Can NestedScrollview and ConstraintLayout work together?

Question

I'm trying the new ConstraintLayout and it's really cool and simple. I tried to apply it in a NestedScrollview inside coordinate layout where ConstraintLayout is the parent of the NestedScrollView.

But it didn't work, and all views collapsed vertically. How can I solve this?

Answer 1

I might be late but adding android:fillViewport="true"in NestedScrollView should resolve the issue.
