CollapsingToolbarLayout leaving empty space below Recyclerview
I'm having this strange issue with CoordinatorLayout and RecyclerView.
As you can see in the image, the RecyclerView is leaving an empty blank space below it with the exact same height as declared for CollapsingToolbarLayout's minHeight attribute.
If I don't declare this attribute, the linear_navigation LinearLayout won't remain pinned to the top of the screen (and that's the desired behaviour).
I'm I missing something? Here's the layout's code and some screenshots.

Solution
Finally I've found a workaround for my situation. I don't know exactly why it works, but it does. If somebody knows why this is working, or even better, why is it happening, please answer the question and I will be happy to accept the answer as correct.
The workaround is placing an empty gone view below the RecyclerView. It's working for me!
