Question

我正在使用最近的Fb SDK。我在Android Studio中进行fb集成。我已经完成了fb docs的所有步骤。但是在通过fb成功登录后我没有收到电子邮件ID。

这是我的MainActivity.java

设置，gradle这个

include ':app', ':facebook-android-sdk-4.7.0'

Answer 2

使用我的代码更改onClickListener的部分：

btnLoginFb.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {

    @Override
    public void onSuccess(LoginResult loginResult) {

        System.out.println("onSuccess");
        progressDialog = new ProgressDialog(LoginActivity.this);
        progressDialog.setMessage("Procesando datos...");
        progressDialog.show();
        String accessToken = loginResult.getAccessToken().getToken();
        Log.i("accessToken", accessToken);

        GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {

            @Override
            public void onCompleted(JSONObject object, GraphResponse response) {
                Log.i("LoginActivity", response.toString());
                // Get facebook data from login
                Bundle bFacebookData = getFacebookData(object); 


                }
            }
        });
        Bundle parameters = new Bundle();
        parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook
        request.setParameters(parameters);
        request.executeAsync();
    }

    @Override
    public void onCancel() {
        System.out.println("onCancel");
    }

    @Override
    public void onError(FacebookException exception) {
        System.out.println("onError");
        Log.v("LoginActivity", exception.getCause().toString());
    }
});

private Bundle getFacebookData(JSONObject object) {

    try {
        Bundle bundle = new Bundle();
        String id = object.getString("id");

        try {
            URL profile_pic = new URL("https://graph.facebook.com/" + id + "/picture?width=200&height=150");
            Log.i("profile_pic", profile_pic + "");
            bundle.putString("profile_pic", profile_pic.toString());

        } catch (MalformedURLException e) {
            e.printStackTrace();
            return null;
        }

        bundle.putString("idFacebook", id);
        if (object.has("first_name"))
            bundle.putString("first_name", object.getString("first_name"));
        if (object.has("last_name"))
            bundle.putString("last_name", object.getString("last_name"));
        if (object.has("email"))
            bundle.putString("email", object.getString("email"));
        if (object.has("gender"))
            bundle.putString("gender", object.getString("gender"));
        if (object.has("birthday"))
            bundle.putString("birthday", object.getString("birthday"));
        if (object.has("location"))
            bundle.putString("location", object.getJSONObject("location").getString("name"));

        return bundle;
    }

不要忘记查看此行以获得更好的结果：

parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook

试试这个对我有用的希望所以它也适合你

在您的主Activity或使用FaceBookSignIn方法

的活动中调用此方法

FacebookSdk.sdkInitialize(MainActivity.this);

在您的活动中添加此方法

public void FaceBookSignIn() {
    callbackManager = CallbackManager.Factory.create();
    loginType = Constants.loginTypeFaceBook;

    LoginManager.getInstance().logInWithReadPermissions(MainActivity.this, Arrays.asList("email", "user_photos", "public_profile"));
    LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            DisplaySnackBar.display(getWindow().getDecorView().findViewById(android.R.id.content), "Success", true);

            GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject jsonObject, GraphResponse graphResponse) {

                    try {
                            String email = jsonObject.getString(Constants.FacebookEmail),
                            String name = jsonObject.getString(Constants.FacebookName),
                            String firstName = jsonObject.getString(Constants.FacebookFirstName),
                            String lastName = jsonObject.getString(Constants.FacebookLastName),
                            String id = jsonObject.getString(Constants.FacebookID);
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,first_name,last_name,birthday,email");
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel() {
            DisplaySnackBar.display(getWindow().getDecorView().findViewById(android.R.id.content), "Sign In Cancel", true);
        }

        @Override
        public void onError(FacebookException e) {
            DisplaySnackBar.display(getWindow().getDecorView().findViewById(android.R.id.content), "Error", true);
        }
    });

}
