Windows phone 8 在wp8中，应用程序在前台运行时如何获取Toast通知
我想在我的windows phone应用程序中实现“toast”通知。我正在实现推送消息，但我希望它们始终显示。无论应用程序是否正在运行。推送通知将在应用程序关闭时处理它，但不会在应用程序运行时处理。如果我手动创建一个shelltoast，它也不会显示。更难的是，我不能使用任何外部dll。我只想使用代码。最好的方法是什么？我已经知道ToastNotificationReceived事件。我想知道如何实现它，这样它就可以在不使用框架的情况下显示类似于“toast”的消息 我的代码在下面 PushPlugin.cs（c#代码） 在javascript中Windows phone 8 在wp8中，应用程序在前台运行时如何获取Toast通知,windows-phone-8,phonegap-pushplugin,Windows Phone 8,Phonegap Pushplugin,我想在我的windows phone应用程序中实现“toast”通知。我正在实现推送消息，但我希望它们始终显示。无论应用程序是否正在运行。推送通知将在应用程序关闭时处理它，但不会在应用程序运行时处理。如果我手动创建一个shelltoast，它也不会显示。更难的是，我不能使用任何外部dll。我只想使用代码。最好的方法是什么？我已经知道ToastNotificationReceived事件。我想知道如何实现它，这样它就可以在不使用框架的情况下显示类似于“toast”的消息 我的代码在下面 PushP

在没有Windows Phone 8 Update 3的设备上，当目标应用程序在前台运行时，不会显示toast通知。在使用Windows Phone 8 Update 3的设备上，当目标应用程序在前台运行时，会显示toast通知，但会被其他活动（如电话或锁定屏幕）遮挡 下面的C代码示例显示了用于使用本地代码创建toast通知的属性
// Create a toast notification.
// The toast notification will not be shown if the foreground app is running.
ShellToast toast = new ShellToast();
toast.Title = "[title]";
toast.Content = "[content]";
toast.Show();
这就是您在没有Windows Phone 8 Update 3的设备上查找的所有内容，当目标应用程序在前台运行时，不会显示toast通知。在使用Windows Phone 8 Update 3的设备上，当目标应用程序在前台运行时，会显示toast通知，但会被其他活动（如电话或锁定屏幕）遮挡
