android.view.ViewGroup.dispatchGetDisplayList（ViewGroup.java:3147）

知道为什么会出现这种崩溃？跟踪只有本机代码，因此很难跟踪它。当我在Fragment内运行动画时，三星Galaxy s3平台4.1.2会发生这种情况，当动画结束时，我会为notifyDataSetChanged调用FragmentStatePagerAdapter。这个问题不是100％可重复的。

感谢。

跟踪：

2 个答案:

答案 0 :(得分：9)

修复很简单，但不知道为什么有效。

在AnimationListener的{​​{1}}回调中，我有一个触发onAnimationEnd的回调。我将该回调添加到notifyDataSetChanged并使用Runnable

运行Runnable 
getView().post

答案 1 :(得分：0)

很好的答案，但就像所有Android系统一样，这些答案的过时很快。 我现在将使用runOnUiThread。我在一个动画师作为私有类的基类中运行。有关runOnUiThread的更多信息，请参见
Android basics: running code in the UI thread 

    @Override
    public void onAnimationEnd(Animator animation) {

        //
        MyBaseActivity.this.runOnUiThread(new Runnable() {
            public void run() {
                Log.d("UI thread", "I am the UI thread");                    
            }
        });

    }
