IPerson.aidl

package com.zzl.test;interface IPerson { void setName(String name);void setAge(int age);String display();}

IPersonImpl

package com.zzl.test;import android.os.RemoteException;public class IPersonImpl extends IPerson.Stub{private String name;private int age;@Overridepublic String display() throws RemoteException {return "name="+name+"age="+age;}@Overridepublic void setAge(int age) throws RemoteException {this.age = age;}@Overridepublic void setName(String name) throws RemoteException {this.name = name;}}

MyRemoteService

package com.zzl.test;import com.zzl.test.IPerson.Stub;import android.app.Service;import android.content.Intent;import android.os.IBinder;public class MyRemoteService extends Service{private Stub iPerson = new IPersonImpl();@Overridepublic IBinder onBind(Intent intent) {// TODO Auto-generated method stubreturn iPerson;}}

MainActivity

注意：gen 下的 com.zzl.test下的文件时自动生成的。

这里的src下的com.zzl.test这个包是从服务器拷过来的。
MainActivity:

package com.zzl.client;import com.zzl.test.IPerson;import android.app.Activity;import android.app.Service;import android.content.ComponentName;import android.content.Intent;import android.content.ServiceConnection;import android.os.Bundle;import android.os.IBinder;import android.os.RemoteException;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.Toast;public class MainActivity extends Activity {private IPerson iPerson;    private Button btn_start;    private ServiceConnection conn = new ServiceConnection(){@Overridesynchronized public void onServiceConnected(ComponentName name, IBinder service) {iPerson = IPerson.Stub.asInterface(service);if(iPerson!=null){try {//RPC方法调用iPerson.setName("无敌小鸡鸡");iPerson.setAge(6);String msg = iPerson.display();Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_LONG).show();} catch (RemoteException e) {e.printStackTrace();}}}@Overridepublic void onServiceDisconnected(ComponentName name) {// TODO Auto-generated method stub}};    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                btn_start = (Button) findViewById(R.id.button1);                btn_start.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {Intent intent = new Intent();//设置Intent 的Action属性intent.setAction("com.zzl.test.MyRemoteService");//绑定服务bindService(intent, conn, Service.BIND_AUTO_CREATE);}});    }}
