第一篇 （ Aidl 进程间通信 )

老规矩，不废话，直奔主题 ^_^

 程序1

 结构如图：

Common_operation代码：

package Aidl_application_communication.Jason;



 interface COMMON_OPERATION {



	int Add(int x,int y);

}

myService代码：

package Aidl_application_communication.Jason;



import android.app.Service;

import android.content.Intent;

import android.os.IBinder;

import android.os.RemoteException;

import Aidl_application_communication.Jason.COMMON_OPERATION.Stub;



public class myService extends Service {

  

	private COMMON_OPERATION.Stub cos=new Stub() {

		

		public int Add(int x, int y) throws RemoteException {

			// TODO Auto-generated method stub

			//return 0;

			return x+y;

		}

	};

	@Override

	public IBinder onBind(Intent arg0) {

		// TODO Auto-generated method stub

		//return null;

		return cos;

	}



}

Aidl_application_communication_1Activity代码：

package Aidl_application_communication.Jason;



import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.Toast;



public class Aidl_application_communication_1Activity extends Activity {



	private Button start_btn;



	/** Called when the activity is first created. */

	@Override

	public void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.main);

		start_btn = (Button) this.findViewById(R.id.start_btn);

		start_btn.setOnClickListener(new OnClickListener() {



			public void onClick(View v) {

				// TODO Auto-generated method stub

				Intent it = new Intent(

						Aidl_application_communication_1Activity.this,

						myService.class);				startService(it);



				Toast.makeText(Aidl_application_communication_1Activity.this,

						"启动", Toast.LENGTH_LONG).show();



			}

		});



	}

}
