Why is the container null for static fragment?

I have the following Layout with static fragment and RelativeLayout as parent:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="@dimen/activity_vertical_margin">

    <fragment
        android:id="@+id/list_fragment"
        android:name="com.listfragmenttest.MyListFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout>

Yet the container or parent comes up null in OnCreateView:

public class MyListFragment extends ListFragment {

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

Is this the normal behavior for Static fragment?

Yes, that's how it is implemented. Fragments inflated statically from XML get a null as parent container.

For details, consult FragmentManager source. In particular, onCreateView() that handles fragment instantiation from layout inflation, setting mInLayout = true and calls to performCreateView() that are conditional on mInLayout.
