Tosted通知操作按钮在锁定屏幕上不工作

Question

我正在UWP建立音乐播放器。当窗口解锁时，toasted通知上的操作按钮正常工作。当我锁定屏幕，点击动作按钮，然后什么都没有发生。应用程序将处于暂停状态，没有中断点被击中。

我如何使我的应用程序运行，即使windows被锁定从应用程序接收事件？

var toastContent = new ToastContent
            {
                Launch= "",
                Visual = new ToastVisual
                {
                    BindingGeneric = new ToastBindingGeneric
                    {
                        Children =
                        {
                            new AdaptiveText
                            {
                                 HintWrap = false,
                            HintMaxLines = 1,
                            HintStyle = AdaptiveTextStyle.Title,
                                Text = "sdfsd"
                            },
                            new AdaptiveText
                            {
                                 HintWrap = false,
                            HintMaxLines = 1,
                            HintStyle = AdaptiveTextStyle.Caption,
                                Text = "text"
                            }
                        },

                        AppLogoOverride = new ToastGenericAppLogo()
                        {
                            Source = optionalLogoPath
                        }
                    }
                },
                Actions = new ToastActionsCustom()
                {
                    Buttons =
                {
                    new ToastButton("previous", new QueryString()
                    {
                        { "action", "previous" }

                    }.ToString() )
                    {
                        ActivationType= ToastActivationType.Foreground,
                        ImageUri = "prev-focus.png",

                    },
                    new ToastButton("Play", new QueryString()
                    {
                        { "action", "play" }

                    }.ToString() )
                    {
                        ActivationType= ToastActivationType.Foreground,
                        ImageUri = "play-focus.png",

                    },
                    new ToastButton("next", new QueryString()
                    {
                        { "action", "next" }

                    }.ToString() )
                    {
                        ActivationType= ToastActivationType.Background,
                        ImageUri = "next-focus.png"
                    },

                },
                }
            };

            var toast = new ToastNotification(toastContent.GetXml())
            {
                Tag = "some tag",
                SuppressPopup = false
            };

            toastNotifier.Show(toast);

最后，我使用protected override async void OnBackgroundActivated(BackgroundActivatedEventArgs)方法使其工作。
