复习Android之Service的AIDL传值

1. Service的类型
   本片按地点划分种类
   

2. 开启关闭本地服务

public static void bindLocalService(Context context, ServiceConnection serviceConnection) {
        if (context == null || null == serviceConnection) {
            return;
        }
        //通过Intent指定服务端的服务名称和所在包，与远程Service进行绑定
        Intent intent = new Intent();
        intent.setClass(context, LocalService.class);
        Bundle bundle = new Bundle();
        bundle.putString("name", "张三");
        bundle.putString("age", "25");
        intent.putExtras(bundle);
        //绑定服务,传入intent和serviceConnection对象
        context.bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);
 }

/**
     * 解绑服务
     *
     * @param context
     */
    public static void unBindLocalService(Context context, ServiceConnection serviceConnection) {
        if (context == null || null == serviceConnection) {
            return;
        }
        try {
            // 当需要多次调用doSomething()方法的时候，如果直接bindService是会报错的
            context.unbindService(serviceConnection);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

3. 开启关闭远程服务

/**
     * 绑定远程服务
     *
     * @param context
     * @param serviceConnection
     */

    public static void bindTheRemoteService(Context context, ServiceConnection serviceConnection) {
        if (context == null || null == serviceConnection) {
            return;
        }
        //通过Intent指定服务端的服务名称和所在包，与远程Service进行绑定
        Intent intent = new Intent();
        intent.setClass(context, TheRemoteService.class);
        Bundle bundle = new Bundle();
        bundle.putString("Fruitname", "苹果");
        bundle.putString("Fruitage", "今年");
        intent.putExtras(bundle);
        //绑定服务,传入intent和serviceConnection对象
        context.bindService(intent, serviceConnection, Context.BIND_AUTO_CREATE);
    }

/**
     * 解绑远程服务
     *
     * @param context
     * @param serviceConnection
     */
    public static void unBindTheRemoteService(Context context, ServiceConnection serviceConnection) {
        if (context == null || null == serviceConnection) {
            return;
        }

            // 当需要多次调用doSomething()方法的时候，如果直接bindService是会报错的
            context.unbindService(serviceConnection);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

想要开启service还需要在manifest注册，这样你就可以开启service了。

  <!--本地 service-->
        <service android:name=".service.LocalService">
            <intent-filter>
                <action android:name=" com.aidl.myapplication.service.LocalService" />
            </intent-filter>
        </service>

        <!--远程 service-->
        <service android:name=".service.TheRemoteService"
            android:process=":FruitLive"
            android:exported="true">
            <intent-filter>
                <action android:name="c com.aidl.myapplication.service.TheRemoteService" />
            </intent-filter>
        </service>

private TheRemoteInterface theRemoteInterface;

    //创建ServiceConnection的匿名类
    ServiceConnection serviceTheRemoteConnection = new ServiceConnection() {
        //重写onServiceConnected()方法和onServiceDisconnected()方法


        //在Activity与Service建立关联时调用
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            //使用BindInterface.Stub.asInterface()方法将传入的IBinder对象传换成了BindInterface对象
            theRemoteInterface = TheRemoteInterface.Stub.asInterface(service);
            try {
                //通过该对象调用在bindInterface文件中定义的接口方法,从而实现跨进程通信
                theRemoteInterface.registerCallback(new TheRemoteCallBack());
            } catch (RemoteException e) {
                e.printStackTrace();
            }
        }

        //在Activity与Service解除关联的时候调用
        @Override
        public void onServiceDisconnected(ComponentName name) {
            try {
                if (null != theRemoteInterface) {
                    theRemoteInterface.unRegisterCallback();
                }
            } catch (RemoteException e) {
                e.printStackTrace();
            }
            theRemoteInterface = null;
        }
    };

具体详情请参考demoService之AIDL的传值

/**
     * service回调
     */
    class TheRemoteCallBack extends com.aidl.myapplication.TheRemoteCallBack.Stub {
        @Override
        public void fruitCallBack(FruitBean mFruitBean) throws RemoteException {

            showFruitUserInfo(mFruitBean.getFruit1(), mFruitBean.getFruit2());
        }

    }

/**
     * activity传值service
     */
 class TheRemoteInterface extends com.aidl.myapplication.TheRemoteInterface.Stub {

        @Override
        public void registerCallback(TheRemoteCallBack callback) throws RemoteException {
            theRemoteCallBack = callback;
        }

        @Override
        public void unRegisterCallback() throws RemoteException {
            theRemoteCallBack = null;
        }
        @Override
        public void sendFruitMessage(String name) throws RemoteException {
            Log.e("sendFruitMessage", "sendFruitMessage name " + name);
        }

    }
