Handle that on a listener.Try this:

textView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
      @Override
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
              Toast.makeText(context, "Position clicked: " + position, Toast.LENGTH_SHORT).show();
      }
});
