为什么我登录了之后我的Facebook会话是否仍然有效？ [英] Why is my facebook session still valid after I am logged out?

问题描述

我注销code：

if(fb.isSessionValid()){    
            masyncfb.logout(this, new RequestListener() {
                  @Override
                  public void onComplete(String response, Object state) {
                      Log.d(TAG, "Logging you out: "+response);
                  }

                  @Override
                  public void onIOException(IOException e, Object state) {}

                  @Override
                  public void onFileNotFoundException(FileNotFoundException e,
                        Object state) {}

                  @Override
                  public void onMalformedURLException(MalformedURLException e,
                        Object state) {}

                  @Override
                  public void onFacebookError(FacebookError e, Object state) {}
                });
                      updateButtonImage();                  

        }else{

和我的 updateButtonImage（）方法是：

private void updateButtonImage() {
        // TODO Auto-generated method stub
        if(fb.isSessionValid()){
            Toast.makeText(MainActivity.this, "logged in", Toast.LENGTH_LONG).show();
            button.setImageResource(R.drawable.logout);
        }else{
            button.setImageResource(R.drawable.login);
            Toast.makeText(MainActivity.this, "logged out", Toast.LENGTH_LONG).show();
        }
    }

updateButtonImage（）方法从登录到注销按钮图像登录后的变化，但不会改变从'注销'到'按钮注销后登录。我相信，我已经成功地从Facebook注销点击注销按钮（来自logcat中）之后。因此，这意味着我的会议仍然是有效的，虽然我已经成功地从Facebook注销。 为什么？如何解决这个问题呢？所有我需要从注销按钮更改为登录。 我应该怎么办？

updateButtonImage() method changes the button image from 'Log In' to 'Log Out' after login but doesn't change the button from 'Log Out' to 'Log In' after logout. I am sure that I have successfully logged out from Facebook after clicking the logout button(from logcat). so, that means my session is still valid, although I have successfully logged out from facebook. why? how can i fix the problem? all i need to change button from 'Log Out' to 'Log In'. what should i do?

N.B：我使用Facebook的SDK

编辑

我觉得我试图注销方法的线程之前改变我的按钮AsyncFacebookRunner.java完成其工作。如果这是真的话，我应该如何等待线程完成工作，然后执行我的 updateButtonImage（）方法。

i think i am trying to change my button before the thread in logout method in AsyncFacebookRunner.java finished its job. if it is true then, how should i wait for the thread to complete its work and then execute my updateButtonImage() method.

推荐答案

要摆脱它，我用 sessionlogin 。就这样，这是工作的罚款。

To get rid of it, I use sessionlogin. With that, it is working fine.
