我想在我的 Android 应用程序中集成 Facebook 登录。我正在使用 Facebook-sdk-4.4.0。使用 LoginManager 类方法。但是我在运行以下代码时遇到问题-

FacebookSdk.sdkInitialize(getApplicationContext());    
callbackmanager = CallbackManager.Factory.create();

// Set permissions
LoginManager.getInstance().logInWithReadPermissions((Activity)getContext(), Arrays.asList("email", "public_profile"));

LoginManager.getInstance().registerCallback(callbackmanager,
        new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {

                GraphRequest request = GraphRequest.newMeRequest(
                        loginResult.getAccessToken(),
                        new GraphRequest.GraphJSONObjectCallback() {
                            @Override
                            public void onCompleted(JSONObject userInfo, GraphResponse graphResponse) {
                                try {
                                    FacebookClientController.setUserId(userInfo.optString(ID));
                                    FacebookClientController.setDisplayName(userInfo.optString(NAME));
                                    FacebookClientController.setEmailAddress(userInfo.optString(EMAIL));
                                    JSONObject picJson = userInfo.getJSONObject(PICTURE).getJSONObject("data");
                                    FacebookClientController.setProfilePicUrl(picJson.optString("url"));
                                    Log.d(LOGTAG, "\nUsername :" + FacebookClientController.getDisplayName());
                                    Log.d(LOGTAG, "\nEmail :" + FacebookClientController.getEmailAddress());
                                    Log.d(LOGTAG, "\nUserId :" + FacebookClientController.getUserId());
                                    Log.d(LOGTAG, "\nProfilePicUrl :" + FacebookClientController.getProfilePicUrl());
                                } catch (JSONException e) {
                                    Log.d(LOGTAG, "Json Error");
                                }
                            }
                        }
                );
                Bundle parameters = new Bundle();
                parameters.putString(FIELDS, FB_REQUEST_FIELDS);
                request.setParameters(parameters);
                GraphRequest.executeBatchAsync(request);

                Toast.makeText(getContext(), "Login successful" + loginResult.toString(), Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onCancel() {
                Log.d(LOGTAG, "On cancel");
            }

            @Override
            public void onError(FacebookException error) {
                Log.d(LOGTAG, error.toString());
            }
        });
}

我在我的应用程序中看到的是左侧屏幕，而不是运行上述代码时应该出现的右侧屏幕。谁能告诉我问题出在哪里？ 日志:

最佳答案

试试这个

LoginButton loginButton;
CallbackManager callbackManager;

FacebookSdk.sdkInitialize(getApplicationContext());
callbackManager = CallbackManager.Factory.create();

loginButton = (LoginButton) findViewById(R.id.login_button);
    loginButton.setReadPermissions(Arrays.asList("public_profile", "user_friends", "email"));

    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {

            Profile profile = Profile.getCurrentProfile();
            profile.getProfilePictureUri(315, 315);
            GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject object, GraphResponse response) {
                            Log.v("LoginActivity", response.toString());
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email");
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel() {
        }

        @Override
        public void onError(FacebookException e) {
            e.printStackTrace();
        }
    });

并覆盖下面的方法

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);         
}

并在 list 中定义

<activity
        android:name="com.facebook.FacebookActivity"            android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Translucent.NoTitleBar"/>
