use this fragment_Jobqueue.xml: 
<ListView 
    android:id="@android:id/list" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:dividerHeight="0.1dp" 
    android:divider="#0000CC"> 

</ListView>

братан прикрепить этот код в на резюме

JobQueueFragment.java 


@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 


    return inflater.inflate(R.layout.fragment_jobqueue, container, false);

Если я изменить его фрагмент, то setListAdapter даст ошибку говоря – user3479916

метод не определен для этого фрагмента – user3479916

измените его с помощью mainListView.setAdapter (адаптер); –
