public class DatabaseHandlerForBalance extends 

    SQLiteOpenHelper {
        SQLiteDatabase db;
        public static final String KEY_ID = "id";
        public static final String KEY_RubBalance = "rubBalance";

        private static final String DATABASE_NAME = "newUser";
        private static final String TABLE_NAME = "Balance";
        private static final int DATABASE_VERSION = 1;
        public DatabaseHandlerForBalance (Context context){
            super(context, DATABASE_NAME, null, DATABASE_VERSION);
        }

        @Override
        public void onCreate(SQLiteDatabase db) {
            String CREATE_BALANCE_TABLE = "CREATE TABLE " + TABLE_NAME + " ("
                    + KEY_ID + " INTEGER PRIMARY KEY, " + KEY_RubBalance +
                    " INTEGER, " + KEY_DollarBalance + " INTEGER " + ")";
            db.execSQL(CREATE_BALANCE_TABLE);
        }

        @Override
        public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
            db.execSQL("DROP TABLE IF EXISTS" + TABLE_NAME);
            onCreate(db);
        }
        BalanceTable getBalance(int id) {
            SQLiteDatabase db = this.getReadableDatabase();

            Cursor cursor = db.query(TABLE_NAME, new String[]{KEY_ID,
                            KEY_DollarBalance, KEY_RubBalance}, KEY_ID + "=?",
                    new String[]{String.valueOf(id)}, null, null, null, null);
            if (cursor != null)
                cursor.moveToFirst();

            BalanceTable balanceTable = new BalanceTable(Integer.parseInt(cursor.getString(0)),
                    Integer.parseInt(cursor.getString(1)), Integer.parseInt(cursor.getString(2)));
            // return contact
            return balanceTable;
        }
        public boolean updateDollarBalance(int rowId, int addToDollarBalance) {
           BalanceTable myTableOfUser = getBalance(rowId);
            ContentValues args = new ContentValues();
            args.put(KEY_DollarBalance, myTableOfUser.getDollarBalance()+addToDollarBalance);
            return db.update(DATABASE_NAME, args, KEY_ID + "=" + rowId, null) > 0;
        }
        public void addBalance(BalanceTable balanceTable){
            SQLiteDatabase db = this.getWritableDatabase();
            ContentValues values = new ContentValues();
            values.put(KEY_DollarBalance,balanceTable.getDollarBalance());

            db.insert(TABLE_NAME, null, values);
            db.close();
        }
    }
