When you try to startActivityForResult for Activity that has launchMode="singleTask"; it will not return any values with onActivityResult,and when you set launchMode="standard"; everything works fine, but the system requirements says this Activity must be singleTask, is there anyway to solve this?

推荐答案

的<一个该文档href="http://developer.android.com/reference/android/app/Activity.html#startActivityForResult%28android.content.Intent,%20int%29"><$c$c>startActivityForResult说：

For example, if the activity you are launching uses the singleTask launch mode,
it will not run in your task and thus you will immediately receive a cancel result.

这似乎是没有办法来解决这个问题。

It seems there is no way to get around this.

如果你是被称为活动的开发者，那么你可以把它发送一个广播，当一些结果可用。然后调用活动可以列出这个节目。

If you are the developer of called Activity, then you can have it send a broadcast when some result is available. The calling Activity can then list to this broadcasts.
