Android訂票系統訂票功能實現(特效點擊按鈕實現票數自動加減1)

要實現的效果是點擊加按鈕就購買分數自動加一，同時計算合計的總計

 

 

先共享一份colors.xml的數據，比較全面，可以根據需要添加

自定義的drawable

 

text_angle_gray.xml

 

 

text_angle.xml，是實現圓角效果的

 

text_angle_right.xml

 

 

 

然後，實現這個ui

	*
	*簡介
	AsyncTask可以使得使用UI線程變的更容易更適當，它可以在後台運行一些操作然後在UI上展現，不用操作具體的線程和handlers
	一個 asynchronous task包括三種基本類型（調用參數，進度和結果），和四個步驟（調用開始，在後台運行，處理進度，結束）
	), and most often will override a second one (onPostExecute(Result).)

	使用方法描述
	Asynchronous Task必須是作為一個子類來使用，
	task實例必須在UI線程創建
	execute(Params...)必須在UI線程調用
	不要手工調用onPreExecute(), onPostExecute(Result), doInBackground(Params...), onProgressUpdate(Progress...)。
	task只可以execute一次，執行多次就報異常
