Try removed **andorid** from the code `list_View = (ListView) groupFragmentView.findViewById(android.R.id.list_View);`. If ListView is defined by you in the layout, then it is **R.id.list_View**. If that doesn't fix your problem, then post your layout, **fragment_group.xml**. — i_A_mok, Nov 20 '20 at 10:17
Give id to ListView, so add `android:id="@+id/list_View"` inside ListView tag. — i_A_mok, Nov 20 '20 at 10:57

You have to pass the object of view in your method.

@Override public View onCreateView(LayoutInflater inflater, 
      ViewGroup container, Bundle savedInstanceState) { 
    // Inflate the layout for this fragment
    groupFragmentView=inflater.inflate(R.layout.fragment_group,container,false); 
    InitializeFields(groupFragmentView);
    return groupFragmentView;
}

private void InitializeFields(View view)
{
    list_View =  (ListView) view.findViewById(android.R.id.**list_View**);}
