通知中的setgroup()不起作用 [英] setgroup() in notification not working

问题描述

我正在尝试创建通知组，这是我的代码:

I'm tring to create notification group, this is my code:

 // Build the notification, setting the group appropriately
 Notification notif = new NotificationCompat.Builder(getApplicationContext())
          .setContentTitle("New mail from " + 1)
          .setContentText("cv")
          .setSmallIcon(R.drawable.rh_logo)
          .setStyle(new NotificationCompat.InboxStyle()
            .addLine("Alex Faaborg   Check this out")
            .addLine("Jeff Chang   Launch Party")
            .setBigContentTitle("2 new messages")
            .setSummaryText("[e-mail]"))
          .setGroup(GROUP_KEY_EMAILS)
          .setGroupSummary(true)
          .build();

 // Issue the notification



 NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
 notificationManager.notify(++NOTIFICATION_ID, notif);

当我运行该应用程序并发送通知消息时，它们不会分组显示. 有人可以向我解释我需要更改的内容吗?

When I run the app, and send notification messages, they do not show in group. Can someone explain me what I need to change?

推荐答案

在创建自定义通知之前，您必须创建一个组通知.就是这样:

You have to create a group notification before creating your custom notification. Just like this:

NotificationCompat.Builder groupBuilder =
            new NotificationCompat.Builder(context)
                    .setContentTitle(title)
                    .setContentText(content)
                    .setGroupSummary(true)
                    .setGroup("GROUP_1")
                    .setStyle(new NotificationCompat.BigTextStyle().bigText(content))
                    .setContentIntent(pendingIntent);

不要忘记 setGroupSummary 为真.

然后创建您的子通知，该通知的 group值与 groupBuilder 的值相同.这里是"GROUP_1".

Then create your child notification which group value is same to groupBuilder's value。Here is "GROUP_1".

NotificationCompat.Builder builder =
            new NotificationCompat.Builder(context)
                    .setSmallIcon(R.drawable.ic_stat_communication_invert_colors_on)
                    .setContentTitle(title)
                    .setContentText(content)
                    .setGroup("GROUP_1")
                    .setStyle(new NotificationCompat.BigTextStyle().bigText(content))
                    .setContentIntent(pendingIntent)

最后使用NoticationManagerCompat通知它们.

Finally use NoticationManagerCompat to notify them.

    NotificationManagerCompat manager = NotificationManagerCompat.from(context);
    manager.notify(GROUP_ID, groupBuilder.build());
    manager.notify(id, builder.build());
