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();

			}
		});

	}
}
