Android :: Know When ListView Is Done Being Populated

I have a child Activity that contains a ListView. This Activity is populated asynchronously from a SQLite cursor. The list items contain a TextView, a RadioButton, and a normal Button. The XML is shown below:

CODE:...............

I have to do some logic to determine which RadioButton is selected by default, and I can't do it until the ListView is already loaded. The problem is that with all the events I have tried so far (onCreate, onPostCreate, onResume, onWindowFocusChanged), the ListView child count is zero. I've also tried using the getView method in the ArrayAdapter class, but that method is called mutliple times and the ListView child count is potentially different every time, leading to unexpected results. Apparently, these events are firing before the ListView has finished being completely populating with its child items.

Is there an event I can listen for, or some other way to determine when the ListView is finished populating and has all of its children accessible to be modified programmatically?
