How to reset viewpager content on Android?

I have changed to use FragmentStatePagerAdapter instead of FragmentPagerAdapter, the problem is resolved. Hope this helps.

I think the best solution to reload fragments in another fragment is :

@Override
public void onPause() {
    super.onResume();
    List<Fragment> fragments = getFragmentManager().getFragments();
    if (fragments != null) {
        FragmentTransaction fragmentTransaction  = getFragmentManager().beginTransaction();
        for (Fragment fragment : fragments) {
            if (fragment instanceof Fragment) {
                fragmentTransaction.remove(fragment);
            }
        }
        fragmentTransaction.commitNowAllowingStateLoss();
    }
}

Check for your use case whether commitNowAllowingStateLoss or commitAllowingStateLoss is necessary.
