推荐答案

您应该将 ApplicationIdleDecectionMode 设置为 Enabled 并处理 Obscured 和 >Unobscured 根框架事件:

You should set ApplicationIdleDecectionMode to Enabled and handle Obscured and Unobscured events of root frame:

Microsoft.Phone.Shell.PhoneApplicationService.Current.ApplicationIdleDetectionMode = IdleDetectionMode.Enabled;
      var rootFrame = App.Current.RootVisual as PhoneApplicationFrame;
      if(rootFrame != null)
      {
        rootFrame.Obscured += new EventHandler<ObscuredEventArgs>(rootFrame_Obscured);
        rootFrame.Unobscured += new EventHandler(rootFrame_Unobscured);
      }
