Заполните Textview данными Sqlite, используя Spinner

Question

Я хочу заполнить текстовые представления данными из SQLite в своей деятельности, когда я выбираю элемент в счетчике.

Не отображается ошибка, но текстовые представления также не заполняются.

активность

rate_type_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
        {
            @Override
            public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l)
            {
                switch(i) {
                    case 0:
                        ResidentialRate();
                        break;
                    case 1:
                        break;
                    default:
                        break;
                }            
            }

            @Override
            public void onNothingSelected(AdapterView<?> adapterView)
            {

            }
        });
    }


    public void ResidentialRate()
    {
        db = new DatabaseHelper(getApplicationContext());
        sqLiteDatabase = db.getReadableDatabase();
        Cursor cursor = db.ResidentialListDetails();
        if (cursor.moveToFirst()) {
            do {
                String GENERAL_SYSTEM_CHARGE = cursor.getString(1);
                String FRANC_BENEFIT_TO_HOST_COMM = cursor.getString(2);
                String TRANSMISSION_SYSTEM_CHARGE = cursor.getString(3);
                String TRANSMISSION_DEMAND_CHARGE = cursor.getString(4);
                String SYSTEM_LOSS_CHARGE = cursor.getString(5);
                String DISTRIBUTION_DEMAND_CHARGE = cursor.getString(6);
                String DISTRIBUTION_SYSTEM_CHARGE = cursor.getString(7);

                gen_system_charge.setText(GENERAL_SYSTEM_CHARGE);
                franc_benefit_to_host_comm.setText(FRANC_BENEFIT_TO_HOST_COMM);
                trans_system_chg.setText(TRANSMISSION_SYSTEM_CHARGE);
                trans_demand_chg.setText(TRANSMISSION_DEMAND_CHARGE);
                system_loss_chg.setText(SYSTEM_LOSS_CHARGE);
                distr_demand_chg.setText(DISTRIBUTION_DEMAND_CHARGE);
                distr_system_chg.setText(DISTRIBUTION_SYSTEM_CHARGE);

            }
            while (cursor.moveToNext());
        }
    }

класс для выбора данных

public class RateListTypeDetails
{
    public static abstract class rateListValues
    {
        public static final String TABLE_NAME = "Rate";
        public static final String RATE_TYPE = "type";
        public static final String GENERAL_SYSTEM_CHARGE = "gen_system_charge";
        public static final String FRANC_BENEFIT_TO_HOST_COMM = "franc_benefit_to_host_comm";
        public static final String TRANSMISSION_SYSTEM_CHARGE = "trans_system_chg";
        public static final String TRANSMISSION_DEMAND_CHARGE = "trans_demand_chg";
        public static final String SYSTEM_LOSS_CHARGE = "system_loss_chg";
        public static final String DISTRIBUTION_DEMAND_CHARGE = "distr_demand_chg";
        public static final String DISTRIBUTION_SYSTEM_CHARGE = "distr_system_chg";
    }
}

public Cursor ResidentialListDetails()
    {
        SQLiteDatabase sqLiteDatabase = this.getReadableDatabase();
        String [] projections = {RateListTypeDetails.rateListValues.GENERAL_SYSTEM_CHARGE,
                RateListTypeDetails.rateListValues.FRANC_BENEFIT_TO_HOST_COMM,
                RateListTypeDetails.rateListValues.TRANSMISSION_SYSTEM_CHARGE,
                RateListTypeDetails.rateListValues.TRANSMISSION_DEMAND_CHARGE,
                RateListTypeDetails.rateListValues.SYSTEM_LOSS_CHARGE,
                RateListTypeDetails.rateListValues.DISTRIBUTION_DEMAND_CHARGE,
                RateListTypeDetails.rateListValues.DISTRIBUTION_SYSTEM_CHARGE,

        String selection = RateListTypeDetails.rateListValues.RATE_TYPE+" LIKE ?";
        Cursor cursor = sqLiteDatabase.query(RateListTypeDetails.rateListValues.TABLE_NAME,projections, selection, null,null,null,null);
        return cursor;
    }

Я хочу, чтобы эти текстовые представления с подсказками заполнялись данными sqlite с использованием счетчика

Заранее спасибо.
