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:

This one edit profile activity: `private void updateUserInfo(final String weight, final String height, final FirebaseUser currentUser) {
/*Glide.with(this).load(currentUser.getPhotoUrl()).into(userImage);*/
mAuth.updateCurrentUser(currentUser).addOnCompleteListener(this, new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
UserProfileChangeRequest profileUpdate = new UserProfileChangeRequest.Builder()
.build();
currentUser.updateProfile(profileUpdate)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if(task.isSuccessful()){
UserProfile user = new UserProfile (
weight,
height
);
FirebaseDatabase.getInstance().getReference("Users Profile")
.child(FirebaseAuth.getInstance().getCurrentUser().getUid())
.setValue(user).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
//progressBar.setVisibility(View.GONE);
if (task.isSuccessful()) {
//acc successfully registered
showMessage("Account Updated");}
else{
}
}
});
}
}
});
最佳答案
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。
