Ahh you probably need to re-bind your adapter, or call notifyDataSetChanged() on your adapter.

For instance, in your onResume() method call listView.setAdapter(new MySpecialAdapter()). That way no matter if your program is resumed from your other activity, or some other program, it will refresh the data.
