I have coded for display method and modify method but it is not displaying and modify depending on username selected from spinner

What I have tried:

public List<SuperUserDetails> DisplayUserDetails(String accountName)
    {
        List<SuperUserDetails> userDetailList = new ArrayList<>();
        sqLiteDatabase = this.getReadableDatabase();
        String query = "SELECT "+USER_NAME+", "+USER_ADDRESS+", "+USER_DOB+", "+USER_PHONE+", "+USER_EMAIL+ ", "+USER_PASS+ ", "+USER_PASS+ " FROM "+USER_TABLE_NAME+" WHERE "+USER_UNAME+" = '"+accountName+"'";
        Cursor cursor = sqLiteDatabase.rawQuery(query, null);
        if (cursor.moveToFirst())
        {
            do
            {
                SuperUserDetails userDetails = new SuperUserDetails();
                userDetails.setName(cursor.getString(0));
                userDetails.setAddress(cursor.getString(1));
                userDetails.setDob(cursor.getString(2));
                userDetails.setPhone(cursor.getString(3));
                userDetails.setEmail(cursor.getString(4));
                userDetails.setPass(cursor.getString(5));
                userDetails.setPass(cursor.getString(6));
                userDetailList.add(userDetails);
            }while (cursor.moveToNext());
        }
        cursor.close();
        sqLiteDatabase.close();
        return userDetailList;
    }


    public boolean modifyUserDetails(SuperUserDetails modify) {
        SQLiteDatabase db = this.getWritableDatabase();
        ContentValues values = new ContentValues();
        String query = "select * from " +USER_TABLE_NAME;
        Cursor cursor = db.rawQuery(query, null);
        int count = cursor.getCount();
        //  values.put(USER_ID, count);
        values.put(USER_NAME, modify.getName());
        values.put(USER_ADDRESS, modify.getAddress());
        values.put(USER_DOB, modify.getDob());
        values.put(USER_PHONE, modify.getPhone());
        values.put(USER_EMAIL, modify.getEmail());
        // values.put(USER_UNAME, modify.getUname());
        values.put(USER_PASS,modify.getPass());
        //values.put(USER_TYPE, modify.getUtype());
       /* Cursor cursor1 = db.query(USER_TABLE_NAME, new String[] {USER_NAME,USER_ADDRESS,USER_DOB,USER_PHONE,USER_EMAIL,USER_PASS,USER_PASS},null,null,null,null,null,null,null);
        if(cursor1 != null) {
            cursor.moveToLast();
        }
        return cursor1;
        }*/

        /*db.query(USER_TABLE_NAME, null, "USER_UNAME = ?", new String[]{ " USER_UNAME"}, null,null,null,null,null,null,null);*/
        long modifyresult = db.update(USER_TABLE_NAME, values, USER_UNAME + " =?", new String[]{String.valueOf(modify.getUname())});
        if (modifyresult == -1)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
