Question

我有一个简单的多媒体应用程序，从上到下覆盖70％的屏幕我有一个ImageView小部件，另外30％的屏幕我有10个按钮，每个按钮在ImageView内触发一个动画小部件。

问题在于，如果我点击例如按钮1然后立即按下按钮2，则按钮1的动画将停止，按钮2的动画将开始。如何在播放当前动画时禁用10个按钮？如何在动画结束后启用按钮？

我尝试使用thread.sleep（animationlenght）和TimeUnit.MILLISECONDS.sleep（animationlenght）将程序置于睡眠状态，但它不会阻止程序运行其他onClick事件。

您应该在动画运行时禁用所有按钮，因此在活动中创建对按钮的引用，并在需要时禁用它们。

您可以使用此类方法检查动画何时结束，然后重新启用按钮：

 private void checkIfAnimationDone(AnimationDrawable anim){
    final AnimationDrawable a = anim;
    int timeBetweenChecks = 300;
    Handler h = new Handler();
    h.postDelayed(new Runnable(){
        public void run(){
            if (a.getCurrent() != a.getFrame(a.getNumberOfFrames() - 1)){
                checkIfAnimationDone(a);
            } else{
                //here re-enable your buttons
            }
        }
    }, timeBetweenChecks);
};
