　　AIDL和其他的IDL类似，它允许你定义程序接口，以便客户端与服务器端通过IPC机制交互。在android上面，一个进程一般不能访问另外进程的内存。因此，Android平台将这些跨进程访问的对象分解成操作系统能够识别的简单对象。并为跨应用访问而特殊编排和整理这些对象。用于编排和整理这些对象的代码编写起来十分冗长，所以Android的AIDL提供了相关工具来自动生成这些代码。今天，我们开始AIDL的学习。

简单说明

一，AIDL的定义：

它是一种android内部进程通信接口的描述语言，通过它我们可以定义进程间的通信接口

二、AIDL的开发流程：

定义AIDL文件(先在服务端定义，客户端也要定义，内容跟服务端一样)
服务端实现接口
客户端调用接口

具体的aidl的说明： http://www.cnblogs.com/popapa/p/android_aidl.html

AIDL的简单使用之定义 AIDL 接口

为了测试，我写了aidl服务器端和aidl客户端!

一、创建.aidl文件：IRemoteAIDL.aidl

// IRemoteAIDL.aidl

package com.huhx.linux;

// Declare any non-default types here with import statements

interface IRemoteAIDL {

    int add(int a, int b);

}

二、定义服务类：RemoteService.java

package com.huhx.linux.aidlserver;

import android.app.Service;

import android.content.Intent;

import android.os.IBinder;

import android.os.RemoteException;

import android.util.Log;

import com.huhx.linux.IRemoteAIDL;

public class RemoteService extends Service {

    private final static String TAG = "RemoteService";

    private IRemoteAIDL.Stub binder = new IRemoteAIDL.Stub() {

        @Override

        public int add(int a, int b) throws RemoteException {

            Log.i(TAG, "a = " + a + ", b = " + b);

            return a + b;

        }

    };

    @Override

    public IBinder onBind(Intent intent) {

        return binder;

    }

}

三、在AndroidManifest.xml文件中声明服务：

<service android:name=".RemoteService" android:enabled="true" android:exported="true" />

一、创建与服务器端一样的aidl文件： IRemoteAIDL.aidl

// IRemoteAIDL.aidl

package com.huhx.linux;

// Declare any non-default types here with import statements

interface IRemoteAIDL {

    int add(int a, int b);

}

二、在MainActivity中，得到远程服务并调用它的方法。

package com.huhx.linux.aidlclient;

import android.content.ComponentName;

import android.content.Context;

import android.content.Intent;

import android.content.ServiceConnection;

import android.os.Bundle;

import android.os.IBinder;

import android.os.RemoteException;

import android.support.v7.app.AppCompatActivity;

import android.view.View;

import android.widget.Toast;

import com.huhx.linux.IRemoteAIDL;

public class MainActivity extends AppCompatActivity {

    private IRemoteAIDL iRemoteAIDL;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        binServices();

    }

    private ServiceConnection conn = new ServiceConnection() {

        @Override

        public void onServiceConnected(ComponentName name, IBinder service) {

            iRemoteAIDL = IRemoteAIDL.Stub.asInterface(service);

        }

        @Override

        public void onServiceDisconnected(ComponentName name) {

            iRemoteAIDL = null;

        }

    };

    // 绑定服务

    private void binServices() {

        Intent intent = new Intent();

        intent.setComponent(new ComponentName("com.huhx.linux.aidlserver", "com.huhx.linux.aidlserver.RemoteService"));

        bindService(intent, conn, Context.BIND_AUTO_CREATE);

    }

    // 处理相加的方法

    public void addMethod(View view) {

        try {

            int result = iRemoteAIDL.add(3, 4);

            Toast.makeText(MainActivity.this, "3 + 4 = " + result, Toast.LENGTH_SHORT).show();

        } catch (RemoteException e) {

            e.printStackTrace();

        }

    }

}

三、根据aidl文件，android生成的接口如下(可以不关注)：

/*

 * This file is auto-generated.  DO NOT MODIFY.

 * Original file: J:\\android\\andridtest\\andridtest\\2016-02-29\\BaseTest8\\aidlclient\\src\\main\\aidl\\com\\huhx\\linux\\IRemoteAIDL.aidl

 */

package com.huhx.linux;

// Declare any non-default types here with import statements

public interface IRemoteAIDL extends android.os.IInterface

{

/** Local-side IPC implementation stub class. */

public static abstract class Stub extends android.os.Binder implements com.huhx.linux.IRemoteAIDL

{

private static final java.lang.String DESCRIPTOR = "com.huhx.linux.IRemoteAIDL";

/** Construct the stub at attach it to the interface. */

public Stub()

{

this.attachInterface(this, DESCRIPTOR);

}

/**

 * Cast an IBinder object into an com.huhx.linux.IRemoteAIDL interface,

 * generating a proxy if needed.

