Recyclerview pas appeler n'importe quel Adaptateur méthode :onCreateViewHolder,onBindViewHolder,

mon RecyclerView ne pas appeler onCreateViewHolder, onBindViewHolder, par conséquent, ne semble pas rien dans recyclerview. J'ai mis les journaux de débogage, et aucun journal n'est montré. 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 is\n: " + 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);
}}

Je vais utiliser public void add(comment item, int position){...} pour ajouter un élément dans RecyclerView.

du 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;
}

Des Fichiers XML :

<ScrollView

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/scrollView"
android:background="@android:color/white"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true">
....
<RelativeLayout

android:layout_height="match_parent">

android:id="@+id/comment_list"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
....
</RelativeLayout>
....
</ScrollView>

comment_row fichier xml :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:orientation="horizontal"

Je vais ajouter un élément à la 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");
int dislikes = thread.getInt("dislikes");
int likes = thread.getInt("likes");
String Message = thread.getString("message");
//get Author info
String author_img_link = author_json.getJSONObject("avatar").getString("permalink");
String author_name = author_json.getString("name");
comment c = new comment(dislikes,likes,Message,author_img_link,author_name);
//Log.e("Comment",c.toString());
//commentsList.add(c);
mAdapter.add(c,0);
}
} catch (JSONException e) {
Log.e("OnResponse","Error JSON");
e.printStackTrace();
} catch (Exception e){
Log.e("OnResponse","Error Exception");
e.printStackTrace();
}
}
}
, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d("vOLLEY", "Error: " + error.getMessage());
//hide the progress dialog
}
}
){
@Override
public Map<String, String> getHeaders(){
Map<String, String> headers = new HashMap<String, String>();
headers.put("User-agent", "Comment");
return headers;
}
};
