title: Losing current selection of list item after updating the listview items using notifyDataSetChanged
body: <p>I need to refresh the ListView items every second, and it works fine using notifyDataSetChanged(). After the refresh, the already selected item in the list is losing its selection. ie, it loses its selected item background. How can I maintain the selected state of already selected item, after each refresh?</p>
