24 服务AIDL

AIDL远程访问服务的方法

创建一个接口类写上方法 然后修改后缀java为aidl

在服务中创建一个类继承Stub类

在远程访问服务的进程把AIDL文件复制(包名不能改变)

XXXX.Stub.asInterface(service);即可

服务端结构

MainActivity.java

无实际代码

MyService.java

package com.qf.day24_aidl_server;

import com.qf.day24_aidl_server.MyInterface.Stub;

import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;

public class MyService extends Service{

@Override
public IBinder onBind(Intent intent) {
return new MyBinder();
}
//Stub extends android.os.Binder implements com.qf.day24_aidl_server.MyInterface
public class MyBinder extends Stub{

@Override
public String getServiceData() {
return name();
}

}

//服务里的方法
public String name(){
return "田师傅红烧肉";
}

@Override
public void onCreate() {
super.onCreate();
}

@Override
public boolean onUnbind(Intent intent) {
return super.onUnbind(intent);
}

@Override
public void onDestroy() {
super.onDestroy();
}

}

MyInterface.aidl

package com.qf.day24_aidl_server;

interface MyInterface {

String getServiceData();

}
