To create an action bar you have to create a resource file of resource type "Menu".

In that file you can have as much options as you want and can define them to be shown on the bar or ou the "three got" menu. Here is an example:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
    android:id="@+id/logout"
    android:icon="@drawable/ic_logout"
    android:title="@string/sign_out"
    app:showAsAction="ifRoom"/>
<item
    android:id="@+id/settings"
    android:icon="@drawable/abc_vector_test"
    android:title="@string/settings" />
</menu>

Note the @+id in the android:id definition. Note as well that if you add app:showAsAction="ifRoom" the option will be shown on the bar instead of the dropdown menu.

Then, in your activity, add the onCreateOptionsMenu(Menu menu) method. Something like:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.game_menu, menu);

    return super.onCreateOptionsMenu(menu);
}

Then the function that you showed in your question will catch the menu click events.
