Android中Intent传递对象的两种方法(Serializable,Parcelable)

Android中Intent中如何传递对象,就我目前所知道的有两种方法，一种是Bundle.putSerializable(Key,Object);另一种是Bundle.putParcelable(Key, Object);当然这些Object是有一定的条件的，前者是实现了Serializable接口，而后者是实现了Parcelable接口，为了让大家更容易理解我还是照常写了一个简单的Demo,大家就一步一步跟我来吧！

第一步:新建一个Android工程命名为ObjectTranDemo(类比较多哦!)目录结构如下图:

第二步:修改main.xml布局文件(这里我增加了两个按钮)代码如下

to clipboardprint?<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Welcome to Mr wei's blog."
    />
<Button
    android:id="@+id/button1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Serializable"
/>
<Button
    android:id="@+id/button2"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Parcelable"
/>
</LinearLayout>

第三步:新建两个类一个是Person.java实现Serializable接口，另一个Book.java实现Parcelable接口，代码分别如下:

Person.java:

to clipboardprint?package com.tutor.objecttran;
import java.io.Serializable;
public class Person implements Serializable {
    private static final long serialVersionUID = -7060210544600464481L;
    private String name;
    private int age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }

}

Book.java:

to clipboardprint?package com.tutor.objecttran;
import android.os.Parcel;
import android.os.Parcelable;
public class Book implements Parcelable {
    private String bookName;
    private String author;
    private int publishTime;

    public String getBookName() {
        return bookName;
    }
    public void setBookName(String bookName) {
        this.bookName = bookName;
    }
    public String getAuthor() {
        return author;
    }
    public void setAuthor(String author) {
        this.author = author;
    }
    public int getPublishTime() {
        return publishTime;
    }
    public void setPublishTime(int publishTime) {
        this.publishTime = publishTime;
    }

    public static final Parcelable.Creator<Book> CREATOR = new Creator<Book>() {
        public Book createFromParcel(Parcel source) {
            Book mBook = new Book();
            mBook.bookName = source.readString();
            mBook.author = source.readString();
            mBook.publishTime = source.readInt();
            return mBook;
        }
        public Book[] newArray(int size) {
            return new Book[size];
        }
    };

    public int describeContents() {
        return 0;
    }
    public void writeToParcel(Parcel parcel, int flags) {
        parcel.writeString(bookName);
        parcel.writeString(author);
        parcel.writeInt(publishTime);
    }
}

第四步:修改ObjectTranDemo.java,并且新建两个Activity,一个是ObjectTranDemo1.java,别一个是ObjectTranDemo2.java.分别用来显示Person对像数据，和Book对象数据:,代码分别如下：

ObjectTranDemo.java:

to clipboardprint?package com.tutor.objecttran;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class ObjectTranDemo extends Activity implements OnClickListener {

    private Button sButton,pButton;
    public final static String SER_KEY = "com.tutor.objecttran.ser";
    public final static String PAR_KEY = "com.tutor.objecttran.par";
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        setupViews();

    }

    //我的一贯作风呵呵
    public void setupViews(){&nb
