android - 如何为预定通知设置默认设备警报音？

Question

我想为我的预定通知设置默认设备警报音，因为普通通知声音很难被注意到。

我尝试通过以下方式获取闹钟音:Uri alarmTone = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);

然后简单地设置它:builder.setSound(alarmTone);

我得到的只是振动，没有任何警报音。有什么想法吗？

完整代码:

private Notification getNotification(String content) {
    Uri alarmTone = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(
            this,
            Receiver.NOTIFICATION_CHANNEL_ID
    );
    builder.setContentTitle("Title");
    builder.setSmallIcon(R.drawable.x);
    builder.setPriority(NotificationCompat.PRIORITY_MAX);
    builder.setDefaults(Notification.DEFAULT_VIBRATE | Notification.DEFAULT_LIGHTS);
    builder.setSound(alarmTone);
    builder.setContentText(content);
    builder.setAutoCancel(true);

    return builder.build();
}

尝试下面的代码:

1.builder.setSound(Settings.System.DEFAULT_NOTIFICATION_URI);
2.mBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
