How do I programmatically add this fragment to my fragment?

Question

I am trying to display a nested ListFragment inside my DialogFragment.

Apparently I cannot just declare a <fragment> in the XML for my DialogFragment layout because fragments-in-fragments need the childFragmentManager. So I am trying to do this in my DialogFragment:

Fragment listfragment = new ClassThatExtendsListFragment();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(????????, listfragment).commit();

I have absolutely no idea what resource ID I need to put in the ???????? section, or how I'd even go about assigning it.

simply add FrameLayout in you layout. suppose you gave it's id as "container",

Fragment exampleFragment = new ExampleFragment();
    getSupportFragmentManager().beginTransaction()
            .add(R.id.container, exampleFragment).commit();
