如何更新通知 [英] How to update Notification

问题描述

我的Android应用程序中有一个Notification.这个Notification有一个进度条.

I have a Notification in my android application. And this Notification has a progress bar.

我的问题是:如果我在Notification的进度栏中更新进度，我应该传递Notification的SAME实例还是创建Notification的新实例?

My question is: if I update progress in the progress bar of my Notification, should I pass the SAME instance of Notification or create a new instance of Notification?

我应该这样做:

mNotification = new Notification(..); // create in the constructor of my activity

getNotificationManager().notify(TAG, FILE_UPLOAD_ID, mNotification);

或

getNotificationManager().notify(TAG, FILE_UPLOAD_ID, new Notification(...) );
