Since I'm getting a few questions about the list view itself and what
I'm doing with it, here is that code. This code worked perfectly with
a simple_list_view_item_1 (or whatever it is called) and a regular
ArrayAdapter. All I did was switch out the layout resource I specify
for the adapter and I use my own custom adapter.
I have tried removing the CheckBox also because I was wondering if
that was stealing focus somehow but that made no difference. I think
the problem must have something to do with nesting LinearLayouts
inside the top level item.
