如何在状态栏中显示单个通知图标以显示多个通知

Question

我现在正在显示这样的通知:

NotificationCompat.Builder noBuilder = new NotificationCompat.Builder(this)
    .setSound(sound)
    .setSmallIcon(R.drawable.h) 
    .setLargeIcon(largeIcon)
    .setContentTitle(title)
    .setFullScreenIntent(pendingIntent,true)
    .setContentText(message)
    .setStyle(new NotificationCompat.BigTextStyle()
    .bigText(message))
    .setAutoCancel(true)
    .setPriority(Notification.PRIORITY_HIGH)
    .setContentIntent(pendingIntent);

使用setGroup()键显示组通知

final static String GROUP_KEY_EMAILS = "group_key_emails";
// Build the notification, setting the group appropriately
Notification notif = new NotificationCompat.Builder(mContext)
         .setContentTitle("New mail from " + sender1)
         .setContentText(subject1)
         .setSmallIcon(R.drawable.new_mail)
         .setGroup(GROUP_KEY_EMAILS)
         .build();
// Issue the notification
NotificationManagerCompat notificationManager =
        NotificationManagerCompat.from(this);
notificationManager.notify(notificationId1, notif);

设置setGroupSummary()为一组通知设置摘要
