I have encountered a situation where I need to implement onOptionsItemSelected listener for the subMenu of an item. The menu xml file looks as below:

```
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:showAsAction="always"
        android:title="@string/action_settings">

         <menu>

            <item android:id="@+id/create_new"
                  android:title="Create New" />
            <item android:id="@+id/open"
                  android:title="Open" />
        </menu>
    </item>

    <item android:id="@+id/new_game"
          android:title="New Game"
          android:showAsAction="always"/>

    <item android:id="@+id/help"
          android:title="Help" 
          android:showAsAction="always"/>

</menu>

```

As I'm able to implement option listener for items, where as I want to know how to implement action listener for the **action\_settings** that have sub-menu items. 
 Kindly help me regarding this I have gogled but I was unable to find exact solution.
