Android 振动不适用于带有自定义声音的通知

以下方法通过自定义声音和频道显示通知。问题是振动不起作用。我试过研究和尝试，但没有成功

private void showNotification(){
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

        Uri soundUri = Uri.parse("android.resource://" + getApplicationContext().getPackageName() + "/" + R.raw.messenger);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, ChannelId)
                .setSmallIcon(R.drawable.ic_stat_facebookmessengernotificationicon)
                .setContentTitle("John Doe")
                .setContentText("Hey, What's Up!")
                .setAutoCancel(true)
                .setSound(soundUri)
                .setContentIntent(pendingIntent);

        NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            if(soundUri != null){
                notificationBuilder.setDefaults(Notification.DEFAULT_VIBRATE);
                AudioAttributes audioAttributes = new AudioAttributes.Builder()
                        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                        .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                        .setLegacyStreamType(AudioManager.STREAM_NOTIFICATION)
                        .build();
                NotificationChannel notificationChannel = new NotificationChannel(ChannelId,"Messenger",NotificationManager.IMPORTANCE_DEFAULT);
                notificationChannel.setSound(soundUri,audioAttributes);
                notificationChannel.enableVibration(true);
                notificationChannel.setVibrationPattern(new long[]{ 100 });
                mNotificationManager.createNotificationChannel(notificationChannel);
            }
        }
        mNotificationManager.notify(0, notificationBuilder.build());
    }

这与定制声音无关。你真的没有设定任何模式。振动模式中的第一个值定义打开可控震源之前等待的毫秒数。下一个值指示在关闭可控震源之前保持可控震源打开的毫秒数，后续值在这两个值之间交替。所以事实上，模式序列意味着关闭，打开，关闭，打开…，所以要有任何振动，至少需要两个值。我想你很可能是这个意思：

notificationChannel.setVibrationPattern(new long[]{ 0, 100 });

另外，调用notificationChannel.enablesvibration（true）是多余的，因为设置有效模式会自动启用它（请参阅）
