android之间传递多个对象  IPC也是…

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<?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:

1. packagecom.tutor.objecttran;    
2. importjava.io.Serializable;    
3. publicclassPerson implementsSerializable {    
4.    privatestaticfinallongserialVersionUID = -7060210544600464481L;     
5.    privateString name;    
6.    privateintage;    
7.    publicString getName() {    
8.        returnname;    
9.    }    
10.    publicvoidsetName(String name) {    
11.        this.name = name;    
12.    }    
13.    publicintgetAge() {    
14.        returnage;    
15.    }    
16.    publicvoidsetAge(intage) {    
17.        this.age = age;    
18.    }    
19.        
20. }

Book.java: 

1. packagecom.tutor.objecttran;    
2. importandroid.os.Parcel;    
3. importandroid.os.Parcelable;    
4. publicclassBook implementsParcelable {    
5.    privateString bookName;    
6.    privateString author;    
7.    privateintpublishTime;    
8.        
9.    publicString getBookName() {    
10.        returnbookName;    
11.    }    
12.    publicvoidsetBookName(String bookName) {    
13.        this.bookName = bookName;    
14.    }    
15.    publicString getAuthor() {    
16.        returnauthor;    
17.    }    
18.    publicvoidsetAuthor(String author) {    
19.        this.author = author;    
20.    }    
21.    publicintgetPublishTime() {    
22.        returnpublishTime;    
23.    }    
24.    publicvoidsetPublishTime(intpublishTime) {    
25.        this.publishTime = publishTime;    
26.    }    
27.        
28.    publicstaticfinalParcelable.Creator<Book> CREATOR = newCreator<Book>() {    
29.        publicBook createFromParcel(Parcel source) {    
30.            Book mBook = newBook();    
31.            mBook.bookName = source.readString();    
32.            mBook.author = source.readString();    
33.            mBook.publishTime = source.readInt();    
34.            returnmBook;    
35.        }    
36.        publicBook[] newArray(intsize) {    
37.            returnnewBook[size];    
38.        }    
39.    };    
40.        
41.    publicintdescribeContents() {    
42.        return0;    
43.    }    
44.    publicvoidwriteToParcel(Parcel parcel, intflags) {    
45.        parcel.writeString(bookName);    
46.        parcel.writeString(author);    
47.        parcel.writeInt(publishTime);    
48.    }    
49. }

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:
