Answer 1

You seem to be pulling the list data from a DB. Is there a reason why you are using an ArrayAdapter instead of a CursorAdapter?

Anyway, you should call notifyDataSetChanged() on your list adapter when the data has changed so it can refresh the view.

Answer 2

you can add code to update your listview (via notifyDataSetChanged or some such) by overriding the onResume() method in your activity which is called whenever the activity is brought back to the foreground. See http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle
