Swipe Refresh Layout in Android Fragment

Im essayant d'implémenter SwipeRefreshLayout sur un fragment.

Je l'ai déjà résolu pour l'implémenter sur une activité, mais quand je l'implémente sur Fragment: Java.lang.NoClassDefFoundError: com ...

Est-ce que quelqu'un a une idée? Merci!

Mon code:

public class Principal extends Fragment implements OnRefreshListener {
    SwipeRefreshLayout swipeLayout;

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

        // Inflate the layout for this fragment
        view = inflater.inflate(R.layout.principal, container, false);

        swipeLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_container);
        swipeLayout.setOnRefreshListener(this);
        swipeLayout.setColorScheme(Android.R.color.holo_blue_bright, 
                Android.R.color.holo_green_light, 
                Android.R.color.holo_orange_light, 
                Android.R.color.holo_red_light);

        return view;
    }
}

Et ma mise en page:

<Android.support.v4.widget.SwipeRefreshLayout
    xmlns:Android="http://schemas.Android.com/apk/res/Android"
    Android:id="@+id/swipe_container"
    Android:layout_width="match_parent"
    Android:layout_height="match_parent">

    <com.enhancedListView.EnhancedListView
        Android:id="@+id/listaNoticias"
        Android:layout_width="match_parent"
        Android:layout_height="wrap_content"
        Android:layout_marginLeft="6dp"
        Android:layout_marginRight="6dp"
        Android:layout_marginTop="5dp" >
    </com.enhancedListView.EnhancedListView>

</Android.support.v4.widget.SwipeRefreshLayout>

Mettez votre initialisation swipeLayout dans onViewCreated (vue View, bundle Bundle) au lieu de onCreateView (gonfleur LayoutInflater, conteneur ViewGroup, Bundle savedInstanceState)

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {

        swipeLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_container);
        swipeLayout.setOnRefreshListener(this);
        swipeLayout.setColorScheme(Android.R.color.holo_blue_bright, 
                Android.R.color.holo_green_light, 
                Android.R.color.holo_orange_light, 
                Android.R.color.holo_red_light);
}

Assurez-vous simplement que vous avez mis le code pour la mise à jour du balayage dans override fun onViewCreated(view: View, savedInstanceState: Bundle?) {} au lieu de onCreateView.
