Android animated nested fragments

Question

I have an activity with a fragment A inside of it. The fragment A have nested fragment B inside of it. I'm switching B with C using following code:

            getChildFragmentManager()
                .beginTransaction()
                .setCustomAnimations(R.anim.move_left_in, R.anim.move_left_out,R.anim.move_right_in, R.anim.move_right_out)
                .replace(R.id.container, fragmentC)
                .addToBackStack("nested")
                .commit();

after that Im doing

        getChildFragmentManager().popBackStack();

what brings me back to fragment B. After that I switch fragment A with fragment D using code

        getSupportFragmentManager()
            .beginTransaction()
            .setCustomAnimations(R.anim.move_up_in, R.anim.move_up_out, R.anim.move_down_in, R.anim.move_down_out)
            .replace(R.id.fragment_holder, fragmentD)
            .addToBackStack("fragments")
            .commit();

and while that animation on A->D transaction is playing, the B plays animation of transaction C->B, and by poping backstack im getting same result, why?

I am not getting what you actually want. Can you elaborate a little bit on this part, "and while that animation on A->D transaction is playing, the B plays animation of transaction C->B, and by poping backstack im getting same result, why?"? — Zohaib Hassan, Jun 26 '17 at 21:12

When you switch fragment A with fragment D.

The content within fragment A detach from its parent and then transaction A -> D takes place,

Since you have already set animation to your fragments, delay due to those animation is the reason you,see that left out animation in B first, then A -> D animation.

Don't use the getChildFragmentManager(),

Use support fragmnetManager means use getSupportFragmentManager why?

Bcz of nested fragment

I hope your problem is solved with this solution. Thank you:)

Because I've also faced this problem while I'm doing animation with fragments, So, I just change it from child Manager to support manager so after that I get my results which I want. – Sejal Baraiya Jun 27 '17 at 09:27

and what about lifecycle? What if you rotate device, is fragment inside fragment recreated properly? – RadekJ Jun 27 '17 at 09:43
