1.展示顯示textTicker和只有icon的兩種情況：當參數showTicker為true時顯示否則不顯示

        // In this sample, we‘ll use the same text for the ticker and the expanded notification        CharSequence text = getText(textId);        // choose the ticker text        String tickerText = showTicker ? getString(textId) : null;        // Set the icon, scrolling text and timestamp        Notification notification = new Notification(moodId, tickerText,                System.currentTimeMillis());        // Set the info for the views that show in the notification panel.        notification.setLatestEventInfo(this, getText(R.string.status_bar_notifications_mood_title),                       text, makeMoodIntent(moodId));        // Send the notification.        // We use a layout id because it is a unique number.  We use it later to cancel.        mNotificationManager.notify(R.layout.status_bar_notifications, notification);    

2.展示通過iew建立notifaction

   // Instead of the normal constructor, we‘re going to use the one with no args and fill        // in all of the data ourselves.  The normal one uses the default layout for notifications.        // You probably want that in most cases, but if you want to do something custom, you        // can set the contentView field to your own RemoteViews object.        Notification notif = new Notification();        // This is who should be launched if the user selects our notification.        notif.contentIntent  = PendingIntent.getActivity(this, 0,                new Intent(this, NotificationDisplay.class)        .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)        .putExtra("moodimg", moodId),PendingIntent.FLAG_UPDATE_CURRENT);        // In this sample, we‘ll use the same text for the ticker and the expanded notification        CharSequence text = getText(textId);        notif.tickerText = text;
