ViewPager in a ListView - how to lock the scrolling axis?

Question

I have a ViewPager widget in every row of a ListView. This provides a shelf-like UI, so the user can scroll around searching for a shelf vertically, and then scroll horizontally

Answer 1

I've found a solution in this thread. There the problem is to handle touch events properly for a HorizontalScrollView inside a regular ScrollView, but the solution to that problem seems to apply to this one too.
