Recyclerview ne fait appel à aucune méthode D'adaptation: onCreateViewHolder,onBindViewHolder,

mon RecyclerView ne pas appeler onCreateViewHolder, onBindViewHolder, par conséquent, ne semble pas rien dans recyclerview. J'ai mis des logs pour le débogage, et aucun log n'est affiché. Ce qui peut être?

mon adaptateur:

public class CommentListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder>{
private static final int EMPTY_VIEW = 10 ;
private ArrayList<comment> mItems;
Boolean firstTime = true;
private Typeface mTf = null;
Context mContext;
public CommentListAdapter(Context context,ArrayList<comment> items){
    Log.e("Adapter", "constructor Called");
    this.mItems = items;
    mContext = context;
}
public class EmptyViewHolder extends RecyclerView.ViewHolder {
    public EmptyViewHolder(View itemView) {
        super(itemView);
    }
}
public class ViewHolder extends RecyclerView.ViewHolder{
    TextView mAuthorName;
    TextView mMessage;
    NetworkImageView mThumbnail;
    public ViewHolder(View itemView) {
        super(itemView);
        mAuthorName = (TextView)itemView.findViewById(R.id.author_name);
        mMessage = (TextView)itemView.findViewById(R.id.message);
        mThumbnail = (NetworkImageView)itemView.findViewById(R.id.author_avatar);
    }

}

public void add(comment item, int position) {
    mItems.add(position, item);
    notifyItemInserted(position);
}

public void remove(comment item) {
    int position = mItems.indexOf(item);
    mItems.remove(position);
    notifyItemRemoved(position);
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
    Log.e("Adapter", "onCreateViewHolder Called");
    View v;
    if(firstTime){
        mTf = BBcTypeFace.getTypeFace(parent.getContext().getApplicationContext(),"font/bbc.ttf");
        firstTime = false;
    }
    if( viewType == EMPTY_VIEW){
        v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.comment_empty_row,parent,false);
        EmptyViewHolder evh = new EmptyViewHolder(v);
        return evh;
    }else {
        v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.comment_row, parent, false);
        ViewHolder vh = new ViewHolder(v);
        return vh;
    }
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder viewHolder, int position) {
    Log.e("Adapter", "onBindViewHolder Called");
    if(viewHolder instanceof ViewHolder) {
        ViewHolder holder = (ViewHolder)viewHolder;
        comment c = mItems.get(position);
        Log.e("Adapter", "Comment isn: " + c.toString());
        final ViewHolder finalHolder = holder;
        ImageRequest request = new ImageRequest(c.author_img_link, new Response.Listener<Bitmap>() {
            @Override
            public void onResponse(Bitmap bitmap) {
                if (bitmap != null) {
                    finalHolder.mThumbnail.setImageBitmap(bitmap);
                }
            }
        }, 0, 0, null,
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError volleyError) {
                        VolleyLog.e("ImageLoader", volleyError.getMessage());
                        VolleyLog.e("ImageLoader", volleyError.getStackTrace());
                    }
                });
        GetVideoInfo.getInstance(mContext.getApplicationContext()).addToRequestQueue(request);
        holder.mAuthorName.setText(c.author_name);
        holder.mMessage.setText(c.Message);
        holder.mMessage.setTypeface(mTf);
        holder.mAuthorName.setTypeface(mTf);
    }
}
@Override
public int getItemCount() {
    Log.e("Adapter", "getItemCount() Called");
    return (mItems.size() > 0 ? mItems.size() : 1);
}
@Override
public int getItemViewType(int position) {
    Log.e("Adapter", "getItemViewType() Called");
    if (mItems.size() == 0) {
        return EMPTY_VIEW;
    }
    return super.getItemViewType(position);
}}

j'utiliserai public void add(comment item, int position){...} pour ajouter un article dans RecyclerView.

en Fragment:

private RecyclerView mRecyclerView;
private CommentListAdapter mAdapter;
private LayoutManager mLayoutManager;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_item_detail, container, false);
....

    mLayoutManager = new LinearLayoutManager(getActivity());
    mAdapter = new CommentListAdapter(getActivity(),new ArrayList<comment>());
    mRecyclerView = (RecyclerView)rootView.findViewById(R.id.comment_list);
    mRecyclerView.setHasFixedSize(true);
    mRecyclerView.setLayoutManager(mLayoutManager);
    mRecyclerView.setAdapter(mAdapter);
    mRecyclerView.setItemAnimator(new DefaultItemAnimator());

    makeJsonObjectRequest(mItem.url);
    return rootView;
}

je vais ajouter L'article à RecyclerView avec ce code:

JsonObjectRequest jsonObjReqComment = new
             JsonObjectRequest(Request.Method.GET,urlJsonObj+"#comment", null,
                     new Response.Listener<JSONObject>() {
                         @Override
                         public void onResponse(JSONObject response) {
                             try {
                                 JSONArray res = response.getJSONArray("response");
                                 //Log.e("Comment","Count:"+response.toString());
                                 //Log.e("Comment","Count:"+res.length());
                                 for (int i = 0; i < res.length(); i++) {
                                     JSONObject thread = res.getJSONObject(i);
                                     JSONObject author_json = thread.getJSONObject("author");

                                 }
