将数据插入实时数据库不起作用答案

【问题标题】：Insert data to Realtime Database does not works将数据插入实时数据库不起作用
【发布时间】：2021-03-30 00:43:15
【问题描述】：

我正在尝试创建一个应用程序，如果有人想使用我的应用程序，他们必须创建一个用户。当他们注册时，他们将插入名字、姓氏、电话和电子邮件地址。在我使用 Firebase 授权确认手机是他们的之后，我想将他的数据插入到我的实时数据库中名为 Users 的表中。

当我尝试使用此功能时：

**编辑：我添加了 onComplete 函数，但它没有执行 **

private void storeNewUserData() {
        FirebaseDatabase rootNode = FirebaseDatabase.getInstance();
        DatabaseReference reference = rootNode.getReference("Users");
        User user = new User(phone,firstName,lastName,email);
        reference.setValue(user).addOnCompleteListener(this);
    }


@Override
public void onComplete(@NonNull Task<Void> task) {
    if(task.isSuccessful()){
        Toast.makeText(this, "Inserted User: "+phone+firstName+lastName+email, Toast.LENGTH_SHORT).show();
    }
    else{
        Toast.makeText(this, task.getException().toString(), Toast.LENGTH_SHORT).show();
    }
}

数据库尚未更新，但出现了 Toast（包含所有数据）。

我认为我的代码没有问题，也许是我的 Firebase 帐户有问题。无论如何，我将规则添加到此数据库和表格图像中。

规则

{
  "rules": {
    ".read": "true",
        ".write": "true"
  }
}

build.gradle(app)

    mAuth.signInWithCredential(credential).addOnSuccessListener(new OnSuccessListener<AuthResult>() {
        @Override
        public void onSuccess(AuthResult authResult) {
            progressDialog.dismiss();
            User user = new User(phone,firstName,lastName,email);
            storeNewUserData();
            Toast.makeText(PhoneAuthActivity.this, "Logged in as "+phone, Toast.LENGTH_SHORT).show();
            startActivity(new Intent(PhoneAuthActivity.this, MainActivity.class));
        }


    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            progressDialog.dismiss();
            Toast.makeText(PhoneAuthActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });
}

P.S：我用的是安卓工作室

【问题讨论】：

您应该使用ValueEventListener 来跟踪特定节点/分支中的更改。
您是否尝试将完整的侦听器附加到 setValue() 方法？请回复@AlexMamo
@AlexMamo 我没试过请附上代码让我试试
@ShubhamPanchal 请附上代码，我可以试试
reference.setValue(user).addOnCompleteListener(/* ... */);

【解决方案1】：

我可以通过更改设备的互联网连接网络来解决此问题。该应用无法在移动数据上运行，但可以在其他设备的 WIFI 上运行。

问题背后的原因尚不清楚。
