AutoScrollLoopViewPager

Android auto scroll viewpager or viewpager in viewpager

1. Trinea/AutoScrollViewPager

• ViewPager which can auto scroll, cycle.

• ViewPager which can be slided normal in parent ViewPager.

2. yanzm/LoopViewPager

An android ViewPager extension allowing infinite scrolling.

we can get the real position:

int position = (CONTENT.length + position%CONTENT.length)%CONTENT.length;

The only thing you need to know that the position is not real position.

For example, is the data size if 4, and the page limit is 1, and the four pa . * at first, the index [-1, 0, 1] page will create * after fliping left 3 pages, the index [2, 3, 4] page will create. * real postion should be mapping realPosition = (count + position%count) % count, so index -1 will create the fourth page, and index 4 will create first page.
