Service这边只要定义一个服务:

interface IDog{
String getName();
int getAge();
}

然后在服务器的Service上创建Stub,Stub是存根的意思，在客户端也有一个一样的IDog类，通信的时候传递的都是IDog类型:

服务端Service的写法:

import com.example.aidlservicedemo.domain.IDog.Stub;

public class BaseTypeService extends Service {
private final String TAG="main";
private DogBinder binder=null;
private String[] names=new String[]{
"小白","旺财","小黑"}
;
private int[] ages=new int[]{
1,2,3}
;
/** * Stub的实现类，Stub内部实现了Binder * 内部实现AIDL定义的方法 */ public class DogBinder extends Stub{
@Override public String getName() throws RemoteException {
return names[0];
}
@Override public int getAge() throws RemoteException {
return ages[1];
}
}
@Override public void onCreate() {
super.onCreate();
// 实例化Binder对象 binder=new DogBinder();
Log.i(TAG, "创建服务成功");
}
@Override public IBinder onBind(Intent intent) {
Log.i(TAG, "绑定服务成功");
// 返回Binder对象 return binder;
}
}

public class BaseTypeActivity extends Activity {
private Button btn_startService, btn_endService,btn_getServiceData;
private IDog dogService;
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_service);
btn_startService = (Button) findViewById(R.id.btn_startService);
btn_endService = (Button) findViewById(R.id.btn_endService);
btn_getServiceData = (Button) findViewById(R.id.btn_getServiceData);
btn_startService.setOnClickListener(click);
btn_endService.setOnClickListener(click);
btn_getServiceData.setOnClickListener(click);
}
private View.OnClickListener click = new OnClickListener() {
@Override public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_startService: startService();
break;
case R.id.btn_endService: endService();
break;
case R.id.btn_getServiceData: getServiceDate();
break;
}
}
}
;
/* * 获取数据 */ private void getServiceDate() {
try {
if(dogService!=null){
StringBuilder sBuilder=new StringBuilder();
sBuilder.append("name:"+dogService.getName());
sBuilder.append("nage:"+dogService.getAge());
//获取数据，这个结果应该是小白，2 Toast.makeText(BaseTypeActivity.this, sBuilder.toString(), Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(BaseTypeActivity.this, "请先绑定服务", Toast.LENGTH_SHORT).show();
}
}
catch (Exception e) {
e.printStackTrace();
}
}
private ServiceConnection connBase=new ServiceConnection() {
@Override public void onServiceDisconnected(ComponentName name) {
dogService=null;
}
@Override public void onServiceConnected(ComponentName name, IBinder service) {
// IDog.Stub.asInterface，获取接口 dogService=IDog.Stub.asInterface(service);
//表示拿到的这个Service对象 }
}
;
/** * 开始服务 */ private void startService(){
Intent intent=new Intent();
intent.setAction("cn.bgxt.Service.BASE_TYPE_SERVICE");
//这个必须跟服务端menufest上的action一致 bindService(intent, connBase, BIND_AUTO_CREATE);
Toast.makeText(BaseTypeActivity.this, "开始绑定服务", Toast.LENGTH_SHORT).show();
}
/** * 停止服务 */ private void endService(){
if(connBase!=null) {
unbindService(connBase);
Toast.makeText(BaseTypeActivity.this, "服务解除绑定", Toast.LENGTH_SHORT).show();
}
}
}

如果AIDL通讯传递是自定义类型:

一个常用的根据user来返回对象message信息的例子，user ,message都是自定义类型:

public class Message implements Parcelable {
private int id;
private String msgText;
private String fromName;
private String date;
}
public class User implements Parcelable {
private int id;
private String username;
private String password;
}

message.aidl:

parcelable Message;

user.aidl

parcelable User;

服务器代码:

public class CustomTypeService extends Service {
private static final String TAG = "main";
private MsgBinder msgBinder = null;
private static Map> map = new HashMap>();
static {
for (int i = 0;
i < 3;
i++) {
User user = new User(i, "jack" + i, "99" + i);
List messages = new ArrayList();
Message msg = null;
if (i == 0) {
msg = new Message(i, "这两天好吗？", "Jerry", new Date().toGMTString());
messages.add(msg);
}
map.put(user, messages);
}
}
public class MsgBinder extends Stub {
@Override public List getMes(User us) throws RemoteException {
for (Map.Entry> msgs : map.entrySet()) {
if (msgs.getKey().getUsername().equals(us.getUsername()) && msgs.getKey().getPassword().equals(us.getPassword())) {
Log.i(TAG, "找到信息了");
return msgs.getValue();
}
}
Log.i(TAG, "没找到信息了");
return map.get(us);
}
}
@Override public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub return msgBinder;
}
@Override public void onCreate() {
// TODO Auto-generated method stub super.onCreate();
msgBinder = new MsgBinder();
}
@Override public void onDestroy() {
msgBinder = null;
super.onDestroy();
}
}

private static User[] users = new User[] {
new User(0, "jack0", "990")}
;
/** * 获取其他线程服务数据 */ private void getServiceDate(){
try {
List msgs=getMsg.getMes(users[0]);
StringBuilder sBuilder=new StringBuilder();
for(Message msg:msgs){
sBuilder.append(msg.toString()+"n");
}
Toast.makeText(CustomTypeActivity.this, sBuilder.toString(), Toast.LENGTH_SHORT).show();
}
catch (Exception e) {
Toast.makeText(CustomTypeActivity.this, "获取数据出错", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
