Bottom menu with ActionBarSherlock

Question

Im trying implement the bottom menu with ActionBarSherlock. In Android 2.1, the menu are displayed, but in the Android 4, the menu is not displayed. What's wrong?

Below, the code:

public class Atividade extends Activity implements OnCreateOptionsMenuListener {

     ActionBarSherlock mSherlock = ActionBarSherlock.wrap(this);

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (android.os.Build.VERSION.SDK_INT < 11)
            // Remove title bar
            this.requestWindowFeature(Window.FEATURE_NO_TITLE);

        setTheme(R.style.Theme_Sherlock_Light_DarkActionBar);

        mSherlock.setUiOptions(ActivityInfo.UIOPTION_SPLIT_ACTION_BAR_WHEN_NARROW);        
        mSherlock.setContentView(R.layout.atividade);
        .
        .
        .               
    }

Below, the menu options:

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        menu.add("Agenda")
            .setIcon(R.drawable.ic_compose)
            // .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_WITH_TEXT);
            .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_WITH_TEXT);

        menu.add("Favoritos")
        .setIcon(R.drawable.favoritos)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_WITH_TEXT);

        menu.add("Mapa")
            .setIcon(R.drawable.maps)
            .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_WITH_TEXT);

        com.actionbarsherlock.view.SubMenu subMenu1 = menu.addSubMenu("Compartilhar");              
        subMenu1.add("Facebook");
        subMenu1.add("Twitter");
        subMenu1.add("E-Mail");
        subMenu1.add("SMS");

        MenuItem subMenu1Item = (MenuItem) subMenu1.getItem();
        subMenu1Item.setIcon(R.drawable.compartilhar);
        subMenu1Item.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_WITH_TEXT);

        return true;
    }

}

Make your Activity extend SherlockActivity. As Jake Wharton suggests, use the manifest to set the theme and uiOptions attributes on your activity.
