Est-il un addHeaderView équivalent pour RecyclerView?

Je suis à la recherche d'un équivalent de addHeaderView pour un recycleur de vue. Fondamentalement, je veux avoir une image avec 2 boutons-être ajouté comme en-tête de la liste. Est-il un autre moyen d'ajouter un en-tête de la vue à un recycleur de vue? Un exemple pour l'orientation serait utile

EDIT 2 (ajouté fragment de mises en page):

Après l'ajout du journal des déclarations, il semble que getViewType ne reçoit qu'une position de 0. Cela conduit à onCreateView que le chargement de la mise en page:

10-26 16:32:53.766    5449-5449/co.testapp I/logger info Adapter-> onBindViewHolder, viewType: 0

Le fragment de transition pour charger le CommentFragment:

@Override
public void onPhotoFeedItemClick(View view, int position) {
if (fragmentManager == null)
fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
if (view.getId() == R.id.button_comment){
CommentFragment commentFragment = CommentFragment.newInstance("","", position);
fragmentTransaction.add(R.id.main_activity, commentFragment,"comment_fragment_tag");
fragmentTransaction.addToBackStack(Constants.TAG_COMMENTS);
fragmentTransaction.commit();
}
}

Le Fragment de la onCreateView:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_comment, container, false);
mRecyclerView = (RecyclerView) view.findViewById(R.id.list_recylclerview);
mRecyclerView.setLayoutManager(new LinearLayoutManager(_context));
mRecyclerView.setItemAnimator(new DefaultItemAnimator());
mAdapter = new CommentAdapter(R.layout.row_list_comments, R.layout.row_header_comments, _context, comments);
mRecyclerView.setAdapter(mAdapter);
return view;
}

Le fragment contenant le recycleview:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:id="@+id/list_recylclerview"
android:layout_width="match_parent"
android:layout_height="200dp" />
</RelativeLayout>
</RelativeLayout>

La ligne commentaires mise en page:

L'en-tête

</LinearLayout>

Le code d'Adaptateur (grâce à hister de m'avoir commencé):

public class CommentAdapter extends RecyclerView.Adapter<ViewHolder>{
private final int rowCardLayout;
public static Context mContext;
private final int headerLayout;
private final String [] comments;
private static final int HEADER = 0;
private static final int OTHER = 0;
public CommentAdapter(int rowCardLayout, int headerLayout, Context context, String [] comments) {
this.rowCardLayout = rowCardLayout;
this.mContext = context;
this.comments = comments;
this.headerLayout = headerLayout;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
logger.i("onCreateViewHolder, viewtype: " + i); //viewtype always returns 0 so OTHER layout is never inflated
if (i == HEADER) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(headerLayout, viewGroup, false);
return new ViewHolderHeader(v);
}
else if (i == OTHER){
View v = LayoutInflater.from(viewGroup.getContext()).inflate(rowCardLayout, viewGroup, false);
return new ViewHolderComments(v);
}
else 
throw new RuntimeException("Could not inflate layout");
}
@Override
public void onBindViewHolder(ViewHolder viewHolder, int i) {
logger.i("onBindViewHolder, viewType: " + i);
if (viewHolder instanceof ViewHolderComments)
((ViewHolderComments) viewHolder).comment.setText(comments[i].toString());
if (viewHolder instanceof ViewHolderHeader)
((ViewHolderHeader) viewHolder).header.setImageResource(R.drawable.image2);
else {
logger.e("no instance of viewholder found");
}
}
@Override
public int getItemCount() {
int count = comments.length + 1;
logger.i("getItemCount: " + count);
return count;
}
@Override
public int getItemViewType(int position) {
logger.i("getItemViewType position: " + position);
if (position == HEADER)
return HEADER;
else
return OTHER;
}
public static class ViewHolderComments extends RecyclerView.ViewHolder {
public TextView comment;
public ImageView image;
public ViewHolderComments(View itemView) {
super(itemView);
comment = (TextView) itemView.findViewById(R.id.comment);
image = (ImageView) itemView.findViewById(R.id.image);
}
}
public static class ViewHolderHeader extends RecyclerView.ViewHolder {
public final ImageView header;
public ViewHolderHeader(View itemView){
super(itemView);
header = (ImageView) itemView.findViewById(R.id.header_photo);
}
}
}

L'aide du code ci-dessus, seule la mise en page d'en-tête est affiché comme viewType est toujours 0. Il ressemble à cette. Si je force la disposition d'autres il ressemble cette:
