从Firebase身份验证获取更新的用户 [英] Get updated User from Firebase Authentication

问题描述

我目前正在使用Firebase。目前，我正在使用 com.google.firebase：firebase-auth：10.0.1

创建用户，登录工作就像一个魅力。

现在我想为用户添加一个选项，用户可以更改他/她的displayName和profileImage

活动AI通过点击一个按钮来调用这个方法：

  public void updateFirebaseUser（String newDisplayName，Uri newPhotoUri）{
 final FirebaseAuth auth = FirebaseAuth.getInstance（）; 
 final FirebaseUser user = auth.getCurrentUser（）; 
 if（user == null ||（TextUtils.isEmpty（newDisplayName）& newPhotoUri == null））{
 return; 
 
 UserProfileChangeRequest.Builder builder = new UserProfileChangeRequest.Builder（）; $！
 $ b if（！TextUtils.isEmpty（newDisplayName））{
 builder.setDisplayName（newDisplayName）; 
} 
 if（newPhotoUri！= null）{
 builder.setPhotoUri（newPhotoUri）; 
} 
 UserProfileChangeRequest request = builder.build（）; 
 user.updateProfile（request）
 .addOnCompleteListener（new OnCompleteListener< Void>（）{
 @Override 
 public void onComplete（@NonNull Task< Void> task）{
 Toast.makeText（context，profile update success =+ task.isSuccessful（），
 Toast.LENGTH_SHORT）
 .show（）; 
} 
}）; 
 
 
 
 $ b $ p 
 $ b一切似乎都奏效，因为我在屏幕上收到Toast， profile update success = true 
 
 
 
稍后在应用程序中，我要显示用户信息， code> fillUserViews（）在活动B中。但仍旧显示我的旧信息。 p>  private void fillUserViews（NavigationView navigationView）{
 View headerView = navigationView.getHeaderView（0）; 
 FirebaseAuth auth = FirebaseAuth.getInstance（）; 
 FirebaseUser user = auth.getCurrentUser（）; 
 
 ImageView avatarVIew =（ImageView）headerView.findViewById（R.id.img_avatar）; 
 picasso.load（user.getPhotoUrl（））
 .into（avatarVIew）; 
 
 TextView userName =（TextView）headerView.findViewById（R.id.txt_name）; 
 userName.setText（user.getDisplayName（））; 
 
 TextView userMail =（TextView）headerView.findViewById（R.id.txt_mail）; 
 userMail.setText（user.getEmail（））; 
 
 $ / code $ / pre 
 
 
重新启动应用程序在这里没有帮助。但是，如果我注销并再次登录我的用户数据更新。 我认为这与Firebase内部缓存有关。这就是为什么在显示敬酒之后添加了这行 auth.getCurrentUser（）。reload（）; 。
 
 
是否有可能强制更新请求到Firebase？ 
 
 
在此先感谢！
解决方案
 wuhuuuu！我发现了一个解决方案：
 
 
我正在重新加载用户对象，当我非常需要它，请求成功后，我正在更新我的视图！
  private void fillUserViews（NavigationView navigationView）{
 final查看headerView = navigationView.getHeaderView（0）; 
 final FirebaseAuth auth = FirebaseAuth.getInstance（）; 
 auth.getCurrentUser（）
 .reload（）
 .addOnSuccessListener（new OnSuccessListener< Void>（）{
 $ b $ @Override 
 public void onSuccess void aVoid）{
 FirebaseUser user = auth.getCurrentUser（）; 
 
 ImageView avatarVIew =（ImageView）headerView.findViewById（R.id.img_avatar）; 
 picasso.load user.getPhotoUrl（））
 .into（avatarVIew）; 
 TextView userName =（TextView）headerView.findViewById（R.id.txt_name）; 
 userName.setText（user.getDisplayName（） ）; 
} 
}）; 
} 
  
 
I'm currently working with Firebase. At the moment I'm using com.google.firebase:firebase-auth:10.0.1


Creating a user, Sign-In works like a charm.

Now I want to add an option for the user where it's possible for the user to change his/her displayName and profileImage

In Activity A I call this method, by clicking a button: 
   public void updateFirebaseUser(String newDisplayName, Uri newPhotoUri) {
      final FirebaseAuth auth = FirebaseAuth.getInstance();
      final FirebaseUser user = auth.getCurrentUser();
      if (user == null || (TextUtils.isEmpty(newDisplayName) && newPhotoUri == null)) {
         return;
      }
      UserProfileChangeRequest.Builder builder = new UserProfileChangeRequest.Builder();

      if (!TextUtils.isEmpty(newDisplayName)) {
         builder.setDisplayName(newDisplayName);
      }
      if (newPhotoUri != null) {
         builder.setPhotoUri(newPhotoUri);
      }
      UserProfileChangeRequest request = builder.build();
      user.updateProfile(request)
            .addOnCompleteListener(new OnCompleteListener<Void>() {
               @Override
               public void onComplete(@NonNull Task<Void> task) {
                  Toast.makeText(context, "profile update success = " + task.isSuccessful(),
                        Toast.LENGTH_SHORT)
                        .show();
               }
            });
   }
Everything seems to work, because I receive the Toast on my screen, which shows "profile update success = true"

Later in the app I want to display the user info, I call fillUserViews() in Activity B. But still my old information is displayed. 
   private void fillUserViews(NavigationView navigationView) {
      View headerView = navigationView.getHeaderView(0);
      FirebaseAuth auth = FirebaseAuth.getInstance();
      FirebaseUser user = auth.getCurrentUser();

      ImageView avatarVIew = (ImageView) headerView.findViewById(R.id.img_avatar);
      picasso.load(user.getPhotoUrl())
            .into(avatarVIew);

      TextView userName = (TextView) headerView.findViewById(R.id.txt_name);
      userName.setText(user.getDisplayName());

      TextView userMail = (TextView) headerView.findViewById(R.id.txt_mail);
      userMail.setText(user.getEmail());
   }
Also restarting the app doesn't help here. But if I logout and re-login again my user data is updated. 

I think this has something to do with the Firebase internal caching. That's why I added this line auth.getCurrentUser().reload(); after showing the the toast.

Is there a possibility to force the update-request to Firebase? I found nothing in the documentation.

Thanks in advance!
解决方案
wuhuuuu! I found a solution:

I'm reloading the user object when I acutally need it and after the request was successful I'm updating my views!
   private void fillUserViews(NavigationView navigationView) {
      final View headerView = navigationView.getHeaderView(0);
      final FirebaseAuth auth = FirebaseAuth.getInstance();
      auth.getCurrentUser()
            .reload()
            .addOnSuccessListener(new OnSuccessListener<Void>() {

               @Override
               public void onSuccess(Void aVoid) {
                  FirebaseUser user = auth.getCurrentUser();

                  ImageView avatarVIew = (ImageView) headerView.findViewById(R.id.img_avatar);
                  picasso.load(user.getPhotoUrl())
                        .into(avatarVIew);
                  TextView userName = (TextView) headerView.findViewById(R.id.txt_name);
                  userName.setText(user.getDisplayName());
               }
            });
   }
