Question

我使用与facebook关联的解析会话登录了我的应用。当我尝试向Facebook分享帖子时，它会显示我再次登录的Facebook窗口。如果我已经登录，为什么会这样做呢？当我调用ShareDialog时，我检查并且AccessToken.getCurrentAccessToken（）不为null，因此存在会话。怎么了？

WelcomeActivity

public void initializeFacebookButton() {

    if (AccessToken.getCurrentAccessToken() == null)
        ParseFacebookUtils.initialize(this);

    mLoginButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            progressBar.setVisibility(View.VISIBLE);
            ParseFacebookUtils.logInWithReadPermissionsInBackground(WelcomeActivity.this,
                    read_permissions, new LogInCallback() {
                        @Override
                        public void done(ParseUser user, ParseException e) {
                            progressBar.setVisibility(View.GONE);
                            if (e == null && user !=  null){
                                ParseFacebookUtils.linkWithPublishPermissionsInBackground(user,
                                        WelcomeActivity.this, publish_permission);
                                Log.d(TAG, "logged in");
                                   presenter.getUserFacebook(AccessToken.getCurrentAccessToken(),
                                        user);
                            } else {
                                Log.e(TAG, "Error logging in ");
                            }
                        }
                    });
        }
    });
}

ShareActivity

Button shareButton;

shareButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                ShareOpenGraphObject object = new ShareOpenGraphObject.Builder()
                .putString("og:type", "fitness.course")
                .putString("og:title", title)
                .putString("og:description", description)
                .putInt("fitness:duration:value", time_in_seconds)
                .putString("fitness:duration:units", "s")
                .putDouble("fitness:metrics:location:latitude", latitude)
                .putDouble("fitness:metrics:location:longitude", longitude)
                .build();
        ShareOpenGraphAction action = new ShareOpenGraphAction.Builder()
                .setActionType("fitness.runs")
                .putObject("fitness:course", object)
                .build();
        ShareOpenGraphContent content = new ShareOpenGraphContent.Builder()
                .setPreviewPropertyName("fitness:course")
                .setAction(action)
                .build();

                ShareDialog.show(ShareActivity.this, content);
            }
        });

Answer 1

在点击shareButton之前你有没有登出过某个地方？检查以下代码。

LoginManager.getInstance().logOut();

Answer 2

我认为你的问题是这个 -

logInWithReadPermissionsInBackground

您需要获得发布权限 - refer here

检查 - #{your div ID}{ background-image: url("backgroundImage.png"); }

Answer 3

根据你的代码，首先 logInWithReadPermissionsInBackground 将执行，Facebook show的弹出窗口要求阅读权限，然后另一个弹出窗口应该出现并要求发布权限 linkWithPublishPermissionsInBackground 会运行。那说你必须看到弹出并确认两次。

但我害怕这一点 ParseFacebookUtils.linkWithPublishPermissionsInBackground(user, WelcomeActivity.this, publish_permission); 正在执行，你打过电话 presenter.getUserFacebook(AccessToken.getCurrentAccessToken(), user); 它将用户导航到仪表板（或登录用户的任何页面），因此当前活动（保存并运行linkWithPublishPermissionsInBackground）将终止。我认为你应该替换

ParseFacebookUtils.linkWithPublishPermissionsInBackground(user,
                                    WelcomeActivity.this, publish_permission);
                            Log.d(TAG, "logged in");
                               presenter.getUserFacebook(AccessToken.getCurrentAccessToken(),
                                    user);

与

ParseFacebookUtils.linkWithPublishPermissionsInBackground(user, WelcomeActivity.this, publish_permission,new LogInCallback(){public void done(ParseUser user, ParseException e) {
 if (e == null && user != null) {
   Log.d(TAG, "logged in");
   presenter.getUserFacebook(AccessToken.getCurrentAccessToken(),user);
 }}});

Android Facebook分享按钮再次要求输入密码
