在android中从Facebook检索用户名和性别

概述这是我如何检索存储在共享首选项中的信息,然后比较用户名和密码是否存在.如果用户已登录,我可以显示其他活动. SharedPreferences settings = getSharedPreferences(“logindetails”,0); String username = settings.getString("username", ""); String password = 这是我如何检索存储在共享首选项中的信息,然后比较用户名和密码是否存在.如果用户已登录,我可以显示其他活动.

SharedPreferences settings = getSharedPreferences(“logindetails”,0);

String username = settings.getString("username","");    String password = settings.getString("password","");

但现在我正在尝试检索用户的用户名和性别并显示在我的活动中.

我试图解决这个问题,但尚未找到令人信服的结果.

任何人都可以帮助我摆脱我的要求吗？

注意：我也看到了Facebook开发者页面的文档

这是我用来检索用户数据并在另一个活动中显示的代码.面临的问题是在Facebook的响应被削弱之前加载布局.我怀疑这是因为使用了mAsyncRunner,因为它自己进行控制.我想要找到的是在加载布局之前解析它.

   }}

有人可以帮帮我吗？

解决方法 最后我能够自己解决我的问题.

private static final String[] PERMS = new String[] { "publish_stream" };----->this.facebookConnector = new FacebookConnect(APP_ID,PERMS);---->JsONObject Json = Util.parseJson(response);fbGender = Json.getString("gender");fbname = Json.getString("name");

这是我的代码如何提取数据
