Question

下面是我两项活动的代码。通过这样的编码，数据将被存储在firebase中。这是存储数据的快照：

这就是我得到的：

This is what I get

我想要的是这个

What I want is this

我知道发生这种情况是因为我对数据库有两个类，但是我尝试放入一个类，但是没有用。我认为是因为我的密码

下面是我的代码：

Answer 1

替换此：

 UserProfile user = new UserProfile (
       weight,
       height
 );

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

使用：

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)

如何将来自不同活动的数据保存到同一张表中？
