我要求提供电子邮件、user_birthday 和姓名。每次登录 Web 视图出现时，它只列出基本信息。

它似乎与 onClickLogin 侦听器中对 openActiveSession 的调用有关。

此类是“SessionLoginSample”facebook 示例项目的“LoginUsingActivityActivity.java”文件的复制/粘贴。我添加的唯一内容是权限、关闭会话 onStart 和 onStop，以及在 SessionStatusCallback 中添加检索用户信息的请求。

我无法找到权限未显示在授权对话框中的原因。非常感谢任何帮助，代码粘贴在下面。

您可以使用以下代码添加所需的权限

  session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback).setPermissions(Arrays.asList("email", "user_status")));
