And because of that, the navigationView was not being opened over the status bar.Also, you have to keep in mind that FrameLayout (the container) will be replaced in Java code with ContainerFragment.java fragment.If you embed DrawerLayout inside other layout (let’s say a RelativeLayout as root view) and you place other UI components outside the DrawerLayout, those UI components will overlap the NavigationView when opened like below: In the image below, we have described the hierarchy of the views (which view contains which view).Īs you can see, DrawerLayout is the root view of this layout and this is the correct way to do it.
