How to display an existing ListFragment in a DialogFragment

Question

I have the following problem:

I have an exisiting ListFragment, but I would like to display this as a dialog.

My first approach was to create a DialogFragment which has to ListFragment inside of it, but appearently it is currently not possible to put fragments in fragments.

Extending DialogFragment instead of ListFragment is also not possible, because of the heavy use of ListFragment methods.

Is there an easy way to do this?

What works for me is

1) in xml layout for your DialogFragment called, let's say, DialogFragmentwWithListFragment specify ListFragment class
E.g. dialog_fragment_with_list_fragment.xml :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <fragment
             android:id="@+id/flContent"
             android:layout_width="match_parent"
             android:layout_height="match_parent"
             android:padding = "10dp"
             class="com.xxx.yyy.DialogFragmentwWithListFragment " />
</LinearLayout>

2) in DialogFragmentwWithListFragment inflate dialog_fragment_with_list_fragment.xml

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.dialog_fragment_with_list_fragment, null);
}

3) invoke DialogFragmentwWithListFragment as regular DialogFragment:

 DialogFragmentwWithListFragment dialogFragment = DialogFragmentwWithListFragment  .newInstance();
 dialogFragment.setRetainInstance(true);
 dialogFragment.show(getFragmentManager(), "tag");

Hope, it helps.
