java.lang.IllegalStateException : The content of the adapter has changed but HederListView did not receive a notification 错误

Question

我正在使用 HeaderListView在我的项目中。它工作正常。但是在一个地方，当我尝试使用 notifydatesetchanges 时，它会抛出 IllegalStateException。只有当我尝试快速滚动 ListView 时才会发生这种情况。

这是堆栈跟踪

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. [in ListView(-1, class HeaderListView$InternalListView) with Adapter(class android.widget.HeaderViewListAdapter)]

我尝试了很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);
            } 
      }
}

获取更多列表项的代码。

 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();
        }
    }        
}

实际上问题出在 HeaderListView 库中，但现在错误已修复。你可以在这个link中看到这个问题已经解决了。
