android - 如何在android 8.0中设置带有自定义声音的通知？

Question

我尝试设置自定义通知声音，它在 Oreo(8.0) 设备下工作正常，但在 Oreo 设备中它不会触发自定义声音，始终只触发默认声音。谁能帮忙？

 if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            Notification.Builder notificationBuilder =
                    new Notification.Builder(getApplicationContext(), NOTIFICATION_CHANNEL_ID)
                            .setSmallIcon(R.mipmap.ic_launcher)
                            .setContentTitle(title)
                            .setContentText(content)
                            .setAutoCancel(true)
                            //.setPriority(Notification.PRIORITY_MAX) // this is deprecated in API 26 but you can still use for below 26. check below update for 26 API
                            //.setSound(defaultSoundUri)
                            .setContentIntent(pendingIntent);

            NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications", NotificationManager.IMPORTANCE_HIGH);
            // Configure the notification channel.
            AudioAttributes att = new AudioAttributes.Builder()
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .setContentType(AudioAttributes.CONTENT_TYPE_SPEECH)
                    .build();
            notificationChannel.setSound(defaultSoundUri, att);
            notificationChannel.setDescription(content);
            notificationChannel.enableLights(true);
            notificationChannel.setLightColor(Color.RED);
            notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
            notificationChannel.enableVibration(true);
            notificationManager.createNotificationChannel(notificationChannel);
            notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());

        } else {
            NotificationCompat.Builder notificationBuilder =
                    new NotificationCompat.Builder(getApplicationContext())
                            .setSmallIcon(R.mipmap.ic_launcher)
                            .setContentTitle(title)
                            .setContentText(content)
                            .setAutoCancel(true)
                            .setPriority(Notification.PRIORITY_MAX) // this is deprecated in API 26 but you can still use for below 26. check below update for 26 API
                            .setSound(defaultSoundUri)
                            .setContentIntent(pendingIntent);

            notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());

        }

如果您使用的是 Oreo 下的 Android 版本，您只需将 MY_SOUND_NOTIFICATION.mp3 添加到名为 raw 的文件夹中的Resources，然后开始编写您的代码类，但由于您使用的是 Oreo 或更高版本，因此您需要检查您的 SDK_VERSION 以便使用 NotificationChannel

的名为 setSound 的方法

我不会发布任何代码，因为我没有发布代码来更正。如果您发布一些代码，我很乐意为您提供帮助
