处理多个通知/堆垛从GCM通知 [英] Handle multiple Notifications / Stacking Notifications from GCM

问题描述

我只是执行GCM和通知在我的Andr​​oid应用程序，从Apache /基于PHP的Web服务器来了。
该通知已经工作了，但我卡在堆叠的通知，如所描述的这里。

I just implemented GCM and notifications in my Android app, coming from an Apache/PHP-based webserver.
The notifications are already working, but I'm stuck at stacking the notifications, as described here.

我有两种类型我的应用程序的通知，采用的数据来自GCM服务未来：

第1类（消息）：

I have two types of notifications in my app, using data coming from the GCM Service:

Type 1 (Messages):

[data] => Array
(
    [t] => 1
    [other data...]
)

2型（新闻）：

[data] => Array
(
    [t] => 2
    [other data...]
)

这些2种完全不同的通知，我想堆二者彼此分离，但我不能得到这个工作。 我想堆叠起来像这样，只要有多个通知：

These 2 types are completely different notifications, and I would like to stack both of them separate from each other, but I can't get this to work. I would like to stack them like this, as soon as there are multiple notifications:

默认视图

Default View

扩展视图

Expanded View

2的通知ID和原子整数
我试图使用2个不同的通知的ID，以使用相同类型的通知获得overidden

2 Notification IDs and Atomic Integer
I tried to use 2 different notification IDs, so that notifications with the same type get overidden.

if (msg.get("t").toString().equals("1")) {
    notificationNumber = messageCounter.incrementAndGet();
} else {
    notificationNumber = newsCounter.incrementAndGet();
}
[...]
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
    .setNumber(notificationNumber);

如果2消息发送的同时，一切工作正常，计数器显示2.但是，如果有两则通知的一个短暂的延迟，计数器切换到1。

If 2 messages are sent at the same time, everything works fine and the counter shows 2. But if there is a short delay between two notifications, the counter switches to 1.

唯一标识的通知
我也尝试过使用与生成的唯一的ID

Unique Notification IDs
I also tried to use unique IDs generated with

Date now = new Date();
Notification_id = now.getTime();

让没有完全没有堆放或压倒一切的。

so that there isn't no stacking or overriding at all.

我怎样才能解决我的问题？我可以访问$ P $的内容pviously发送的通知，让我可以在Gmail中的扩展视图显示每封邮件在一行，怎么样？我怎么能检查哪些/多少通知的当前显示？
长的问题，非常感谢你！

How can I solve my problem? Can I access the content of the previously sent notifications, so that I can show every message in one line, like in the expanded view of Gmail? How can I check which / how many notifications are currently displayed?
Long question, thank you very much!

推荐答案

我终于找到了解决方案，并最终使用原子整数，但在分离式类：

I finally found the solution and ended up using atomic integers, but in a seperated class:

import java.util.concurrent.atomic.AtomicInteger;

public class Global {
    public static AtomicInteger Counter1 = new AtomicInteger();
    public static AtomicInteger Counter2 = new AtomicInteger();
}

要重新申请开通后，计数器，我把这个在我的MainActivity（称为的onCreate（）和 onResume（）：

To reset the counter after the application opening, i put this in my MainActivity (called in onCreate() and onResume():

private void clearNotifications(){        
    NotificationManager mNotificationManager;
    mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.cancelAll();

    Global.Counter1.set(0);
    Global.Counter2.set(0);
}

当我创建通知，我检查计数器：

When I create the notification, I check the counter:

Counter1 = Global.Counter1.incrementAndGet();
ContentText = (Counter1 < 2) ? /* Single notification */ : /* Stacking */;
