  <pre><code>_spinner = (Spinner) view.findViewById(R.id.group_spinner);
  _groupAdaptor = new ArrayAdapter(getActivity(), 
                  android.R.layout.simple_spinner_dropdown_item, _itemGroupList);
  _spinner.setAdapter(_groupAdaptor);
  _spinner.setOnItemSelectedListener(this);
  </code></pre>

  <pre><code>_spinner.performClick();
  </code></pre>
