NavigationDraw verändern

Hallo zusammen,
ich programmiere seit kurzem Android Apps.
Heute um 08:00 Uhr habe ich begonnen mit dem NavigationDrawer =>
https://developer.android.com/design/patterns/navigation-drawer.html

Jedoch habe ich richtig viele probleme. Wie kann ich den sch***s NavigationDrawer bearbeiten, entscheiden welche Optionen angezeigt werden sollen und welche nicht.

Mfg

Max
