1、簡易計算器,默認(rèn)執(zhí)行1+1的計算,點擊go按鈕執(zhí)行計算,先看效果圖,如下首先建立一個ICallback.aidl文件,作為Activity中的回調(diào)方法Java代碼//MyAIDLfile,namedSomeClass.aidlpackagecom.zhang.test.service;//Seethelistaboveforwhichclassesneed//importstatements(hint--mostofthem)//Declaretheinterface.interfaceICallback{//Meth

4、e回調(diào),以及在Service中onBind時返回的Binder注意:aidl中import不能寫com.xxx.*,要寫全類的路徑Java代碼packagecom.zhang.test.service;importcom.zhang.test.service.ICallback;interfaceIService{voidregisterCallback(ICallbackcb);voidunregisterCallback(ICallbackcb);}復(fù)制代碼接下來是service,CalculateService.
