Hello, I'm using an ArrayAdapter to add items to a custom ListView and showing the results in my Android app. The problem I'm having is that the ArrayAdapter seems to wait until all items are in it before it shows the view.

Hey all, I have an ArrayAdapter powering a ListView. I would like to change the data behind the ArrayAdapter and update the ListView's. Sounds like notifyDataSetChanged(); would be exactly what I am looking for, but it updates the entire ListView, and I would prefer to update on a row-by-row basis. Is there a way to do this with Arra...

I thought I would just try to override ArrayAdapter.getFilter(), but that requires I ...
