Fragments in backStack

1 answer

I have ViewPager that has 3 tabs. Tab(3) includes 2 fragments (A) --> (B).

Tab(1) Tab(2) Tab(3) --> (B) --> (C) 

The way I replace fragments in Tab(3):

FragmentTransaction trans = getActivity().getSupportFragmentManager().beginTransaction();             trans.replace(, new FragmentC().newInstance(), "C");             trans.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);             trans.addToBackStack("B->C");             trans.commit(); 

When I'm in (B) and I'm hitting a button it takes me straight to Tab(3), skipping (A). Here is the code from button in (B):

FragmentManager fm = getActivity().getSupportFragmentManager();             for(int i = 0; i < fm.getBackStackEntryCount(); ++i) {                 fm.popBackStack();             } 

Everything works good. The problem is when I'm in (B) but then I go to Tab(1) or Tab(2) and hit the button after it doesn't work. Please let me know what I'm doing wrong. Thank you.


I tried to replace etActivity().getSupportFragmentManager() with getChildFragmentMaganer(). Since the regular way of popBackStack() wasn't working anymore I had to modify it. Now it works and I have the same problem tho.

FragmentManager fm = getActivity().getSupportFragmentManager();             for (Fragment frag : fm.getFragments()) {                     FragmentManager childFm = frag.getChildFragmentManager();                     if (childFm.getBackStackEntryCount() > 0) {                         childFm.popBackStack();                     }                 }             }

The best answer:

Try using getChildFragmentManager() to get your fragment manager. From my experience, when i'm inside a fragment and i try to place another fragment inside it, I use getChildFragmentManager.
