这就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，我可以显示另一个 Activity 。
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 Activity 中。
我正在尝试解决这个问题，但还没有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 Activity 中显示的代码。我面临的问题是布局是在 facebook 的响应被删除之前加载的。我怀疑这是因为使用了 mAsyncRunner，因为它自行控制。我想知道的是如何在加载布局之前解析它。
public class FaceBookRetrieval extends Activity{
this.facebookConnector = new FacebookConnect(APP_ID, this,
getApplicationContext(), PERMS);
}
public class FacebookConnect {
public FacebookConnect fb = null;
private Facebook facebook = null;
private Context context;
private String[] permissions;
public static final String TAG = "FACEBOOK";
private AsyncFacebookRunner mAsyncRunner;
private SharedPreferences sharedPrefs;
private ProgressBar pb;
public String fbName, fbGender;
private Activity activity;
public String check = "false";
private SessionListener mSessionListener = new SessionListener();;
public FacebookConnect(String appId, Activity activity, Context context,
String[] permissions) {
this.facebook = new Facebook(appId);
mAsyncRunner = new AsyncFacebookRunner(facebook);
SessionStore.restore(facebook, context);
SessionEvents.addAuthListener(mSessionListener);
SessionEvents.addLogoutListener(mSessionListener);
this.context = context;
this.permissions = permissions;
this.activity = activity;
}
public void login() {
if (!facebook.isSessionValid()) {
facebook.authorize(this.activity, this.permissions,
new LoginDialogListener());
}
}
public void getID() {
login();
return;
}
public boolean isSession() {
sharedPrefs = PreferenceManager.getDefaultSharedPreferences(context);
String access_token = sharedPrefs.getString("access_token", "x");
Long expires = sharedPrefs.getLong("access_expires", -1);
Log.d(TAG, access_token);
facebook.setAccessToken(null);
facebook.setAccessExpires(-1);
if (access_token != null && expires != -1) {
// facebook.setAccessToken(access_token);

}
return facebook.isSessionValid();
}

public Facebook getFacebook() {

}
谁能帮帮我？
最佳答案
终于可以自己解决问题了。
private static final String[] PERMS = new String[] { "publish_stream" };
----->
this.facebookConnector = new FacebookConnect(APP_ID, this, getApplicationContext(), PERMS);
---->
JSONObject json = Util.parseJson(response);
fbGender = json.getString("gender");
fbName = json.getString("name");
这是我提取数据的一段代码
