【中文标题】Facebook状态回调不适用于片段

【英文标题】：Facebook Status call back not working with fragment

【问题描述】：

我正在尝试在成功登录的片段中使用 SFB 登录回调（fb 显示应用已授权）但回调不起作用。 当我尝试使用 Activity 相同的代码时，它可以工作。如果出现碎片，我是否遗漏了什么？

public void faceBook(View view) 
    if (FacebookDialog.canPresentShareDialog(getApplicationContext(),
            FacebookDialog.ShareDialogFeature.SHARE_DIALOG)) 
        // Publish the post using the Share Dialog - This is working.
        //When FB not installed else part will execute - There I have issue
     else 
        Session session = Session.getActiveSession();
        if(!session.getState().isOpened()) 
//here am setting the status call back as third parameter "this" and implemented Session.status call back in my class which is extended a fragment
//so publishFeedDialog did not get called after login
            Session.openActiveSession(this, true, this); 
         else 
            publishFeedDialog(session);
        
    


@Override
public void call(Session session, SessionState sessionState, Exception e) 
      //A call supposed to come here after user sign to fb, but that is not happening. (fb shows app as authorized) but callback doesn't work. When I am trying same code with Activity it works
    if(session.getState().isOpened()) 
        publishFeedDialog(session);
    

【问题讨论】：

也许添加一些代码，然后我们将能够决定您是否遗漏了什么

【参考方案1】：

我查看了 facebook Session 类，发现有另一个版本的 Session.openActiveSession() 可以从片段中使用

openActiveSession(context, fragment, allowLoginUI, statusCallback);

确保片段是 android.support.v4.app.Fragment
