Wrapping the adding/updating code in PostExecute in runOnUiThread has no effect

Calling listView.requestLayout instead of notifyDataSetChanged fixes the problem

listView.requestLayout this solve the problem but still y its not working for notifyDataSetChanged .

I am experiencing the same issue, and even forcing listView.requestLayout resolves the issue. I'm testing on a Nexus 7 tablet with Android 4.2. If I scroll up and down while my AsyncTask is grabbing the next chunk of data, the app crashes as soon as the data adapter is updated with the new elements. The adapter update is called from my AsyncTask.onPostExecute, and I am calling notifyDatasetChanged() right after the data is updated. I have removed the loading view so the app won't crash, and replaced it with a loading view drawn on top of the listview instead. It would be good to get a resolution for this though. The footer view loading indicator is nicer than my solution.

I think this issues stems from the fact that getAdapter is returning the AmazingAdapter instead of the wrapped HeaderListViewAdapter causing a difference in count at times. I simply removed the getAdapter method from AmazingListView and haven't got the exception since.
