在Android中intent传递对象主要有2种方式分别是，Bundle.putSerializable(Key,Object)和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，以下是我为大家做的一个实例

首先我们建立一个工程项目命名为：ObjectTestDemo

然后我们再修改main.xml布局文件，主要增加2个按钮

复制代码 代码如下:

< ?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 Jesson'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>

< ?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 jesson'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>

[code]

接下来我们开始对工程进行实现，分别建立Person.java实现Serializable接口，另一个Book.java实现Parcelable接口

[code]

package com.test.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;

}

}

复制代码 代码如下:

package com.test.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;

}

}

复制代码 代码如下:

package com.test.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 CREATOR = new Creator() {

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);

}

}

复制代码 代码如下:

package com.test.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 CREATOR = new Creator() {

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);

}

}

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

复制代码 代码如下:

package com.test.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();

}

public void setupViews(){

sButton = (Button)findViewById(R.id.button1);

pButton = (Button)findViewById(R.id.button2);

sButton.setOnClickListener(this);

pButton.setOnClickListener(this);

}

//Serializeable传递对象的方法

public void SerializeMethod(){

Person mPerson = new Person();

mPerson.setName("frankie");

mPerson.setAge(25);

Intent mIntent = new Intent(this,ObjectTranDemo1.class);

Bundle mBundle = new Bundle();

mBundle.putSerializable(SER_KEY,mPerson);

mIntent.putExtras(mBundle);

startActivity(mIntent);

}

//Pacelable传递对象方法

public void PacelableMethod(){

Book mBook = new Book();

mBook.setBookName("Android Tutor");

mBook.setAuthor("Frankie");

mBook.setPublishTime(2010);

Intent mIntent = new Intent(this,ObjectTranDemo2.class);

Bundle mBundle = new Bundle();

mBundle.putParcelable(PAR_KEY, mBook);

mIntent.putExtras(mBundle);

startActivity(mIntent);

}

//铵钮点击事件响应

public void onClick(View v) {

if(v == sButton){

SerializeMethod();

}else{

PacelableMethod();

}

}

}

代码

复制代码 代码如下:

package com.test.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();

}

public void setupViews(){

sButton = (Button)findViewById(R.id.button1);

pButton = (Button)findViewById(R.id.button2);

sButton.setOnClickListener(this);

pButton.setOnClickListener(this);

}

//Serializeable传递对象的方法

public void SerializeMethod(){

Person mPerson = new Person();

mPerson.setName("frankie");

mPerson.setAge(25);

Intent mIntent = new Intent(this,ObjectTranDemo1.class);

Bundle mBundle = new Bundle();

mBundle.putSerializable(SER_KEY,mPerson);

mIntent.putExtras(mBundle);

startActivity(mIntent);

}

//Pacelable传递对象方法

public void PacelableMethod(){

Book mBook = new Book();

mBook.setBookName("Android Tutor");

mBook.setAuthor("Frankie");

mBook.setPublishTime(2010);

Intent mIntent = new Intent(this,ObjectTranDemo2.class);

Bundle mBundle = new Bundle();

mBundle.putParcelable(PAR_KEY, mBook);

mIntent.putExtras(mBundle);

startActivity(mIntent);

}

//铵钮点击事件响应

public void onClick(View v) {

if(v == sButton){

SerializeMethod();

}else{

PacelableMethod();

}

}

}

代码

复制代码 代码如下:

package com.test.tutor.objecttran;

import android.app.Activity;

import android.os.Bundle;

import android.widget.TextView;

public class ObjectTranDemo1 extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

TextView mTextView = new TextView(this);

Person mPerson = (Person)getIntent().getSerializableExtra(ObjectTranDemo.SER_KEY);

mTextView.setText("You name is: " + mPerson.getName() + ""+

"You age is: " + mPerson.getAge());

setContentView(mTextView);

}

代码

复制代码 代码如下:

package com.test.tutor.objecttran;

import android.app.Activity;

import android.os.Bundle;

import android.widget.TextView;

public class ObjectTranDemo1 extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

TextView mTextView = new TextView(this);

Person mPerson = (Person)getIntent().getSerializableExtra(ObjectTranDemo.SER_KEY);

mTextView.setText("You name is: " + mPerson.getName() + ""+

"You age is: " + mPerson.getAge());

setContentView(mTextView);

}

}

代码

复制代码 代码如下:

package com.test.tutor.objecttran;

import android.app.Activity;

import android.os.Bundle;

import android.widget.TextView;

public class ObjectTranDemo2 extends Activity {

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

TextView mTextView = new TextView(this);

Book mBook = (Book)getIntent().getParcelableExtra(ObjectTranDemo.PAR_KEY);

mTextView.setText("Book name is: " + mBook.getBookName()+""+

"Author is: " + mBook.getAuthor() + "" +

"PublishTime is: " + mBook.getPublishTime());setContentView(mTextView);

}

}

复制代码 代码如下:

package com.test.tutor.objecttran;

import android.app.Activity;

import android.os.Bundle;

import android.widget.TextView;

public class ObjectTranDemo2 extends Activity {

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

TextView mTextView = new TextView(this);

Book mBook = (Book)getIntent().getParcelableExtra(ObjectTranDemo.PAR_KEY);

mTextView.setText("Book name is: " + mBook.getBookName()+""+

"Author is: " + mBook.getAuthor() + "" +

"PublishTime is: " + mBook.getPublishTime());

setContentView(mTextView);

}

}

下面是最重要的环节：修改AndroidManifest.xml文件(将两个新增的Activity，ObjecttestDemo1,ObjecttestDemo2)申明一下代码如下(第14，15行):

代码

复制代码 代码如下:

< ?xml version="1.0" encoding="utf-8"?>

< manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.test.tutor.objecttran"

android:versionCode="1"
