推荐答案

无法访问呼叫信息.

但是，如果您的应用正在运行并且在 Obscured 事件将被触发.然后，您可以使用 Unobscured、NavigatedTo、Loaded 和Activated 事件以确定应用何时再次获得焦点.

However if your app is running and a call comes in the Obscured event will be triggered. You can then use a combination of the Unobscured, NavigatedTo, Loaded & Activated events to determine when the app has the focus again.

这不会为您提供通话时长，而是提供可能是通话的事件(包括收到的短信、闹钟等)与用户完全返回您的应用之间的时间.这可能是一个足够好的近似值，但这取决于您的需求.

This won't give you the length of the call but rather then time between an event that may be a call (including incoming SMS, alarms, etc.) and the user returning fully to your app. This may be a good enough approximation, but it will depend on your needs.
