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();
	}

}
