Ok. So are you also agreeing that I should NOT be calling Adapter.notifyDatasetChanged() to have the ListView automatically refresh itself? And I should be updating the data in the cells myself behind the scenes when individual data changes (but the overall dataset count remains the same as before)? If so, this is complete news to me. This completely defeats the purpose of having an Adaptor, and breaks the MVC paradigm. The only thing I should have to do in my code is tell the Adaptor that my dataset has changed, and the view should redraw accordingly. Adaptor should have a notifyDatasetChangedAtIndexes(int[] indexes) at the very least, rather than force the developer to update the cells manually. I guess I'm surprised Google is indicating the need for manual updates of data in the cells. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
