How can I access getSupportFragmentManager() in a fragment?

You can directly call

getFragmentManager() 

to get the fragment manager.

or

In your fragment,

Create field :

private FragmentActivity myContext;

override onAttach method of your fragment :

@Overridepublic void onAttach(Activity activity) {    myContext=(FragmentActivity) activity;    super.onAttach(activity);}

When you need to get Support fragment manager call :

FragmentManager fragManager = myContext.getSupportFragmentManager(); //If using fragments from support v4

or

FragmentManager fragManager = myContext.getFragmentManager();

You are done.

All you need to do is using

getFragmentManager()

method on your fragment. It will give you the support fragment manager, when you used it while adding this fragment.

Fragment Documentation

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().
