将通知声音设置为默认闹钟铃声 [英] Set Notification sound as default alarm ringtone

问题描述

我发现的是，如果我将通知声音设置为设备默认的闹钟铃声，如下所示:

What I've discovered is, that if I set notification sound as devices default alarm ringtone like this:

val alarmTone = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM)
val builder = NotificationCompat.Builder(
        context,
        CHANNEL_ID
)
builder.setDefaults(Notification.DEFAULT_VIBRATE or Notification.DEFAULT_LIGHTS)
builder.priority = NotificationCompat.PRIORITY_DEFAULT
builder.setSound(alarmTone)

这几乎适用于所有较旧的设备版本，但是一旦我在 Android 8.0 设备上对其进行测试，它就会将声音设置为默认通知声音.如何获取设备 8.0 的默认闹钟铃声?

This works on almost all older device versions, but as soon as I test it on Android 8.0 device, it sets sound as default notification sound. How can I get default alarm ringtone for devices 8.0?

推荐答案

Oreo 8.0 之后您可能已经创建了播放通知声音的频道.

After 8.0 Oreo You may have created the channel for play notification sound.

private static void initChannels(NotificationManager notificationManager) {
    if (Build.VERSION.SDK_INT < 26) {
        return;
    }

    NotificationChannel channel = new NotificationChannel("ID",
            "NAME",
            NotificationManager.IMPORTANCE_LOW);
    channel.setDescription("DESC");
    channel.enableVibration(false);
    AudioAttributes audioAttributes = new AudioAttributes.Builder()
            .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
            .setUsage(AudioAttributes.USAGE_NOTIFICATION_RINGTONE)
            .build();
    channel.setSound(Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.notification), audioAttributes);

    notificationManager.createNotificationChannel(channel);
}

确保您使用的是 targetSdkVersion 26 或更高版本

Make sure you are using targetSdkVersion 26 or above
