title: Android notifyDataSetChanged() example
body: <p>Can some one give me an example tutorial or guide me in using <code>notifyDataSetChanged()</code> in my adapter? I'm getting my data from database and filling my listview. Also in my listview I have a button to like that particular content upon which my database value will be updated and the button text will change to "Liked". But i'm not sure how to refresh my listview again with the data from database.</p>
