Background image covering the navdrawer

Question

I have an Activity with a navdrawer on it. And I’d like to put a background image on this Activity. But when I put the image, the Nav disappears, the image is over it. Nav does not lose function, if you click on the image it opens normally but does not appear. How can I resolve this issue?
