我在项目中使用HeaderListView。它工作正常。但是在某个地方，当我尝试使用notifydatesetchanges时，它将引发IllegalStateException。仅当我尝试快速滚动列表视图时，才会发生这种情况。
这是堆栈跟踪
05-12 12:03:42.641: E/AndroidRuntime(22291): 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.

我尝试了许多解决方案，并进行了大量搜索，但没有找到任何可靠的解决方案。
这是我的代码。
HeaderListView listView;
MyAdapter myAdapter;
ArrayList<String> eventList = new ArrayList<String>();
第一次获取列表的代码。
private class GetList extends AsyncTask<String, Void, String> {
ArrayList<String> loadMoreList;
@Override
public String doInBackground(String... params) {
loadMoreList = WebFunctions.getEventList(params[0] ,params[1], params[2], params[3]);
return null;
}
@Override
public void onPreExecute() {
}
@Override
public void onPostExecute(String string) {
if(loadMoreList != null){
if(loadMoreList.size() > 0){
eventList.clear();
eventList.addAll(loadMoreList);
myAdapter = new MyAdapter(thisContext, eventList);
}
}
}
代码以获取更多列表项。
private class LoadMoreList extends AsyncTask<String, Void, String> {
ArrayList<String> loadMoreList;
@Override
public String doInBackground(String... params) {
loadMoreList = WebFunctions.getEventList(params[0] ,params[1], params[2], params[3]);
return null;
}
@Override
public void onPreExecute() {
}
@Override
public void onPostExecute(String string) {
if(loadMoreList != null){
if(loadMoreList.size() > 0){
eventList.addAll(loadMoreList);
myAdapter.notifyDataSetChanged();
}
}
}
最佳答案
实际的问题出在HeaderListView库中，但是现在该错误已得到解决。
您可以在此link中看到问题已解决。
关于java - java.lang.IllegalStateException:适配器的内容已更改，但HederListView没有收到通知，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/23602702/
