<打击>你不能，对不起更新：现在可以与Android 4.3+ <一href="http://developer.android.com/reference/android/service/notification/NotificationListenerService.html#getActiveNotifications%28%29">http://developer.android.com/reference/android/service/notification/NotificationListenerService.html#getActiveNotifications()

不过，你总是可以简单地取消（）它 - 取消通知不在屏幕上是完全正常的。相反，你可以随时安全地调用通知（）再次对同一通知，它也不会引起问题如果通知已经在屏幕上。

I have made an app that sets notifications in the drop-down status bar of Android phones. However, there is a bug in my code (sometimes the notifications are set, sometimes they are not). I want to be able TO CHECK (in the code) IF THE NOTIFICATION IS VISIBLE TO THE USER. (i.e. can the user see the notification in the status bar?).

How can I do this? (Thanks in advance).

Sample code is greatly appreciated.

You can't, sorry. Update: Now possible with Android 4.3+ http://developer.android.com/reference/android/service/notification/NotificationListenerService.html#getActiveNotifications()

However, you can always simply cancel() it -- canceling a Notification that is not on-screen is perfectly fine. Conversely, you can always safely call notify() again for the same Notification, and it too will not cause a problem if the Notification is already on-screen.
