1、简易计算器,默认执行1+1的计算,点击go按钮执行计算,先看效果图,如下首先建立一个ICallback.aidl文件,作为Activity中的回调方法Java代码//MyAIDLfile,namedSomeClass.aidlpackagecom.zhang.test.service;//Seethelistaboveforwhichclassesneed//importstatements(hint--mostofthem)//Declaretheinterface.interfaceICallback{//Meth

4、e回调,以及在Service中onBind时返回的Binder注意:aidl中import不能写com.xxx.*,要写全类的路径Java代码packagecom.zhang.test.service;importcom.zhang.test.service.ICallback;interfaceIService{voidregisterCallback(ICallbackcb);voidunregisterCallback(ICallbackcb);}复制代码接下来是service,CalculateService.
5、javaJava代码packagecom.zhang.test.service;importandroid.app.Service;importandroid.content.BroadcastReceiver;importandroid.content.Context;importandroid.content.Intent;importandroid.content.IntentFilter;importandroid.os.Handler;importandroid.os.IBinder;importandroi
