Fragmenttransation Setcustomanimations Not Working

I trying to use the new android compatibility package to include fragments into my project. I am trying to include a transition animation when I add a new fragment. The thing is on

Solution 1:

This works in the current version of the library, but it was definitely broken previously. You can use something like this:

finalFragmentManagerfm= getSupportFragmentManager();
finalFragmentTransactionft= fm.beginTransaction();
ft.setCustomAnimations(R.anim.slide_up, R.anim.slide_down, R.anim.slide_up, R.anim.slide_down)
  .add(R.id.fragment_container, newSomeFragment(), FRAGMENT_TAG)
  .addToBackStack(FRAGMENT_TAG)
  .commit();

where R.anim.slide_up is your in animation and R.anim.slide_down is your out animation. The second pair of params (3 and 4) for setCustomAnimations allow you to specify the pop in/out animations for popping the backstack (e.g., when the user presses back, the fragment will animate away with the animation specified as the fourth param).

Solution 2:

I have found a workaround for this. Override onCreateAnimation(int transit, boolean enter, int nextAnim) in your fragment class then its working fine.

@Overridepublic Animation onCreateAnimation(int transit, boolean enter, int nextAnim) {
    return enter ? AnimationUtils.loadAnimation(getActivity(), R.anim.grow_fade_in_center) : AnimationUtils.loadAnimation(getActivity(), R.anim.shrink_fade_out_center);
}

Solution 3:

I am facing the same problem too, here's my situation:

1. I want to do some UI change after exit animation. but I found that exit animation didn't work. my UI change codes are in onBackPressed().

my solution is as following:

1. move UI change logic in onCreateAnimator(). and then exit animation works.

Solution 4:

Use the below example:

privatefungotoFragment(fragment:Fragment){
     parentFragmentManager.commit {
        setCustomAnimations(
             R.anim.slide_in,
           R.anim.fade_out,
              R.anim.fade_in,
             R.anim.slide_out
        )
         setReorderingAllowed(true)
        replace(R.id.fragment_dashboard_container, fragment)
        addToBackStack(null)
    }
}
