问题描述

到目前为止，我成功地使用了startActivity功能，现在，我需要用startActivityResult，我有一个问题。

So far, I used the startActivity function with success and now that I need to use the startActivityResult, I have a problem.

在使用此功能时，我期望能够推出的活动是正常启动，但它似乎是onActivityResult函数没有被调用。

When using this function, the activity I expect to be launched is launched correctly but it seems like the onActivityResult function is never called.

下面是我的code在FriendPicker活动，劳克的MoodPicker活动：

Here is my code in the FriendPicker activity, to lauch the MoodPicker activity:

Intent intent = new Intent(FriendPicker.this, MoodPicker.class);
startActivityForResult(intent, 2);

和这里是我的code。在MoodPicker活动：

And here is my code in the MoodPicker activity:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent)
{
    super.onActivityResult(requestCode, resultCode, intent);

    Log.i("in OnActivityResult", "Activity Result");

    switch (requestCode)
    {
        case 2:
            Log.i("in OnActivityResult", "Activity Resut 2");

            break;
    }
}

和没有在我的日志文件被写入（当然，我检查了我的日志文件被正常工作，仔细检查了文本视图输出）。

and nothing in my logfile is written (I of course, checked that my log file was working properly and double check with a text view output).

有什么我忘了在manifest文件中声明？

Is there something I forgot to declare in the Manifest file?

在此先感谢。
