How to create a simple divider in the new NavigationView?

Question

Google introduced the NavigationView in the Design Support Library version 22.2.0 with which you can create a drawer very easily using a menu resource.

How can I create a simple divider line between two items? Grouping the items didn't work. Creating a sub items section does create a divider line, but it requires a title, which I don't want.

Any help would be appreciated.

All you need to do is define a group with an unique ID. I have checked the implementation, and if groups have different ids, it will create a divider.

Example menu, creating the separator:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity">

    <group android:id="@+id/grp1" android:checkableBehavior="single" >
        <item
            android:id="@+id/navigation_item_1"
            android:checked="true"
            android:icon="@drawable/ic_home"
            android:title="@string/navigation_item_1" />
    </group>

    <group android:id="@+id/grp2" android:checkableBehavior="single" >
        <item
            android:id="@+id/navigation_item_2"
            android:icon="@drawable/ic_home"
            android:title="@string/navigation_item_2" />
    </group>
</menu>
