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
vIEw plaincopy to clipboardprint?
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"
