Navigation Drawer Decoration?

Good Evening, i'm looking for a decoration that can simply give the hint that there's a navigation drawer on the left hand side of my screen, there's a question on here already (unanswered) that asks the same thing.

Example: Clash of Clan's chat drawer decoration on the left hand side

or

I'd like the decoration to remain on screen even when the drawer is closed, aligned with the left hand side of my screen

Here's my xml file:

<RelativeLayout xmlns:android="http://ift.tt/nIICcg"
xmlns:tools="http://ift.tt/LrGmb4" android:layout_width="match_parent"
android:layout_height="match_parent"
