你必须像这样使用这种方式时，用户按下注销按钮，你必须执行此代码

public void runTestLogout() { 
    if (testLogout()) { 
     logoutText.setText("Logout Tests Passed"); 
    } else { 
     logoutText.setText("Logout Tests Failed"); 
    } 
} 



public boolean testLogout() { 
    try { 
     Log.d("Tests", "Testing logout"); 
     String response = authenticatedFacebook.logout(this); 
     Log.d("Tests", "Got logout response: *" + response + "*"); 
     if (!response.equals("true")) { 
      return false; 
     } 

     Log.d("Tests", "Testing logout on logged out facebook session"); 
     try { 
      Util.parseJson(authenticatedFacebook.logout(this)); 
      return false; 
     } catch (FacebookError e) { 
      if (e.getErrorCode() != 101 || 
        !e.getMessage().equals("Invalid API key")) { 
       return false; 
      } 
     } 

     Log.d("Tests", "Testing logout on unauthenticated object"); 
     try { 
      Util.parseJson(new Facebook(APP_ID).logout(this)); 
      return false; 
     } catch (FacebookError e) { 
      if (e.getErrorCode() != 101 || 
        !e.getMessage().equals("Invalid API key")) { 
       return false; 
      } 
     } 

     Log.d("Tests", "All Logout Tests Passed"); 
     return true; 
    } catch (Throwable e) { 
     e.printStackTrace(); 
     return false; 
    } 
} 

最主要的是

String response = authenticatedFacebook.logout(this); 

运行这段代码，你会被注销，现在你可以再次登录，您将得到空的用户名和密码按钮
