Android:如何使用FirebaseAuth从Facebook获取更大的个人资料图片? [英] Android : How to get larger profile pic from Facebook using FirebaseAuth?

问题描述

我正在使用 FirebaseAuth 通过FB登录用户.这是代码:

I am using FirebaseAuth to login user through FB. Here is the code:

private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;
private CallbackManager mCallbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());

    // Initialize Firebase Auth
    mAuth = FirebaseAuth.getInstance();

    mAuthListener = firebaseAuth -> {
        FirebaseUser user = firebaseAuth.getCurrentUser();
        if (user != null) {
            // User is signed in
            Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid());
        } else {
            // User is signed out
            Log.d(TAG, "onAuthStateChanged:signed_out");
        }

        if (user != null) {
            Log.d(TAG, "User details : " + user.getDisplayName() + user.getEmail() + "\n" + user.getPhotoUrl() + "\n"
                    + user.getUid() + "\n" + user.getToken(true) + "\n" + user.getProviderId());
        }
    };
}

问题是我使用user.getPhotoUrl()获得的照片很小.我需要更大的图像，无法找到一种方法.任何帮助将不胜感激. 我已经尝试过了 通过Firebase登录获取更大的Facebook图像 但是，尽管它们是快速的，但是它不起作用，我认为API应该不会有所不同.

The issue is that the photo in I get from using user.getPhotoUrl() is very small. I need a larger image and can't find a way to do that. Any help would be highly appreciated. I have already tried this Get larger facebook image through firebase login but it's not working although they are for swift I don't think the API should differ.

推荐答案

无法从Firebase获取大于getPhotoUrl()提供的配置文件图片.但是，只要拥有用户的Facebook ID，Facebook图形就可以非常轻松地获取所需大小的用户个人资料图片.

It is not possible to obtain a profile picture from Firebase that is larger than the one provided by getPhotoUrl(). However, the Facebook graph makes it pretty simple to get a user's profile picture in any size you want, as long as you have the user's Facebook ID.

String facebookUserId = "";
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
ImageView profilePicture = (ImageView) findViewById(R.id.image_profile_picture);

// find the Facebook profile and get the user's id
for(UserInfo profile : user.getProviderData()) {
    // check if the provider id matches "facebook.com"    
    if(FacebookAuthProvider.PROVIDER_ID.equals(profile.getProviderId())) {
        facebookUserId = profile.getUid();
    }
}

// construct the URL to the profile picture, with a custom height
// alternatively, use '?type=small|medium|large' instead of ?height=
String photoUrl = "https://graph.facebook.com/" + facebookUserId + "/picture?height=500";

// (optional) use Picasso to download and show to image
Picasso.with(this).load(photoUrl).into(profilePicture);
