Trouble With adding Costume View to action bar (Adding toggle view to action bar)

I would like to add a toggle switch to my action bar. I have seen several guide on this site on how to do so however non seem to make the view appear(No toggle switch appears in the action bar. It is ass if I did not add it). What am I doing wrong.

menu xml

<menu xmlns:android="http://ift.tt/nIICcg"
xmlns:app="http://ift.tt/GEGVYd"
xmlns:tools="http://ift.tt/LrGmb4" tools:context=".MainActivity">

<item
    android:id="@+id/switchId"
    android:title=""
    app:showAsAction="always"
    android:actionLayout="@layout/unit_toggle"
     />
<item
    android:id="@+id/action_settings"
    android:orderInCategory="100"
    android:title="@string/action_settings"
    app:showAsAction="never"/>

SwitchLayout

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://ift.tt/nIICcg"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<android.support.v7.widget.SwitchCompat
    android:id="@+id/switchAB"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true" />
</RelativeLayout>

Sorry if this is a dumb question, but I have been searching for nearly 2 hours and yet to figure out what I am doing wrong. Thanks in advanced for any help it is greatly appreciated.
