Question

我必须管理通知，为此我需要管理自定义声音。所以你知道我们怎么做到这一点吗？

我已经将声音文件复制到我的原始文件夹，所以任何人都有任何想法如何将其实现到我的项目中。

提前致谢。

Answer 1

首先将资源（res）中的文件夹命名为 raw 并将文件（YOUR_SOUND_FILE.MP3）放入其中，然后使用下面的代码行进行自定义声音

   NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);

    String title = context.getString(R.string.app_name);

    Intent notificationIntent = new Intent(context,
            SlidingMenuActivity.class);
    notificationIntent.putExtra("isInbox", true);
    // set intent so it does not start a new activity
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);
    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

将这些代码行用于自定义声音

 notification.sound =Uri.parse("android.resource://"+context.getPackageName()+"/"+R.raw.FILE_NAME);//Here is FILE_NAME is the name of file that you want to play


    // Vibrate if vibrate is enabled
    notification.defaults |= Notification.DEFAULT_VIBRATE;
    notificationManager.notify(0, notification);

对于Oreo及更高版本，您需要检查 SDK_VERSION 并使用setSound

的NotificationChannel方法

Uri sound = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + context.getPackageName() + "/" + R.raw.FILE_NAME);  //Here is FILE_NAME is the name of file that you want to play

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

            NotificationChannel mChannel = new NotificationChannel("YOUR_CHANNEL_ID",
                "YOUR CHANNEL NAME",
                NotificationManager.IMPORTANCE_DEFAULT)

            AudioAttributes attributes = new AudioAttributes.Builder()
                    .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                    .build();

            NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, 
                    context.getString(R.string.app_name),
                    NotificationManager.IMPORTANCE_HIGH);

            // Configure the notification channel.
            mChannel.setDescription(msg);
            mChannel.enableLights(true);
            mChannel.enableVibration(true);
            mChannel.setSound(sound, attributes); // This is IMPORTANT


            if (mNotificationManager != null)
                mNotificationManager.createNotificationChannel(mChannel);
        }

                Intent i = new Intent(this, MainActivity.class);
                PendingIntent pi = PendingIntent.getActivity(this, 0, i,
                        PendingIntent.FLAG_CANCEL_CURRENT);

                NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                        .setContentTitle("I want food")
                        .setContentText(notificationcontent)
                        .setSmallIcon(R.drawable.ic_launcher)
                        .setContentIntent(pi)
                        .setAutoCancel(true)
                        .setDefaults(Notification.FLAG_ONLY_ALERT_ONCE);
                NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                MediaPlayer mp= MediaPlayer.create(contexto, R.raw.your_sound);
                mp.start();
                manager.notify(73195, builder.build());
