[android-developers] ViewPager in a ListView - how to lock the scrolling axis?

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 amongst the contents of a
shelf. This works.

But the scrolling experience is terrible: if I start to drag a shelf's
ViewPager, scroll it horizontally, and accidentally drag a bit upwards/
downwards, then the ListView "traps" this dragging action, and start
to scroll vertically, ending my horizontal drag. In this state, the
drag action won't "return" to the ViewPager, the ListView has it, and
that's it. I have to start another drag action to affect the ViewPager
again. So I guess the ListView has precedence in these cases.

How can this be fixed? I'd like to achieve the exact opposite: If the
ViewPager inside a list row starts reacting to a horizontal drag, then
it should trap that action, and this drag should stop affecting the
ListView, no matter how the user moves his/her finger vertically. Can
this be done?
