User · Answer

Simply get it like this -  getFragmentManager      This will also give you the SupportFragmentManager or FragmentManager based on which Fragment class you have extended - android support v4 app Fragment OR android app Fragment    OR  getActivity   getSupportFragmentManager      in your Fragment s onActivityCreated   method and any method that is being called after onActivityCreated

User · Answer

You can use getActivity   getSupportFragmentManager   anytime you want to getSupportFragmentManager   hierarchy is Activity -  fragment  fragment is not capable of directly calling getSupportFragmentManger but Activity can   Thus  you can use getActivity to call the current activity which the fragment is in and get getSupportFragmentManager
