类实现Parcelable接口在Intent中传递

类实现了Parcelable接口就可以在Intent中传递   只要在类的定义中实现Parcelable接口

代码

package entity;

import android.os.Parcel;
import android.os.Parcelable;

public class Person implements Parcelable {

    private int id;
    private String name;
    private String pass;

    public Person() {
        super();
        // TODO Auto-generated constructor stub
    }

    public Person(int id, String name, String pass) {
        super();
        this.id = id;
        this.name = name;
        this.pass = pass;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPass() {
        return pass;
    }

    public void setPass(String pass) {
        this.pass = pass;
    }

    @Override
    public String toString() {
        return "Person [id=" + id + ", name=" + name + ", pass=" + pass + "]";
    }
         //----------实现内容描述
    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
       //-------------写入到包中    注意 写入顺序 
    @Override
    public void writeToParcel(Parcel dest, int flags) {
        // TODO Auto-generated method stub
        dest.writeInt(id);
        dest.writeString(name);
        dest.writeString(pass);

    }
    // 添加一个静态成员,名为CREATOR,该对象实现了Parcelable.Creator接口 
    public static final Parcelable.Creator<Person> CREATOR = new Creator<Person>() {

        @Override
        public Person[] newArray(int size) {
            // TODO Auto-generated method stub
            return new Person[size];
        }

        @Override
        public Person createFromParcel(Parcel source) {
            // 从Parcel中读取数据，返回person对象    --------------按顺序读
            return new Person(source.readInt(), source.readString(),
                    source.readString());
        }
    };

}
