Well, this because you can't get access to FragmentManager of other Activity, and it`s absolutely normal.

You can simply commit second fragment to the same container as a first one (use single Activity) and use method setCustomAnimations(...) for your transaction to animation.

Good luck!

you can define another ListFragment in your Fragment like this:

SecondListFragment SecondListFragment= (SecondListFragment )getFragmentManager().findFragmentById(R.id.second_list_fragment);
SecondListFragment.SetupSecondFragmentList();//its written on onListItemClick in FirstFragment

SetupSecondFragmentList() is a function that setup a list view in my Second ListFragment which has called from first one
