I am not able to change the background color of the selected item in the navigation drawer as well as the text color of the selected item. I used the code here to create the navigation drawer: Support Navigation Drawer.
When I try to change it like Navigation Drawer item background colour for selected item
It does not work. By default it uses a light grey background and the color of the action menu bar of the normal app screen. Right now I don't think it's possible at all.
