Set Background Color of Navigation Drawer

Question

I wanted to set the background color of my Navigation drawer in java but it seems as setBackgroundColor and all similar methods have no effect. Only the XML line

Answer 1

I just solved my own problem.

I totally forgot that it's not the DrawerLayout I want to set the background to, but the ListView inside.

I admit I made it somewhat hard for you guys without adding code to my post -.-'

So instead of:

private DrawerLayout mDrawerLayout;
(...)
mDrawerLayout.setBackgroundResource(int);

I had to do this:

private ListView mDrawerList;
(...)
mDrawerList.setBackgroundResource(int);
