I am trying to implement vertical swiping in my app. (Its just like the swiping with ViewPager, but vertically).
I found Jake Whartons library Android-DirectionalVie
Update (Feb 1st 14): This library is a really good alternative. I'm currently using it in my project and it's working flawlessly. It's still being maintained and it's a very close modification of the standard ViewPager from support lib r19. Another advantage is, that you can easily integrate and resolve it via maven central, if you're using gradle.

Thanks to Oleg Vaskevich, I was able to compile a new and working directionalViewpager jar-file from the current git files and oleg's additions/fixes. I can confirm that it's working with the current support-lib v4 r11.

hopefully this will be useful to somebody :)
to add: I had an IllegalArgumentException in DirectionalViewPager.setAdapter(PagerAdapter adapter){...};. So I've modified and fixed, recompiled and uploaded the new jar.
