Android: Append new data to already drawn ListView?

Question

so in short: I have chat server online which uses sockets, so when user types something in chat - it sends a message to all currently connected clients. In web browser I am using append javascript to add messages to chat window.

In Android I plan to use ListView ( I don't see any alternative ), so as user enters the chat - app loads all previous messages into ListView and creates it.

Now question is: Is it possible to append/add data to ListViews bottom without redrawing whole ListView? I want message arrival to be invisible to user, I don't want whole window to refresh.

Is it possible? Using fragments by the way.

of course possible. You just add your New Arrived data into your Array or ArrayList that you passed in your Adapter and called

adapter.notifyDataSetChanged();

look at another post notifyDataSetChanged example
