How to Reverse Fragment Animations on BackStack?

Question

I thought the system would reverse animations on the backstack when the back button is pressed when using fragments using the following code:

FragmentManager         


        

Answer 1

.setCustomAnimations(R.animator.fragment_fade_in,
        R.animator.fragment_fade_out,
        R.animator.fragment_fade_p_in,
        R.animator.fragment_fade_p_out)

Replace the above with:

mFragmentManager.beginTransaction()
    .setCustomAnimations(R.animator.fragment_fade_in,
            R.animator.fragment_fade_out,
            R.animator.fragment_fade_p_in,
            R.animator.fragment_fade_p_out)
    .replace(R.id.main_container, FragmentPlayerInfo.getInstance(data))
    .addToBackStack(FragmentPlayerInfo.TAG)
    .commit();
