Android change the title color in XML

Question

I have this part of the code in drawer.xml.

<item android:id="@+id/navigation_item1"
            android:checkable="true"
            android:title="Map"
            android:textColor="#FFFFFF"
            android:icon="@mipmap/ic_launcher"/>

I want to change the color of "Map" to white. I tried android::textColor, it doesn't work. Can I get some help?

Thanks!
