我需要使用 Facebook 登录，因此我下载了 sdk 并创建了我的方法。

在我获得用户已登录的信息后，我需要将其发送到我的网络服务并回调我的活动。

这是我的代码。onComplete 我试图解释我需要什么：基本上我需要回调我当前的活动。

public class DisplayLoginActivity extends FragmentActivity {



    /** Called when the activity is first created. */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.display_login_activity);

        login();
    }

    public void login(){
        facebook = new Facebook(kAppId);

        facebook.authorize(this, new DialogListener() {

            @Override
            public void onComplete(Bundle values) {
                System.out.println("onComplete");
                        JSONObject me = null;
                        me = new JSONObject(facebook.request("me"));                

                        String id = me.getString("id");     

                        //I want here to call other async request and make it call back to DisplayLoginActivity, for that
                        //reason i created callback with interface so i need to give this of my Activity
                        //If i give this so it's DialogListener this. I tried to do this DisplayLoginActivity.this but it crashes
            }


            @Override
            public void onFacebookError(FacebookError error) {
                error.getMessage();

            }

            @Override
            public void onError(DialogError e) {

            }

            @Override
            public void onCancel() {

            }

        });
    }

}

也许你有一些想法？谢谢。

我不熟悉 Facebook API，但您是否尝试过简单地调用Looper.prepare()在单独线程上运行的函数（在本例中为 onComplete()）？它应该是线程中的第一个函数调用。
