The best way to do this(in my point of view) is to create a ListView with an custom Adapter (extend BaseAdapter, see documentation) and when you get another assynchronous message update the data on the list and call notifyDataSetChanged() from the adapter to redraw the list.

You are not doing the way it is supposed to be in Android.

Hope it helped!
