            ResponseString.setLoginId(data.res.rows.UserId);
            ResponseString.setLoginPassword(data.res.rows.Password);
            this.isChecked = true;
            this.userValue = ResponseString.getLoginId();
            this.pwdValue = ResponseString.getLoginPassword();

          } else{
