Endless ViewPager android

Question

Let's say I have two pages in my viewpager, is it any way to move from page 2 to page 1, but doing this like user is accesing page 3 (with all the animation)

Answer 1

You can achieve this by using a custom FragmentPagerAdapter that provides the same fragments over and over again:

private class EndlessPagerAdapter extends FragmentPagerAdapter {

        private EndlessPagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {
            if (position % 2 == 0) {
                return fragmentOne;
            } else {
                return fragmentTwo;
            }
        }

        @Override
        public int getCount() {
            return Integer.MAX_VALUE;
        }
    }

Set the adapter for your ViewPager and start somewhere in the middle to allow almost endless swiping in either direction:

mViewPager.setAdapter(new EndlessPagerAdapter(getChildFragmentManager()));
mViewPager.setCurrentItem(Integer.MAX_VALUE/2);
