Translucent/Transparent status bar + CoordinatorLayout + Toolbar + Fragment

Question

I have following setup:

• I\'m using AppCompat
• MainActivity, that holds a fragment and has a toolbar, that\'s hiding when scrolling down

Answer 1

For me, the reason was not that it did not work per se, but that I use the material drawer library from Mike Penz and this library does use fullscreen + offset + custom background behind the toolbar so I had to solve the problem respecting that special setup...

I'll reward the points to the in my opinion most informative answer though...
