کیا با recyclerView کار کردن؟

 Adapter :
public class AdapterList extends RecyclerView.Adapter<AdapterList.ViewHolder> {
    Item[] itemsStatic;

    public AdapterList(ArrayList<Item> it) {
        itemsStatic = new Item[it.size()];
        for(int i=0; i<it.size(); i++){
            itemsStatic[i] = it.get(i);
        }
    }

    //a Reference to Views
    public static class ViewHolder extends RecyclerView.ViewHolder{
        public static TextView txtItem;
        public static ImageView imgItem;
        public static LinearLayout lnlItem;
        public ViewHolder(View v){
            super(v);
            txtItem = (TextView) v.findViewById(R.id.txt_item);
            imgItem = (ImageView) v.findViewById(R.id.img_item);
            lnlItem = (LinearLayout) v.findViewById(R.id.lnl_item);
        }
    }

    //Create new views
    @Override
    public AdapterList.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_item,viewGroup,false);
        ViewHolder viewHolder = new ViewHolder(view);
        return viewHolder;
    }

    //Replace Content Of a View
    @Override
    public void onBindViewHolder(AdapterList.ViewHolder viewHolder, final int i) {
        viewHolder.txtItem.setText(itemsStatic[i].title);
        viewHolder.imgItem.setImageResource(G.c.getResources().getIdentifier(itemsStatic[i].image,"drawable",G.c.getPackageName()));
    }

    @Override
    public int getItemCount() {
        return itemsStatic.length;
    }
}

Activity :

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
        RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
        RecyclerView.Adapter adapter = new AdapterList(G.items);
        recyclerView.setLayoutManager(layoutManager);
        recyclerView.setAdapter(adapter);

اینم با آرایه ی داینامیک ولی همون مشکل هنوز پا برجاست.

ببینید، من از این کد استفاده میکنم. مشکلی هم ندارم.

کد اداپتر:

 public class AdapterRecyclerView extends RecyclerView.Adapter<AdapterRecyclerView.viewHolder>{
    Context context;
    private LayoutInflater inflater;
    public AdapterRecyclerView(Context context, List<Information> data){
        inflater=LayoutInflater.from(context);
        G.recyclerList= (java.util.ArrayList<Information>) data;
    }

    @Override
    public viewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
       View view = inflater.inflate(R.layout.adapter_recycler, parent, false);
        viewHolder holder = new viewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(viewHolder holder, final int position) {

        final LocationManager manager = (LocationManager) G.context.getSystemService(Context.LOCATION_SERVICE);

        Information current = G.recyclerList.get(position);
        holder.title.setText(current.p_uname);
        holder.desc.setText(current.p_desc);
        String url = current.p_logo;
        Log.e("LOG", "URL_IMAGE_UNIVERSAL: " + url);
        
        holder.btnProfile.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });

        holder.btnRouting.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               
            }
        });
    }


    @Override
    public int getItemCount() {
        return G.recyclerList.size();
    }

    class viewHolder extends RecyclerView.ViewHolder{
        TextView title;
        TextView desc;
        FrameLayout btnProfile;
        FrameLayout btnRouting;
        ImageView image;



        public viewHolder(View itemView) {
                super(itemView);
                title = (TextView) itemView.findViewById(R.id.txtTitle);
                desc = (TextView) itemView.findViewById(R.id.txtDesc);
                btnProfile = (FrameLayout) itemView.findViewById(R.id.btnProfile);
                btnRouting = (FrameLayout) itemView.findViewById(R.id.btnRouting);
                image = (ImageView) itemView.findViewById(R.id.imageView);


        }
    }
}

اینم کدی هست که اطلاعات رو از سرور میگیرم و با اداپتر RecyclerView ست میکنم:

توی onCreate:

  recyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
        LinearLayoutManager layoutManager = new LinearLayoutManager(G.context);
        recyclerView.setLayoutManager(layoutManager);

اینم AsyncTask برای دریافت اطلاعات از سرور:

   public class asyncRecyclerview extends AsyncTask<Void, Void, List<Information>> {

        protected void onPreExecute() {
            super.onPreExecute();
            dialog3 = ProgressDialog.show(G.currentActivity, "", "در حال بارگزاری...", true);
        }

        @Override
        protected List<Information> doInBackground(Void... params) {


            //Read URL For Receive Json Code
            String result = Webservice.readUrl(url);
            Log.i("LOG", "URLRESULT: "+ result);
            if (result != null) {
                try {
                    G.recyclerList.clear();
                    JSONArray jsonurl = new JSONArray(result);
                    for (int i = 0; i < jsonurl.length(); i++) {
                        JSONObject object = jsonurl.getJSONObject(i);
                        Information url = new Information();
                        String img_url = object.getString("p_logo");
                        url.p_logo = (G.ip + "images/" + img_url);
                        url.p_uname = object.getString("p_uname");
                        url.p_desc = object.getString("p_desc");
                        url.p_uid = object.getInt("p_uid");

                        G.recyclerList.add(url);
                    }
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
            return G.recyclerList;
        }

        @Override
        protected void onPostExecute(List<Information> result) {
            super.onPostExecute(result);
            //tarif va meghdar dehie RecyclerView

            adapter = new AdapterRecyclerView(G.context, result);
            recyclerView.setAdapter(adapter);
            recyclerView.setLayoutManager(new LinearLayoutManager(G.context));
            recyclerView.setLayoutManager(new LinearLayoutManager(G.currentActivity, LinearLayoutManager.HORIZONTAL, false));
            //end
            dialog3.dismiss();
        }

    }

و در آخر هم Async رو داخل onCreate اجرا میکنید

  new asyncRecyclerview().execute();

اینی که نوشتم به نظرم راحتترین روش پیاده سازی RecyclerView بود. 

مشکل پیدا شد :

همونطوری که آقای Hajhosseini فرموده بودند هیچکدام از ویو ها نباید استاتیک باشه و با تغییر کلاس ViewHolder به کد زیر مشکل حل شد ، از همه دوستان تشکر میکنم ، مخصوصا حسین احمدی (CodeMaster) که تلفنی راهنماییم کرد.

    public class ViewHolder extends RecyclerView.ViewHolder{
        TextView txtItem;
        ImageView imgItem;
        LinearLayout lnlItem;

        public ViewHolder(View v){
            super(v);
            txtItem = (TextView) v.findViewById(R.id.txt_item);
            imgItem = (ImageView) v.findViewById(R.id.img_item);
            lnlItem = (LinearLayout) v.findViewById(R.id.lnl_item);
        }
    }
