第二篇 （Aidl回调）

废话不说,兄弟们继续奔主题 ^_^

结构如图：

Icall代码：

package Aidl_Activity_Service_simple_Icall.Jason;



interface Icall {

	 void showdialog(String p_string);

}

Json代码：

package Aidl_Activity_Service_simple_Icall.Jason;

import Aidl_Activity_Service_simple_Icall.Jason.Icall;

interface Json {

     void register(Icall b);

     void unregister(Icall b);

}

myService代码：

package Aidl_Activity_Service_simple_Icall.Jason;



import android.app.Service;

import android.content.Intent;

import android.os.Handler;

import android.os.IBinder;

import android.os.Message;

import android.os.RemoteCallbackList;

import android.os.RemoteException;



public class myService extends Service {



	

	RemoteCallbackList<Icall> rc=new RemoteCallbackList<Icall>();

	

	Handler hd=new Handler()

	{



		@Override

		public void handleMessage(Message msg) {

			// TODO Auto-generated method stub

			//super.handleMessage(msg);

			if(msg.what==123)

			{

				CallBack();

			}

		//	CallBack();

		}

		

	};

	private Json.Stub js=new Json.Stub() {

		

		public void unregister(Icall b) throws RemoteException {

			// TODO Auto-generated method stub

			rc.unregister(b);

		}

		

		public void register(Icall b) throws RemoteException {

			// TODO Auto-generated method stub

		

			Message msg=hd.obtainMessage(123);

			hd.sendMessage(msg);

			rc.register(b);

			

			

		}

	};

	

	@Override

	public IBinder onBind(Intent intent) {

		// TODO Auto-generated method stub

		//return null;

		return js;

	}



	protected void CallBack() {

		// TODO Auto-generated method stub

		 int i=rc.beginBroadcast();

		 while (i > 0) {

		     i--;

		     try {

		         rc.getBroadcastItem(i).showdialog("成功注册");

		     } catch (RemoteException e) {

		         // The RemoteCallbackList will take care of removing

		         // the dead object for us.

		     }

		 }

		 rc.finishBroadcast();

	}



}
