AIDL

在接口文件AIDLFunctions.aidl中，我们定义一个方法 show

interface AidlFunctions{
void show();
}
服务端：
AIDL的使用，需要一个Service配合，所以我们在服务端还要声明一个Service

public class AIDLService extends Service {
//stub就是系统自动产生的
AidlFunctions.Stub binder;

@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
}

@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
binder = new AidlFunctions.Stub() {

@Override
//这里是我们在接口中声明的方法的实现
public void show() throws RemoteException {
// TODO Auto-generated method stub
System.out.println("--------------------收到----------------------");
}
};
return binder;
}
}
在AndroidManifest声明Service

<service android:name="com.example.androidaidl.AIDLService">
<intent-filter>
<action android:name="com.example.androidaidl.AIDLService" />
</intent-filter>
</service>
客户端：

//绑定服务，要用到ServiceConnection
private ServiceConnection serviceConnection;
//自定义的接口，和服务端一样
private AidlFunctions aidlFunctions;

serviceConnection = new ServiceConnection() {

@Override
public void onServiceDisconnected(ComponentName name) {
// TODO Auto-generated method stub
System.out.println("--------------------ServiceDisconnected----------------------");
}

@Override
public void onServiceConnected(ComponentName name, IBinder service) {
// TODO Auto-generated method stub
System.out.println("--------------------ServiceConnected----------------------");
aidlFunctions = AidlFunctions.Stub.asInterface(service);
}
};
Intent intent = new Intent("com.example.androidaidl.AIDLService");
bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);
//调用show方法
try {
aidlFunctions.show();
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
