Android通知图标

Question

Android开发新手。我想知道是否有可能以编程方式绘制图标放入通知栏？如果我们希望图标显示某些类似电池电量的动态文本，该怎么办？

如果有人有代码示例，它会很好。谢谢。

呼叫我们想要通知的功能。

public void notification(String name) { 

      final int id = 2; 
      String ns = Context.NOTIFICATION_SERVICE; 
      NotificationManager notificationManager = (NotificationManager) getSystemService(ns); 
      int icon = R.drawable.fbc; 
      CharSequence tickerText = "facebook"; 
      long when = System.currentTimeMillis(); 

      Notification checkin_notification = new Notification(icon, tickerText, 
        when); 
      Context context = getApplicationContext(); 
      CharSequence contentTitle = "You are name is"+ name; 
      CharSequence contentText = "Do You want to Check-in ?? "; 

       Intent notificationIntent = new Intent(context, LoginTab.class); 
       PendingIntent contentIntent = PendingIntent.getActivity(context, 0, 
         notificationIntent, 0); 
       checkin_notification.setLatestEventInfo(context, contentTitle, 
         contentText, contentIntent); 
       checkin_notification.flags = Notification.FLAG_AUTO_CANCEL; 
       notificationManager.notify(id, checkin_notification); 

     }
