问题描述
我正在使用电子邮件注册 Firebase.截至目前,他们无法在 Firebase 中设置 DisplayName.因此,我将用户重定向到一个课程,他们可以在通过电子邮件和密码注册后立即更改 DisplayName.
I am using email registration Firebase. As of now their is no option to set DisplayName in Firebase. So I am redirecting users to a class where they can change DisplayName soon after signing up through email and password.
我的问题是我无法做到这一点.这是我到目前为止所做的:
My problem is I am unable to achieve that. Here's what I have done so far:
public class UsernameActivity extends AppCompatActivity {
private FirebaseAuth.AuthStateListener authListener;
private FirebaseAuth auth;
private EditText mName;
private TextView btnSignUp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_username);
//get firebase auth instance
auth = FirebaseAuth.getInstance();
mName = (EditText) findViewById(R.id.name);
btnSignUp = (TextView) findViewById(R.id.sign_up_button);
final FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
btnSignUp.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
auth = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
}
if(user!=null)
{
UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
.setDisplayName(mName)
.build();
user.updateProfile(profileUpdates);
Intent intent = new Intent(UsernameActivity.this, JokeActivity.class);
startActivity(intent);
}
};
}
});
}}
下面是我想要实现的图像.
Below is the image of what I want to achieve.
推荐答案
你必须按照这个选项
@Override
protected void onStart() {
super.onStart();
firebaseAuth.addAuthStateListener(mAuthListener); //firebaseAuth is of class FirebaseAuth
}
@Override
protected void onStop() {
super.onStop();
if (mAuthListener != null) {
firebaseAuth.removeAuthStateListener(mAuthListener);
}
}
并在您的 OnCreate() 或 onCreateView() 中实现:
and in your OnCreate() or onCreateView() implment this:
firebaseAuth = FirebaseAuth.getInstance();
mAuthListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
if (!LoginFragment.displayName.isEmpty()) {
UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
.setDisplayName(LoginFragment.displayName).build();
user.updateProfile(profileUpdates).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Log.d("Display name: ", FirebaseAuth.getInstance().getCurrentUser().getDisplayName());
}
}
});
}
LoginFragment.displayName = "";
}
}
};
