【整理】使用AIDL跨进程传递复杂对象的实践例子

首先定义对象类，并实现Parcelable接口，实现接口内的几个方法，看代码，Person.java

package com.example.u3.aidltest;

import android.os.Parcel;
import android.os.Parcelable;

/**
 * Created by U3 on 2015/3/11.
 */
public class Person implements Parcelable {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPass() {
        return pass;
    }

    public void setPass(String pass) {
        this.pass = pass;
    }

    private String pass;
    @Override
    public int describeContents() {
        return 0;
    }
 
    public static final Creator<Person> CREATOR = new Creator<Person>() {
        @Override
        public Person createFromParcel(Parcel source) {
            return new Person(source);
        }

        @Override
        public Person[] newArray(int size) {
            return new Person[size];
        }
    };//用于创建
    public Person()//测试用
    {
        name = "hel";
        pass = "213";
    }
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeString(pass);
    }
   private Person(Parcel in)//必须与上面的写入顺序相同，否则值会错误
    {
       name = in.readString();
        pass = in.readString();
    }


}

然后，新建两个AIDL文件，一个声明接口一个声明上面的类，声明类的AIDL名字必须与类相同，看代码

Person.aidl

package com.example.u3.aidltest;//包名
parcelable Person;

myaidl.aidl

// myaidl.aidl
package com.example.u3.aidltest;

// Declare any non-default types here with import statements
import com.example.u3.aidltest.Person;//需要先引入
interface myaidl {
    /**
     * Demonstrates some basic types that you can use as parameters
     * and return values in AIDL.
     */
    Person getperson(in Person s);
}

然后在服务中使用自动生成的类，实现方法，见代码

package com.example.u3.aidltest;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;

/**
 * Created by U3 on 2015/3/11.
 */
public class Server extends Service {
    class My extends myaidl.Stub {//继承自动生成的类，实现方法
        @Override
        public Person getperson(Person s) throws RemoteException {

            Log.v("sk", s.getName()+" "+s.getPass());
            s.setName("hi!!!!");
            return s;
        }
    }

    @Override
    public IBinder onBind(Intent intent) {
        return new My();
    }
}

然后在客户端，复制AIDL文件所在包和Person以及他的包

两边的结构图如下
