Cursor cursor; MyCursorAdapter adapter; onCreate(){ refresh(); adapter = new MyCursorAdapter( this, cursor ); setListAdapter( adapter ); } onResume(){ refresh() } refresh(){ // read prefs, build new where clause cursor = managedQuery( ...new where clause etc ...) } I guess I can understand why this is happening ...data isn't actually changing, just the contents of the cursor. > The only workaround I've found so far is to > > re-create the adapter onResume ...which obviously isn't the best approach > as > > I lose scroll position etc > > > If I change sort or filter conditions, as a user I would expect to be > > taken to the top of the list, since the previous scroll position is > > meaningless. > > For a sort, absolutely ..but if I'm re-setting the adapter then when the user drills down (versus jumping to preferences) then hits back, the scroll position is also reset. Perhaps a compromise would be to fire a broadcast from prefs that resets the adapter on the list. Then drill down and back won't be affected. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
