Question

我无法将用户的Facebook个人资料图片放入我的imageView。我想和Picasso图书馆联系。有想法解决这个问题吗？这是我的代码。提前谢谢！

R.string.facebook_provider_id =＆＃34; facebook.com＆＃34;

错误：

FATAL EXCEPTION: main
Process: com.example.yunus.ototakip, PID: 3045 java.lang.RuntimeException: Unable to start activity

ComponentInfo{com.example.yunus.ototakip/com.example.yunus.ototakip.Hesabim}: java.lang.IllegalArgumentException: Target must not be null.

Hesabim.java

public class Hesabim extends AppCompatActivity {

public FirebaseAuth firebaseAuth;
public FirebaseUser user;
public CircleImageView userImage;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_hesabim);
    userImage= (CircleImageView) findViewById(R.id.kullaniciHesapResmi);
    firebaseAuth = FirebaseAuth.getInstance();
    user = FirebaseAuth.getInstance().getCurrentUser();
    if(firebaseAuth.getCurrentUser()==null)
    {
        finish();
        startActivity(new Intent(this,Giris.class));
    }

    kullaniciMail.setText(firebaseAuth.getCurrentUser().getEmail());
    String facebookUserId = "";
    user = FirebaseAuth.getInstance().getCurrentUser();
    for(UserInfo profile : user.getProviderData()) {
        // check if the provider id matches "facebook.com"
        if(profile.getProviderId().equals(getString(R.string.facebook_provider_id))) {
            facebookUserId = profile.getUid();
        }
    }
    String photoUrl = "https://graph.facebook.com/" + facebookUserId + "/picture?type=medium";
    Picasso.with(this).load(photoUrl).into(userImage);

hesabim.xml

        <de.hdodenhof.circleimageview.CircleImageView
            android:id="@+id/kullaniciHesapResmi"
            android:layout_width="match_parent"

我希望你首先获得facebook的个人资料图片的许可，bcz未经许可facebook将不允许你获得任何东西。

loginButton.setReadPermissions("public_profile", "email", "user_friends", "user_education_history", "user_hometown", "user_likes", "user_work_history");

或者您也可以使用Facebook回调来获取用户个人资料图片，就像这样..

private FacebookCallback<LoginResult> mCallBack = new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(final LoginResult loginResult) {

            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(
                                JSONObject object,
                                GraphResponse response) {
                            Log.e("response: ", response + "");
                            try {
                                String id = object.getString("id").toString();
                                String email = object.getString("email").toString();
                                String name = object.getString("name").toString();
                                String profilePicUrl = "https://graph.facebook.com/" + loginResult.getAccessToken().getUserId() + "/picture?type=large";
                                Log.d("imageFB", profilePicUrl);
                                Log.d("FB_ID:", id);


                                checkFBLogin(id, email, name, profilePicUrl);

                            } catch (Exception e) {
                                e.printStackTrace();
                            }

                            finish();
                        }

                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender,birthday,friends,likes,hometown,education,work");
            request.setParameters(parameters);
            request.executeAsync();
        }

通过这种简单的解决方案，您可以获得高分辨率的个人资料图片：

如果您遵循Firebase示例，则在updateUI方法内部使用：

photoUrl = user.getPhotoUrl(); //here you get the picture

photoUrlstr = photoUrl.toString(); //here you store the link to quality

photoUrlstr = photoUrlstr + "?height=500"; //adjust quality

Glide.with(this).load(photoUrlstr).into(IVperfil); //put it in Imageview

希望它会有所帮助，因为这太简单了。
