title: Refresh ListView items on every second
body: <p>Say I have data coming from server or local database. I am displaying them in listview. I have four-five textview in each listview item.Now I want to refresh listview item every second (requirement is something like this only).</p>
  
  <p>How should I achieve this. notifyDataSetChanged() is I am aware about. </p>
