Geri dönüşümün görünümünde değer ve metin değeri nasıl kontrol edilir?

Question

Geridönüşümün metin ve değeri kontrol edilen öğenin değerini nasıl geri alabileceğimi açıklayabileceğimizi düşünebilirim. Burada, gereksinimimi açıkladığımı söyleyeyim sqlitedatabase ile geridönüşümün bağlayıcılığı her şey tamamdır ama kontrol edilen değeri ve kimliği bulamadım

Bu recyclerview için adaptör ayarlanır faaliyettir ve: Bu i recyclerview ayarlı adaptör olup

: ben bu beni şimdiye kadar ben neler yaptığımı kodunu paylaşmasına izin yok nasıl recyclerview onclick düğmesine değer almamız gerekir:

     statelist = account_sf_db.Statelist(); 

     // use this setting to improve performance if you know that changes 
     // in content do not change the layout size of the RecyclerView 
     mRecyclerView.setHasFixedSize(true); 

     // use a linear layout manager 
     mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); 

     // create an Object for Adapter 
     mAdapter = new CardViewDataAdapter(statelist); 

     // set the adapter object to the Recyclerview 
     mRecyclerView.setAdapter(mAdapter); 
     ok.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       List<Model_Account> stList = ((CardViewDataAdapter) mAdapter) 
         .getStudentist(); 
       String[] data = new String[stList.size()]; 
       Integer []ints=new Integer[stList.size()]; 
       for (int i = 0; i < stList.size(); i++) { 
        Model_Account singleStudent = stList.get(i); 
        if (singleStudent.isSelected()) { 


        //Here i need to pick the id and text of the checked value how can i do this!! 

        } 
       } 


      } 


     }); 
    } 
} 

}

Bu sqliteonehelper sınıftır: İşte bu aptal bir soru olabilir dal ile bir sonraki etkinliğe metin ve kimliği geçmesi gerekiyor ama

public List<Model_Account> Statelist() { 
     String countQuery = "SELECT * FROM " + Model_Account.spinner_state_table; 
     SQLiteDatabase db = this.getReadableDatabase(); 
     Cursor cursor = db.rawQuery(countQuery, null); 
     List<Model_Account>listobj = new ArrayList<Model_Account>(); 
     if (cursor.moveToFirst()) { 
      do { 
       Model_Account modelobj = new Model_Account(); 
       modelobj.setStateid(cursor.getInt(cursor.getColumnIndex(Model_Account._id))); 
       modelobj.setName(cursor.getString(cursor.getColumnIndex(Model_Account.StateName))); 
       modelobj.setStateid(cursor.getInt(cursor.getColumnIndex(Model_Account.PairlinkID))); 
       listobj.add(modelobj); 

      } while (cursor.moveToNext()); 
     } 
     cursor.close(); 
     db.close(); 
     return listobj; 


    }
