I play in the design support library and run into a little problem and hope someone can help me.
I am using CollapsingToolbar, which contains an ImageView that collapses in parralax. In CollapsingToolbar, I have a TabLayout that should scroll through my ViewPager. My problem is that the ViewPager is not showing. The problem seems to only occur when I set my ViewPager View_ager layout to match_parent or wrap_content. If I set it to 600dp, the problem will disappear, but then the view will become a fixed length, which is not very nice.
Any help would be appreciated!
Here is my xml
