Update SimpleCursorAdapter while maintaining scroll position in ListView

Question

My problem: My ListView resets its scroll position to the top whenever I update its contents through its (customized) SimpleCursorAdapter. I would like the ListView to main

Answer 1

Did the same in post execute of Async Task used following code worked for me

 Cursor cursor = mDataHelper.getWritableDatabase().query(
                        DataContract.Incares.TABLE_NAME,  // Table to Query
                        null, // all columns
                        null, // Columns for the "where" clause
                        null, // Values for the "where" clause
                        null, // columns to group by
                        null, // columns to filter by row groups
                        DataContract.Incares.UUID +" DESC" // sort order
                );
CursorAdapter.swapCursor(cursor);
CursorAdapter.notifyDataSetChanged();

with CursorAdapter being a global variable

Answer 2

I've had a similar problem: My CursorAdapter reset the scroll position whenever the contents of the cursor changed.

I didn't realize that I actually did set a new list adapter each time the data changed. I thought the cursor himself would notify the adapter about changes to it's content but in my case it is the ContentProvider that triggers LoaderManager.LoaderCallbacks.onLoadFinished() in my ListFragment. In that callback I now use CursorAdapter.changeCursor() instead of creating a new adapter and everything works just fine.

I hope this helps solving your problem.
