              getMenuInflater().inflate(R.menu.main, menu);

              return true;

       }

       @Override

       public boolean onOptionsItemSelected(MenuItem item) {

              // Handle action bar item clicks here. The action bar will

              // as you specify a parent activity in AndroidManifest.xml.

              int id = item.getItemId();

              if (id == R.id.action_settings) {
