java - 如何将不同 Activity 的数据保存到同一个表？

Question

下面是我的两项 Activity 的代码。通过这样的编码，数据像这样存储在 firebase 中。这是存储数据的快照:

这就是我得到的:

我想要的是这个

我知道发生这种情况是因为我有两个数据库类，但我尝试放入一个类，但没有成功。我认为这是因为我的代码

下面是我的代码:

Answer 1

替换这个:

 UserProfile user = new UserProfile (
       weight,
       height
 );

 FirebaseDatabase.getInstance().getReference("Users Profile")
       .child(FirebaseAuth.getInstance().getCurrentUser().getUid())
       .setValue(user)

与:

Map<String, Object> values = new HashMap<>();
values.put("height", height);
values.put("weight", weight);
FirebaseDatabase.getInstance().getReference("Users")
       .child(FirebaseAuth.getInstance().getCurrentUser().getUid())
       .updateChildren(values)

相关变更:

• 调用 updateChildren 而不是 setValue，因为 setValue 会替换您调用它的位置处的所有数据。
• 获取对 /Users 的引用，而不是 /Users Profile。

附加提示:考虑将高度和体重存储为数值，而不是字符串。否则，它们的排序/过滤将会变得困惑，因为 Firebase 对字符串使用字典顺序。
