you need onclick listener this. read adapters first

 onitemclicklistener itemlistener = new onitemclicklistener() {           public void onitemclick(adapterview<?> parent, view v,           int position, long rowid) {             intent intent = new intent().setclass(this, yournewactivity.class);             startactivity(intent);               }     };
