Replacing ViewPager with Fragment – Then Navigating Back

by

I also had this very same problem for a long time. The solution turns out to be very simple, and you don’t need any hacks with the ViewPager Visibility. I is described in this other SO related question: Fragment in ViewPager not restored after popBackStack

However, to make it simple, all you need is to use getChildFragmentManager() in your ViewPager adapter, instead of getSupportFragmentManager(). So, instead of this:

    /** Getting fragment manager */
    FragmentManager fm = getSupportFragmentManager();

    /** Instantiating FragmentPagerAdapter */
    MyFragmentPagerAdapter pagerAdapter = new MyFragmentPagerAdapter(fm);

    /** Setting the pagerAdapter to the pager object */
    mViewPager.setAdapter(pagerAdapter);

You do this:

    /** Getting fragment manager */
    FragmentManager fm = getChildFragmentManager();

    /** Instantiating FragmentPagerAdapter */
    MyFragmentPagerAdapter pagerAdapter = new MyFragmentPagerAdapter(fm);

    /** Setting the pagerAdapter to the pager object */
    mViewPager.setAdapter(pagerAdapter);
