我知道有吨的同样的问题，但仍OnActivityResult不会被调用。

I know there are tons of the same questions, but still OnActivityResult is not being called.

这是我的code

活动答：

        Intent i = new Intent();
        Bundle b = new Bundle();
        b.putString(ActivityB.LINK, ad.getLink());
        i.putExtras(b);
        i.setClass(this, ActivityB.class);
        startActivityForResult(i, 0);

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        /*handling of result...*/
        super.onActivityResult(requestCode, resultCode, data);
    }

活动B：

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.ad_video);
    Bundle b = this.getIntent().getExtras();
    setResult(0);
    link = b.getString(LINK);
    videoView = (VideoView) findViewById(R.id.surface_view);
     videoView.setVideoPath(_link);
     videoView.requestFocus();
     videoView.start();
     videoView.setOnCompletionListener(new OnCompletionListener() {
        public void onCompletion(MediaPlayer mp)
        {
            setResult(0);
            ActivityB.this.finish();
        }
    });
}

无论我做什么， OnActivityResult 永远不会被调用。 基于其他问题

Whatever i do, OnActivityResult is never called. Based on other questions

我把的setResult与值> 0（0,99）

i put the setResult with values > 0 (0,99)

在Android清单没有launchMode（我也试图把 launchMode标准）

in android manifest there is no launchMode (I also tried to put launchMode to standard)

感谢您的帮助

推荐答案

好吧，我知道了， 主要的问题是，我从卡主机内称为activtiy。我从包含标签（扩展TabActivity一）活动名为它和它的工作原理。

Ok i got it, The main issue was that i called the activtiy from within the tab host. I called it from the Activity that contains the tabs (the one that extends TabActivity) and it works.

所以，简单地说，即使我用每个标签作为一项活动，维基，一个应该叫startActivityForResult是扩展TabActivity的主要活动。

So in brief, even though i'm using each tab as an activity, the one that should call the startActivityForResult is the main activity that extends TabActivity.
