Question

I have a requirement that I need to dispaly ListView and at bottom of my List I have to display two buttons (scroll up/down).

Whenever user press on these buttons my list should scroll accordingly.

for this I have used

 if(view == scrollupbtn)
    {
        if(listViewPosition >= 1)
            listView.smoothScrollToPosition(-- listViewPosition);

    }
    else if(view == scrolldownbtn)
    {
        listView.smoothScrollToPosition(++ listViewPosition);

    }

This code able to scroll my listview but I am not able to see list item selector when I press my buttons..

I want to display default list item selector when I press my buttons..

Please let me know what to do for this..
