问题描述
当您尝试 startActivityForResult 为活动，有 launchMode =singleTask;它不会与 onActivityResult 返回任何值，当你设置 launchMode =标准;一切工作正常，但系统的要求说，这活动必须 singleTask ，反正是有解决这个问题？
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<$c$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.
