Android實現Parcelable對象序列化的實例

bundle.putParcelable可以實現傳遞對象，但是這個對象的類必須實現Parcelable接口才能夠使用。

下面是一個簡單的在Activity之間傳遞對象的例子。

parcel實現參數的序列化，把類對象序列 化為齊位的二進制流，提高傳輸的效率。

Parcelable類。最主要的類，也就是我們要傳送的對象的類，需要實現Parcelable接口。

import 

android.os.Parcel;    
import android.os.Parcelable;    
        
public class BenParcelable implements Parcelable {    
        
    public String name;    
        
    public int age;    
        
    public String profession;    
        
    public BenParcelable(String name, int age, String profession) {    
        this.name = name;    
        this.age = age;    
        this.profession = profession;    
    }    
        
    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;    
    }    
        
    public String getprofession() {    
        return profession;    
    }    
        
    public void setprofession(String profession) {    
        this.profession = profession;    
    }    
        
    @Override
    public int describeContents() {    
        return 0;    
    }    
        
    @Override
    public void writeToParcel(Parcel parcel, int flag) {    
        parcel.writeString(name);    
        parcel.writeInt(age);    
        parcel.writeString(profession);    
    }    
        
    public static final Creator<BenParcelable> CREATOR = new Creator<BenParcelable>

() {    
        public BenParcelable createFromParcel(Parcel in) {    
            return new BenParcelable(in);    
        }    
        
        public BenParcelable[] newArray(int size) {    
            return new BenParcelable[size];    
        }    
    };    
        
    private BenParcelable(Parcel in) {    
        name = in.readString();    
        age = in.readInt();    
        profession = in.readString();    
    }
