Bear in mind that when you're using a ListView, not all your item views are created and visible at the same time. You are creating or modifying the visible view on demand based on what is visible at the moment.
If you want decide if a radio button in a ListView should be active or inactive at any moment, you need to store that in some structure accessible to the adapter so that when you create or update the list item view, you can enable or disable the button appropriately. The radio button group as a whole isn't going to help you precisely because not all the buttons are visible and active at the same time so they can't all be toggled automatically. I know this sounds complicated but that's just how ListView is optimized to handle an arbitrarily large number of items. You might be better off just using a ScrollView if your list of items is not prohibitively long.
