Android 上监听通知
关于android编程的通知，我有一些疑问。我已经阅读了 notificationmanager、notification 和 notificationbuilder，但它似乎不允许它监听通知。
我想做的是，当任何应用程序发送通知时，我将能够知道它的内容。这实际上可能吗？如何才能做到？
I have some queries when it comes to notification on android programming. I have read up on the notificationmanager, notification and notificationbuilder but it doesn't seem to allow it to listen for notifications.
What I am trying to do is when a notification is send by any application, I will be able to know the contents of it. Is that actually possible and how can it be done?

随着 API 级别 18 的发布，现在有了一个NotificationListenerService。 http://developer.android.com/reference/android/service/notification /NotificationListenerService.html

目前没有通用的方法来拦截从其他应用程序发送的通知。
There is currently no generic way to intercept Notifications sent from other applications.
