hey think code working fine, in code instead of using
public void onclick(view arg0) { // todo auto-generated method stub textview tv=(textview) findviewbyid(r.id.pname); tv.settext("deleted item!"); } use
public void onclick(view view) { // todo auto-generated method stub textview tv=(textview) view.findviewbyid(r.id.pname); tv.settext("deleted item!"); } in instance since have not specified view context first view matches id, in case first row.
