android - 각 항목 행에 대해 recyclerview에서 textview 값을 얻는 방법

RecyclerView 가있다   Itemname 로 항목을 표시하는 곳 Itemrate 및+/-버튼으로 각각 증가 및 감소 된 항목의 수량입니다.

그러나 pyzwyz의 각 항목에서 모든 값을 가져오고 싶습니다.  서버로 보내거나 로컬 데이터베이스에 저장하여 어떻게 달성 할 수 있습니까?

이것은 내 RecyclerView 입니다  수업

Adapter

이것은 내 public class TeaListAdapter extends RecyclerView.Adapter<TeaListAdapter.MyViewHolder> { //private int num=0; private List<TeaListPOJO> teaItemList; private Context mContext; private Cursor cursor; int comboCount; HashMap<Object,Integer> selectedMap = new HashMap (); private String ItemName; private String itemrate; private String qty; public class MyViewHolder extends RecyclerView.ViewHolder { public TextView tvitemName, tvitemRate,tvcount; //number public ImageView ivItemImg,ivPlus,ivMinus; public Button btnIncrease,btnDecrease; RecyclerView.ViewHolder holder; public MyViewHolder(View view) { super(view); tvitemName = (TextView) view.findViewById(R.id.txt_item_name); tvitemRate = (TextView) view.findViewById(R.id.txt_item_price); ivItemImg= (ImageView) view.findViewById (R.id.iv_item); ivPlus=(ImageView) view.findViewById (R.id.row_view_final_order_iv_plus); ivMinus=(ImageView) view.findViewById (R.id.row_view_final_order_iv_minus); tvcount=(TextView) view.findViewById (R.id.row_view_final_order_tv_count); } } public TeaListAdapter(List<TeaListPOJO> teaItemList) { this.mContext=mContext; this.cursor=cursor; this.teaItemList = teaItemList; } @Override public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View itemView = LayoutInflater.from(parent.getContext()) .inflate(R.layout.rv_placeorder_items, parent, false); return new MyViewHolder (itemView); } @Override public void onBindViewHolder(final MyViewHolder holder, final int position) { TeaListPOJO tealist = teaItemList.get(position); holder.tvitemName.setText(tealist.getItemName ()); holder.tvitemRate.setText(AppConstants.INDIAN_RUPEE_SIGN.concat (tealist.getItemRate ())); holder.ivPlus.setOnClickListener (new View.OnClickListener () { @Override public void onClick(View view) { int count=0; try{ count = Integer.parseInt(holder.tvcount.getText().toString()); } catch(Exception e) { count = 0; } //count++; count = Integer.parseInt(holder.tvcount.getText().toString()); holder.tvcount.setText(String.valueOf(count+ 1)); } }); holder.ivMinus.setOnClickListener (new View.OnClickListener () { @Override public void onClick(View view) { int count=0; try{ count = Integer.parseInt(holder.tvcount.getText().toString()); } catch(Exception e) { count = 0; } if(count>0) { //count--; count = Integer.parseInt (holder.tvcount.getText ().toString ()); holder.tvcount.setText (String.valueOf (count - 1)); } } }); holder.itemView.setOnClickListener (new View.OnClickListener () { @Override public void onClick(View view) { } }); /* Intent intent = new Intent (mContext, PlaceOrderActivity.class); // intent.putExtra("quantity",Integer.parseInt(quantity.getText().toString())); intent.putExtra ("quantity", qty); intent.putExtra ("item", ItemName); intent.putExtra ("itemrate", itemrate); ItemName = holder.tvitemName.getText().toString(); qty = holder.tvcount.getText().toString(); itemrate=holder.tvitemRate.getText ().toString (); Log.e("rate",itemrate); Log.e("qty",qty);*/ byte[] decodedString = new byte[0]; try { decodedString = Base64.decode(tealist.getImageStr(), Base64.DEFAULT); // tenantModelPOJO.setLogo(decodedString); Bitmap bmp = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); holder.ivItemImg.setImageBitmap(Bitmap.createScaledBitmap(bmp, 50, 50,false)); } catch (Exception e) { e.printStackTrace(); } } @Override public int getItemCount() { return teaItemList.size(); } } 입니다  수업 :
