right to left.
我可以模拟这种行为，但滑动从右到左我希望看不到视图组但鉴于集团将放在它的位置后。我试图用 LinearLayout.setVisibiliy（View.Invisible），但在那一刻，我看不出滑动从右到左的动画。
I can simulate this behavior but after sliding right to left I expect to not see view group however view group will put on its place. I tried to use LinearLayout.setVisibiliy(View.Invisible) but at that moment i couldn't see sliding right to left animation.
这是我的code，任何的建议是AP preciated。
This is my code, any suggestion would be appreciated.

推荐答案
最后，我找到了解决办法。在这种情况下，我们应该用 aViewGroup.setLayoutAnimationListener（新AnimationListener（）...）并覆盖它的方法。
Finally I found the solution. In this case we should use aViewGroup.setLayoutAnimationListener(new AnimationListener()...) and override its methods.
所以我说：
groupLayout.setLayoutAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {}
@Override
public void onAnimationRepeat(Animation animation) {}
@Override
public void onAnimationEnd(Animation animation) {
if(menuState)
groupLayout.setVisibility(View.INVISIBLE);
menuState = !menuState;
Log.i("Menu state", "" + menuState);
}
});
