android - Select only one table row and Deselect others -

i have table layout table rows being added dynamically database. need programmatically choose 1 table row , deselect previous choosen. similar listview onitemclick. reasons can't use listview.

you add click listener on table rows. see code below:

private int selectedindex = -1;  private tablelayout tablelayout;  private void inittablelayout() {     view.onclicklistener clicklistener = new view.onclicklistener() {         @override         public void onclick(view v) {             integer index = (integer) v.gettag();             if (index != null) {                 selectrow(index);             }         }     };      tablelayout = (tablelayout) findviewbyid(r.id.table_layout);     final tablerow tr = new tablerow(this);     tr.settag(0);     tr.setonclicklistener(clicklistener);      // add views on tr      tablelayout.addview(tr, 0, new tablelayout.layoutparams(             tablerow.layoutparams.match_parent,             tablerow.layoutparams.wrap_content));      final tablerow tr2 = new tablerow(this);     tr2.settag(1);     tr2.setonclicklistener(clicklistener);      // add views on tr2      tablelayout.addview(tr2, 1, new tablelayout.layoutparams(             tablerow.layoutparams.match_parent,             tablerow.layoutparams.wrap_content));      ....  }  private void selectrow(int index) {     if (index != selectedindex) {         if (selectedindex >= 0) {             deselectrow(selectedindex);         }         tablerow tr = (tablerow) tablelayout.getchildat(index);         tr.setbackgroundcolor(color.gray);  // selected item bg color         selectedindex = index;     } }  private void deselectrow(int index) {     if (index >= 0) {         tablerow tr = (tablerow) tablelayout.getchildat(index);         tr.setbackgroundcolor(color.transparent);     } }
