如何在动作栏中制作弹出微调器？

Question

我想将弹出微调器作为ActionBar中的一项。

现在，我的微调框看起来像一个下拉菜单，但我想使其像对话框一样显示。

 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.


MenuInflater mi=getMenuInflater();
mi.inflate(R.menu.main, menu);
mSpinnerItem1 = menu.findItem( R.id.menu_spinner1);
View view1 = mSpinnerItem1.getActionView();
if (view1 instanceof Spinner)
{
    final Spinner spinner = (Spinner) view1;
    spinner.setAdapter(ad1);


    spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

}

   return true;
}
