            <group android:id="@+id/group_1">

                    android:id="@+id/action_most_shared"
                    android:title="Most shared"

            </group>
            <group android:id="@+id/group_4">
                <item
                    android:id="@+id/action_most_read"
                    android:title="Most read"
                   />
            </group>

        </menu>

    </item>

    <item
        android:id="@+id/action_notification"
        android:actionLayout="@layout/lyt_notification_count"
        android:icon="@drawable/notification_navigation"
        android:orderInCategory="101"
        android:title="Notification"
        app:showAsAction="always" />

    <item
        android:id="@+id/action_search"
        android:icon="@drawable/search_navigation"
        android:orderInCategory="100"
        android:title="Search"
        app:actionViewClass="android.widget.SearchView"
        app:showAsAction="always" />
</menu>

So this is what I'm doing now. I need to draw a item divider between each item(Orderincatogory = 102). I don't know how to do that please help if anyone know the answer. These are in toolbar and I'm testing in kitkat and lollypop device.
