Question

listView经常出现这样的问题，怎么解决？

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. [in ListView(2131427641, class android.widget.ListView) with Adapter(class android.widget.HeaderViewListAdapter)]

当你的listview中的数据发生改变时，必须通知adapter告诉它数据变了，方法是：
adapter.notifyDataSetChanged();

由于这个方法实际上是在更新UI，所以必须在UI线程也就是主线程里进行。
