I created the Activity with the Wizard. I deleted what I am not interested in, for example, the floating action button.
Created my custom items in the activity_main_drawer.xml
The wizard created the onNavigationItemSelected function (see code below) and I added my code so it quits the activity and goes back to the Login Screen.
So I don't know why, I see nothing interesting in the logcat so this is a logical problem. I am a newbie and Navigation View scares me a lot... Let me know if I missed anything you need.

Edit:
So it may be confusing if I set the visibility to gone and I get use the layout I want right in this layout file because I get the screen without the toolbar, this is what I want. AND I want to keep that as well for the admin part, to check later in if the user is me, and if so, I get a new item in the drawer called Admin Activity which simply set the thingy visibility to visible so i get the admin screen.
Here is what you (@) asked for:
