摘要通知触发音效

Question

出于测试目的，我将发送2条通知，并将其与摘要通知捆绑在一起。 它可以工作，但是会引起3种声音效果，这意味着有3个单独的通知到达。这是预期的行为吗？

public void sendOnChannel1(View v) {
    String title1 = "Title 1";
    String title2 = "Title 2";
    String message1 = "Message 1";
    String message2 = "Message 2";

    Notification notification1 = new NotificationCompat.Builder(this, CHANNEL_1_ID)
            .setSmallIcon(R.drawable.ic_one)
            .setContentTitle(title1)
            .setContentText(message1)
            .setGroup("example_group")
            .build();

    Notification notification2 = new NotificationCompat.Builder(this, CHANNEL_1_ID)
            .setSmallIcon(R.drawable.ic_one)
            .setContentTitle(title2)
            .setContentText(message2)
            .setGroup("example_group")
            .build();

    Notification summaryNotification = new NotificationCompat.Builder(this, CHANNEL_1_ID)
            .setSmallIcon(R.drawable.ic_one)
            .setContentTitle("summary content title")
            .setContentText("summary content text")
            .setStyle(new NotificationCompat.InboxStyle()
                    .addLine(title2 + "  " + message2)
                    .addLine(title1 + "  " + message1)
                    .setBigContentTitle("2 new messages")
                    .setSummaryText("user@example.com"))
            .setGroup("example_group")
            .setGroupSummary(true)
            .build();

    notificationManager.notify(1, notification1);
    notificationManager.notify(2, notification2);
    notificationManager.notify(3, summaryNotification);
}

我知道了。 为避免摘要引起混乱，我们必须在其上调用.setGroupAlertBehavior(NotificationCompat.GROUP_ALERT_CHILDREN)。
