Navigation Drawer Fragment cut off at top

I'm using the Navigation Drawer Template on android and I'm also using fragments. Whenever there is a fragment, the action cuts off the fragment's top. I haven't changed the default code other than adding in the fragment. How do you get the fragment to load below the action bar?

Answer

The FrameLayout needs to be below the Toolbar, and inside the CoordinatorLayout. Try to restructure like so.

Include the "main contents" in the DrawerLayout. Then add the FrameLayout after the AppBarLayout (or include other views if Fragments aren't needed).

The secret line that "pushes" down the FrameLayout is this line

app:layout_behavior="@string/appbar_scrolling_view_behavior"
