Question

我有一个ListView，我提供了一些选项，具体取决于从数据库获取的数据。单击该ListView的项目时，它应该打开一个活动。列表视图通常包含两个项目。当我点击其中一个项目时，一切正常。但是，如果我退出活动，然后点击其他项目，我会得到以下异常：

08-10 13:00:35.724  22877-22877/? E/MessageQueue-JNI﹕ java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes.

指向这一行：

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    onSwipeTouchListener.getGestureDetector().onTouchEvent(ev);
    return super.dispatchTouchEvent(ev);//Get the exception here.
}

ListView以这种方式填充：

adapter=new ListaTributosAdapter(c, SwipeActivity.beanElementosTributarios);
    listView.setAdapter(adapter);

其中SwipeActivity.beanElementosTributarios是一个静态数组列表，其中存储了我想在列表视图中显示的内容。此时，只有一个地方可以修改数组：

if(SwipeActivity.beanElementosTributarios==null){
                SwipeActivity.beanElementosTributarios=new ArrayList<>();
            }
            SwipeActivity.beanElementosTributarios.add(bean);

您可以在应用的另一个点更改arrayList，但尚未达到该应用的那一点。当我调试时，我看到arrayList有两个项目，应该这样。

我对这个例外感到疯狂。

任何人都可以帮助我吗？（如果您需要查看代码的其他部分，请询问）

谢谢...

编辑：如果我点击列表中的第一项，则显示确定。当我点击SECOND元素时，异常会引发异常。但是，如果我首先单击列表视图的SECOND元素，它会正常显示，但如果我在此之后单击FIRST元素，则会引发异常。

编辑2：这不是该问题的重复。 UI线程没有其他线程，此时适配器的arrayList不会更改。

找到了这个：https://code.google.com/p/android/issues/detail?id=71936。也许是一个错误？

Answer 1

更改列表中的数据后，必须在适配器上调用notifyDataSetChanged（）。错误地说适配器中的数据已更新，但视图显示旧数据。

涉及适配器的奇怪的IllegalStateException
