I didn't add any view when activity's 'initialize time'. So there are no any views in VerticalPager.

Will be interest to implement a possibility to jump the pages.
Today, ViewPager work like this:
[1] -> [2] -> [3]

We need recreate this:
[1] -> [3] -> [2]

Stack the fragments will be a good ideia. What do you thinks?
[1] -> [n]

Hi Alex thanks for this very nice library
I use your library and I want to set current item programmatically.
for that I use this code:
horizontalViewpager.setCurentitem(horizontalViewpager.getCurentItem()+3);
but it's not working and my app going to not responding page in android.
is there any way to go to a page programmatically?