 */

public static com.huhx.linux.IRemoteAIDL asInterface(android.os.IBinder obj)

{

if ((obj==null)) {

return null;

}

android.os.IInterface iin = obj.queryLocalInterface(DESCRIPTOR);

if (((iin!=null)&&(iin instanceof com.huhx.linux.IRemoteAIDL))) {

return ((com.huhx.linux.IRemoteAIDL)iin);

}

return new com.huhx.linux.IRemoteAIDL.Stub.Proxy(obj);

}

@Override public android.os.IBinder asBinder()

{

return this;

}

@Override public boolean onTransact(int code, android.os.Parcel data, android.os.Parcel reply, int flags) throws android.os.RemoteException

{

switch (code)

{

case INTERFACE_TRANSACTION:

{

reply.writeString(DESCRIPTOR);

return true;

}

case TRANSACTION_add:

{

data.enforceInterface(DESCRIPTOR);

int _arg0;

_arg0 = data.readInt();

int _arg1;

_arg1 = data.readInt();

int _result = this.add(_arg0, _arg1);

reply.writeNoException();

reply.writeInt(_result);

return true;

}

}

return super.onTransact(code, data, reply, flags);

}

private static class Proxy implements com.huhx.linux.IRemoteAIDL

{

private android.os.IBinder mRemote;

Proxy(android.os.IBinder remote)

{

mRemote = remote;

}

@Override public android.os.IBinder asBinder()

{

return mRemote;

}

public java.lang.String getInterfaceDescriptor()

{

return DESCRIPTOR;

}

@Override public int add(int a, int b) throws android.os.RemoteException

{

android.os.Parcel _data = android.os.Parcel.obtain();

android.os.Parcel _reply = android.os.Parcel.obtain();

int _result;

try {

_data.writeInterfaceToken(DESCRIPTOR);

_data.writeInt(a);

_data.writeInt(b);

mRemote.transact(Stub.TRANSACTION_add, _data, _reply, 0);

_reply.readException();

_result = _reply.readInt();

}

finally {

_reply.recycle();

_data.recycle();

}

return _result;

}

}

static final int TRANSACTION_add = (android.os.IBinder.FIRST_CALL_TRANSACTION + 0);

}

public int add(int a, int b) throws android.os.RemoteException;

}

IRemoteAIDL.java

AIDL的简单使用之通过 IPC 传递对象

如果要跨进程传递某个类，可以通过 IPC 接口来实现。不过，请务必确保在 IPC 通道的对端可以识别该类的代码，该类必须支持 Parcelable 接口。支持 Parcelable 接口非常重要，因为这使得 Android 系统可将对象分解为能够跨进程组装的原生数据。

可按以下步骤创建支持 Parcelable 协议的类：

必须实现Parcelable 接口。
实现 writeToParcel 方法，参数为当前对象的状态，并写入一个 Parcel中。
在类中添加一个名为 CREATOR 的静态成员变量，即为一个实现了 Parcelable.Creator 接口的对象。
最后，创建 .aidl 文件，声明该 Parcelable 类（如下述 Rect.aidl 文件所示）。

如果采用自定义编译方式，请不要把 .aidl 文件加入编译项目。与 C 语言的头文件类似， .aidl 文件不会被编译。AIDL 利用上述方法和成员变量来分解和组装对象。

alt="" />

一、修改的IRemoteAIDL.aidl文件：

// IRemoteAIDL.aidl

package com.huhx.linux;

import com.huhx.linux.Person;

interface IRemoteAIDL {

    int add(int a, int b);

    List<Person> addPerson(in Person person);

}

二、增加Person.aidl文件：

// Person.aidl

package com.huhx.linux;

parcelable Person;

三、增加Person.java文件，注意它的位置是com.huhx.linux;

package com.huhx.linux;

import android.os.Parcel;

import android.os.Parcelable;

/**

 * Created by Linux on 2016/5/9.

 */

public class Person implements Parcelable {

    public String username;

    public String password;

    public Person(String username, String password) {

        this.username = username;

        this.password = password;

    }

    protected Person(Parcel in) {

        username = in.readString();

        password = in.readString();

    }

    public static final Creator<Person> CREATOR = new Creator<Person>() {

        @Override

        public Person createFromParcel(Parcel in) {

            return new Person(in);

        }

        @Override

        public Person[] newArray(int size) {

            return new Person[size];

        }

    };

    @Override

    public int describeContents() {

        return 0;

    }

    @Override

    public void writeToParcel(Parcel dest, int flags) {

        dest.writeString(username);

        dest.writeString(password);

    }

}

这里，之前是放在com.huhx.linux.aidlclient下的，但是处理起来总是报错。不知道是否要求aidl的包名与序列化类的包名一致？

三、修改RemoteService.java文件

public class RemoteService extends Service {

    List<Person> persons = new ArrayList<>();

    private final static String TAG = "RemoteService";

    private IRemoteAIDL.Stub binder = new IRemoteAIDL.Stub() {

        @Override

        public int add(int a, int b) throws RemoteException {

            Log.i(TAG, "a = " + a + ", b = " + b);

            return a + b;

        }

        @Override

        public List<Person> addPerson(Person person) throws RemoteException {

            persons.add(person);

            return persons;

        }

    };

    @Override

    public IBinder onBind(Intent intent) {

        return binder;

    }

aidl文件以及Person类与服务器端的一样，这里不做说明，在MainActivity中增加测试的方法。

// 添加一个方法

public void addPerson(View view) {

    Person person1 = new Person("Linux", "123456");

    Person person2 = new Person("Huhx", "654321");

    int length = 0;

    try {

        iRemoteAIDL.addPerson(person1);

        length = iRemoteAIDL.addPerson(person2).size();

        Toast.makeText(MainActivity.this, "list size: " + length, Toast.LENGTH_SHORT).show();

    } catch (RemoteException e) {

        e.printStackTrace();

    }

}
