android - 如何在android中将数字显示为通知而不是图像？

Question

我是 android 新手，我正在尝试在通知栏中显示通知。我已经在通知栏中显示了图像图标，但我想在 facebook 通知中显示数字通知。

Intent intent = new Intent(this, NotificationReceiverActivity.class);
    PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);
    // Build notification
    // Actions are just fake
    Notification noti = new NotificationCompat.Builder(this)
    .setContentTitle("New mail from " + "test@gmail.com")
    .setContentText("Subject")
    .setSmallIcon(R.drawable.icon)
    .setContentIntent(pIntent)
    .setNumber(4)    
    .addAction(R.drawable.icon, "Call", pIntent)
    .addAction(R.drawable.icon, "More", pIntent)
    .addAction(R.drawable.icon, "And more", pIntent).build();







    // Because the ID remains unchanged, the existing notification is     
    // updated.     



    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    // Hide the notification after its selected
    noti.flags |= Notification.FLAG_AUTO_CANCEL;

    notificationManager.notify(0, noti);
