无法从Firebase

Question

这是来自firebase数据库的我的JSON：

      }
    },
    "password" : "ses",
    "username" : "ses"
  }
}


@Override
    public Map<String, Object> rateHotel(String name, double lat, double lon) {
        Map<String, Object> hotel = new HashMap<>();
        hotel.put("name", name);
        hotel.put("latit", lat);
        hotel.put("longit", lon);
        return hotel;
    }

    @Override
    public void addHotel(String name, double lat, double lon) {
        String uid = firebase.getAuth().getUid();
        final Firebase hotelsRef = new Firebase("https://josip-my-application.firebaseio.com/Users/" + uid + "/hotel/");
        hotelsRef.push().setValue(rateHotel(name, lat, lon));
        presenter.onSuccess(name, lat, lon);
    }

这就是我在数据库中推送酒店的方式。我登录后登录了用户的酒店列表。当我点击列表中的一家酒店时，我是一个新的活动，我想要编辑某个酒店的某些字段。

我应该如何查找，或者我应该使用哪个firebase网址来访问某个酒店密钥？

这就是我用来推动新酒店进入火堆的网址......它将新酒店带入酒店＆＃34;酒店＆＃34;现场并为每个新酒店生成钥匙。我怎样才能拿到那把钥匙？

Firebase userRef = new Firebase("https://josip-my-application.firebaseio.com/Users/");
String uid = stringObjectMap.get("uid").toString();
userRef = new Firebase("https://josip-my-application.firebaseio.com/Users/" + uid + "/hotel/);
