FragmentTransaction animation to slide in over top

Question

I am trying to achieve the following effect using FragmentTransaction.setCustomAnimations.

1. Fragment A is showing
2. Replace Fragment A with Fragment B. F

Answer 1

After more experimentation (hence this is my second answer), the problem seems to be that R.anim.nothing means 'disappear' when we want another animation that explicitly says 'stay put.' The solution is to define a true 'do nothing' animation like this:

Make file no_animation.xml:

Now simply do as you would otherwise:

getActivity().getSupportFragmentManager().beginTransaction()
                .setCustomAnimations(R.anim.slide_in_right, R.anim.no_animation)
                .replace(R.id.container, inFrag, FRAGMENT_TAG)
                .addToBackStack("Some text")
                .commit();
