介紹

客製化 AsyncTask, 專門用來Download Json 並可自行定義初步的解析規則 方便developer使用

Variable

####Required

  1. urlStr : 網址
  2. onFinishListener : Task 結束時所呼叫的interface

####Optional

  1. connectionTimeout : connection timeout 的時間(毫秒)
  2. socketTimeout : socket timeout 的時間(毫秒)
  3. onParseJsonListener : 當原始JSON Object下載完成, 可以定義初步的解析規則

Interface

####OnFinishLoadJsonListener ######有三個method :

  onFinish(JSONObject resultJsonObj)
  onFinish(JSONArray resultJsonAry)
  onFinish(String resultStr)

如果沒有設定 onParseJsonListener, 則會呼叫onFinish(JSONObject resultJsonObj), resultJsonObj 則會是從server上收到的完整 JSONObject

####OnParseJsonListener ######有一個method : onParse(JSONObject jsonObj)

  • 引數 jsonObj 是從server上收到的完整 JSONObject, 使用者可以在 onParse 裡定義自己的parsing規則
  • 回傳值可以為三種:JSONObject, JSONArray, String, 會分別呼叫對應的 onFinish Method
  • 非此三種的回傳值, 則不會呼叫任何一個 onFinish

簡易使用流程

  1. 宣告LoadJsonTask物件
  2. 設定 url 網址
  3. 設定 onFinishLoadJsonListener
  4. 呼叫 loadJsonTaskObject.execute()

--

	LoadJsonTask task = new LoadJsonTask();
	task.setUrlStr(" your url address ");
	task.setOnFinishLoadJsonListener(new OnFinishLoadJsonListener(){
		@override
		public onFinish(JSONObject resultJsonObj){
			//	do you jobs
		}
	});
	task.execute();
