Stacked Wear通知也显示在手机上

Question

我有1个摘要通知和多个堆叠通知。 由于某种原因，堆叠的通知不仅显示在 Andrid Wear设备也在手机上。 根据文件 Stacking Notifications 它们只应显示在手表上。 原因是，NotificationBuilder.setGroup设置为相同的值，只有摘要具有.setSummary（true）。

将 NotificationManager 替换为 NotificationManagerCompat

使用 NotificationManager

private void send() {
    Notification notification1 =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("News1")
                    .setGroup("News")
                    .setContentText("Text")
                    .build();

    Notification notification2 =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("News2")
                    .setGroup("News")
                    .setContentText("Text2")
                    .build();

    NotificationManager notificationManager = (NotificationManager)
            getSystemService(NOTIFICATION_SERVICE);

    notificationManager.notify(1 , notification1);
    notificationManager.notify(2 , notification2);

    Notification Summary = new NotificationCompat.Builder(this)
            .setContentTitle("2 new News")
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentText("Text2")
            .setGroup("News")
            .setGroupSummary(true)
            .build();

    notificationManager.notify(-1 , Summary);
}

使用 NotificationManagerCompat

private void send() {
    Notification notification1 =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("News1")
                    .setGroup("News")
                    .setContentText("Text")
                    .build();

    Notification notification2 =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("News2")
                    .setGroup("News")
                    .setContentText("Text2")
                    .build();

    NotificationManagerCompat notificationManager =
            NotificationManagerCompat.from(this);

    notificationManager.notify(1 , notification1);
    notificationManager.notify(2 , notification2);

    Notification Summary = new NotificationCompat.Builder(this)
            .setContentTitle("2 new News")
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentText("Text2")
            .setGroup("News")
            .setGroupSummary(true)
            .build();

    notificationManager.notify(-1 , Summary);
}
