本文介绍了一个关于ListView在数据更新时未能正确接收通知的问题，并提供了解决方案。问题出现在尝试从后台线程修改适配器内容时，解决方案是在主线程中使用data.addAll()和notifyDataSetChanged()方法。

发现一个有时候会出现的错误：
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(2131165196, class android.widget.ListView) with Adapter(class com.jovision.multiscreen.views.DeviceScanSelectDialog$DeviceAdapter)
需要data.addAll，Adapter.notifyDataSetChanged() 在主线程执行，
data .addAll(data_update) ;
if (data_update_size< 20){
    mListView .setPullLoadEnable(false) ;
}else {
    mListView .setPullLoadEnable(true) ;
}
onLoad();
mAlertAdapter.notifyDataSetChanged();

这个错误通常是由于在后台线程修改了适配器的内容而导致的。Android要求所有对UI的更改必须在UI线程上执行，否则就会出现这个错误。你需要确保所有对适配器的内容修改都在UI线程上执行，可以使用runOnUiThread方法来...

意思大体是，你的adapter的内容变化了，但是你的ListView并不知情。请保证你adapter的数据在主线程中进行更改！ public class OrderAdapter extends BaseAdapter { private ArrayList> lists; private Context context; private Handler handler; priv
