引脚通知到通知区域的顶部 [英] Pin Notification to top of notification area

问题描述

我有被刷新，每三秒钟的通知（即发送）。我给自己定了FLAG_ONGOING_EVENT标志和FLAG_NO_CLEAR标志，以便始终显示。的问题是，如果例如下载是活动的（它显示在通知区域中的进度条），这两个通知，不断变换位置，因为它们都是每隔几秒钟刷新。

我怎么能销我的通知列表的顶部（或一些静态的位置），使之停止我每次调用更新时间 NotificationManager.notify（）？

编辑：这里的code更新通知。它的运行每隔三秒钟。

 的通知的通知=新的通知（）;
notification.contentView = appBarNotification; //这个设置改变的通知内容
notification.flags | = Notification.FLAG_ONGOING_EVENT;
notification.flags | = Notification.FLAG_NO_CLEAR;

意图notificationIntent =新意图（）;
PendingIntent contentIntent = PendingIntent.getActivity（此，0，notificationIntent，0）;
notification.contentIntent = contentIntent;
notification.icon = R.drawable.icon;

nm.notify（APP_BAR_NOTIFICATION，通知）;
 

解决方案

有一个解决方案，它正是你想要的。

在通知类，有一个公共领域的名为< A HREF =htt​​p://developer.android.com/reference/android/app/Notification.html#when相对=nofollow>当。根据API：

  

的时间戳通知。图标和扩展视图通过此键进行排序。

默认的行为（code和codeRS一样:)是给的在的通知的时间戳记：

  notification.when = System.currentTimeMillis的（）;
 

所以 - 为了保持通知的正确顺序，所有你需要做的就是给它一个preset的时间戳来代替：

  notification.when = previousTimestamp;
 

当你这样做你所有的通知，他们认为他们的订单。我有同样的问题，因为你并解决了这种方式。

I have a Notification which is refreshed (i.e. sent) every three seconds. I've set the FLAG_ONGOING_EVENT flag and the FLAG_NO_CLEAR flag so that is always shown. The problem is, that if e.g. a download is active (which displays a progress bar in the notification area) both notifications constantly switch positions as they are both refreshed every few seconds.

How can I pin my notification to the top of the list (or to some static position), so that it stops jumping around every time I update it by calling NotificationManager.notify()?

Edit: Here's the code to update the notification. It's run every three seconds.

Notification notification = new Notification();
notification.contentView = appBarNotification; // this sets the changed notification content
notification.flags |= Notification.FLAG_ONGOING_EVENT;  
notification.flags |= Notification.FLAG_NO_CLEAR; 

Intent notificationIntent = new Intent();
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.contentIntent = contentIntent;
notification.icon = R.drawable.icon;

nm.notify(APP_BAR_NOTIFICATION, notification);

解决方案

There is a solution that does exactly what you want.

In the Notification class, there is a public field called when. According to the API:

The timestamp for the notification. The icons and expanded views are sorted by this key.

The default behaviour (for code and coders alike :) is to give when the timestamp of the notification:

notification.when = System.currentTimeMillis();

So - in order to maintain the correct order of notifications, all you need to do is give it a preset timestamp instead:

notification.when = previousTimestamp;

When you do this with all of your notifications, they maintain their order. I had the same problem as you and solved it this way.
