我有一个奇怪的问题 - 不时应该淡出我的控制（的ImageButton）不会立即一命呜呼动画。我使用的是淡出动画来隐藏它，然后在myListener的在其末端（onAnimationEnd）我提出了新的资源作为按钮上的图像。

I have a strange issue - from time to time the animation that should fade out my control (ImageButton) does not kick in immediately. I am using the fadeout animation to hide it and then in myListener on its end (onAnimationEnd) I put new resource as the image on the button.

在某处我的应用程序code：

Somewhere in my app code:

Animation a = AnimationUtils.loadAnimation(this,R.anim.fadeout); 
a.setAnimationListener(new myListener(location));
buttons[location].setAnimation(a);
a.startNow(); // regardless if its start() or startnNow() 
              // it will work in most of the cases but not 100% reliable
              // I actually can see in debug Log when its late, happens after few more clicks

然后在myListener.onAnimationEnd（动画）：

Then in myListener.onAnimationEnd(Animation a):

buttons[location].setImageResource(R.drawable.standard_button);

似乎还有一个规则，即每4个或第五动画没有开始... ...

Seems there is a rule that the every 4th or 5th animation does not start ...

感谢您的帮助！

推荐答案

buttons[location].invalidate(); 

在

a.startNow();
