android - 在 Firebase 数据库中添加数据

Question

我正在迁移到 Firebase 以帮助我检索数据。我的问题是如何像下面的 JSON 一样格式化我的 Firebase 数据库数据。我如何指定像下面的 JSON 这样的对象？

您几乎可以将任何您喜欢的 JSON 直接写入 Firebase。不过，为了便于检索，您需要找出某种模式。我推荐如下内容:

doctors
  <docotrId>
    - doctorId
    - doctorName
    - specialisation
    - information
    - photo
    - phone
    - email
    - @healthCenter
healthCenters
  <healthCenterId>
    - centerId
    - name
    - @doctors[]
specialisationDoctors
  <specialisationName>
    <doctorId>

您需要做的第一件事是将您的数据映射到此模式。您可以创建 POJO 类、映射，甚至 JSON 格式的字符串。

然后在适当的节点上使用 setValue() 推送映射数据。请务必阅读 documentation获取更多信息。

您可能还想查看我正在开发的名为 Firebomb 的 Firebase 对象映射器(不要脸的插件)。 Android 版本即将推出。

最后使用适当的 Firebase event listeners 检索数据.
