Check if my application's notification is running
提问by kkudi
Is there a way I can check programatically whether my app's notification is currently running(shown)?
有没有办法以编程方式检查我的应用程序的通知当前是否正在运行（显示）？
That is to say that NotificationManager.notify()was invoked.
也就是说NotificationManager.notify()被调用了。

No.
不。
That is to say that NotificationManager.notify() was invoked.
也就是说 NotificationManager.notify() 被调用了。
You called notify(). Hence, you already know if notify()was called. You also know if your code calls cancel()or cancelAll(). You will also know, via the various PendingIntentsand flags, if the Notificationgoes away based upon user action. Hence, you have all of the information yourself to determine if the Notificationis on-screen or not.
你打电话给notify()。因此，您已经知道是否notify()被调用。您还知道您的代码是否调用cancel()或cancelAll(). 您还将通过各种PendingIntents和 标志知道是否Notification根据用户操作消失。因此，您自己拥有所有信息来确定Notification屏幕上是否显示。
However, savvy developers will write their apps such that they do not care if their Notificationis on-screen or not.
然而，精明的开发人员会编写他们的应用程序，以便他们不关心他们Notification是否在屏幕上。

Yes. Have a look on this: How to know when my notification is cleared via Clear button?
是的。看看这个：如何知道我的通知何时通过清除按钮被清除？

It seems like you are looking for the deleteIntentfield of the Notificationclass.

You can in API 23 and above. Just call NotificationManager.getActiveNotifications().
您可以在 API 23 及更高版本中使用。就打电话吧NotificationManager.getActiveNotifications()。
