I have added about 80 view (which has buttons) in the DragSortListView. Then I remove the view with the DragSortListView removeItem(int which) method. Before the DragSortListView has finished removing view (i.e , it been in the reordering view stage) I click the view in the drag sort list view and the error is shown which tell me that

"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(2130968590, class com.mobeta.android.dslv.DragSortListView) with Adapter(class com.mobeta.android.dslv.DragSortListView$AdapterWrapper)] "

Below is my complete logcat. Any solution is welcome

I seem that I been lucky for a long time . Basically I used a loader to automatically update data on drag sort list view and I forgot to call notifyDataSetChanged() since I thought that calling swapCursor() on both onLoadFinished() and onLoaderReset() is enough. The problem is solved for now so I think this is a main reason for the error.
