Question

在我的项目中，只有管理员可以将用户添加到firebase。在创建时，我想获得用户ID，因为我想在Firebase数据库中设置该用户的个人资料。

public void addNewFaculty(View view){
    String name,email,password,rePassword;
    name = txtname.getText().toString();
    email = txtEmail.getText().toString().trim();
    password = txtPassword.getText().toString().trim();
    rePassword = txtRepassword.getText().toString().trim();
    if(password.equals(rePassword))
    {
        Toast.makeText(this, "Password is not match", Toast.LENGTH_SHORT).show();
        return;
    }
    databaseReference= FirebaseDatabase.getInstance().getReference();
    firebaseUser = firebaseAuth.getCurrentUser();
    String id= firebaseUser.getUid();
    databaseReference = databaseReference.child("Profile").child(id);
    databaseReference.child("Name").setValue(name);
    // and some other things
    firebaseAuth.createUserWithEmailAndPassword(email,password)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if(task.isSuccessful()){
                        Toast.makeText(getApplicationContext(), "Employee Added Successfully", Toast.LENGTH_SHORT).show();
                    }else{
                        Toast.makeText(getApplicationContext(), "Please try Again", Toast.LENGTH_SHORT).show();
                    }
                }
            });

}

And want to set id here

当您在firebase auth中创建用户时，它会自动登录。因此，您可以在onComplete（）中获取您的ID，如果方法为：

    if(task.isSuccessful()){
       String id1 = firebaseAuth.getCurrentUser().getUid();
       //For adding into database

       databaseReference = databaseReference.child("Profile").child(id1);
       databaseReference.child("Name").setValue(name);

       Toast.makeText(getApplicationContext(), "Employee Added Successfully", Toast.LENGTH_SHORT).show();
    }else{
       Toast.makeText(getApplicationContext(), "Please try Again", Toast.LENGTH_SHORT).show();
    }

@Himashu Nain对这个问题的回答不正确。 firebaseAuth.getCurrentUser().getUid();将获得管理员的userId，因为该管理员已登录并且是当前用户。 @AtifRizwan希望创建员工帐户的userId（而不是管理员的！）。要获取所创建帐户的用户ID，您可以从完成监听器返回的任务中获取用户信息：即

 mAuth.createUserWithEmailAndPassword(email, password)
        .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
                Log.d(TAG, "createUserWithEmail:onComplete:" + task.isSuccessful());

                if (task.isSuccessful()) {
                    FirebaseUser user = task.getResult().getUser();

                    Log.d(TAG, "onComplete: uid=" + user.getUid());
                }
            }
        });
