title: Android NavigationView remove elevation
body: <p>I cannot remove elevation (shadow) of <code>NavigationView</code> for Lollipop and higher versions.
  I added <code>mDrawerLayout.setScrimColor(Color.TRANSPARENT);</code> to my <code>DrawerLayout</code>, but it affects on pre-Lollipop versions. I also tried to add <code>app:elevation="0dp"</code> and <code>android:elevation="0dp"</code> to my <code>NavigationView</code> but unsuccessful.</p>
