android NotificationManager:通知欄

/***
 * 顯示指定通知
 * 
 * @param strTitle
 *            通知內容
 * @param notification_id
 *            通知id
 */
public void showNotification(String strText, int notification_id) {
    // 得到NotificationManager
    Log.i("ANYCHAT", "showNotification");
    NotificationManager notificationManager = (NotificationManager) getSystemService(android.content.Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(R.drawable.ic_launcher, strText, System.currentTimeMillis());
    notification.flags |= Notification.FLAG_SHOW_LIGHTS;
    notification.flags |= Notification.FLAG_AUTO_CANCEL;  //通知被點擊後，自動消失
    notification.defaults = Notification.DEFAULT_LIGHTS;
    notification.ledARGB = Color.BLUE;
    notification.ledOnMS = 100;
    notification.ledOffMS = 100;
    Intent notificationIntent = new Intent(BussinessCenter.mContext, BussinessCenter.mContext.getClass());
    notificationIntent.putExtra("action", 2);
    notificationIntent.setAction(Intent.ACTION_MAIN);
    notificationIntent.addCategory(Intent.CATEGORY_LAUNCHER);
    PendingIntent contentIntent = PendingIntent.getActivity(
            BussinessCenter.mContext, 0, notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);
    notification.setLatestEventInfo(this,this.getString(R.string.BACKING_RUNING), strText,contentIntent);
    notificationManager.notify(notification_id, notification);
}

在低版本中的代碼：(來自於AnyChatCallCenter中BcakService類的裏面)，
但是，在版本里面已經被棄用，甚至hide起來了。

低於API Level 11版本，也就是Android 2.3.3以下的系統中，setLatestEventInfo()函數是唯一的實現方法。前面的有關屬性設置這裏就不再提了，網上資料很多。

在高版本中，可以用Builder和build()函數來配套的方便使用notification了。

Notification notification = new Notification.Builder(context)    
     .setAutoCancel(true)    
     .setContentTitle("title")    
     .setContentText("describe")    
     .setContentIntent(pendingIntent)    
     .setSmallIcon(R.drawable.ic_launcher)    
     .setWhen(System.currentTimeMillis())    
     .build();
