1 实现序列化接口

package com.example.zcjfq2;import java.io.Serializable;public class SerInfo implements Serializable {    private String Id;    private String OldDocName;    public SerInfo(String id, String olddocname){        this.Id = id;        this.OldDocName = olddocname;    }    public String getId() {        return Id;    }    public String getOldDocName() {        return OldDocName;    }    public void setId(String id) {        this.Id = id;    }    public void setOldDocName(String olddocname) {        this.OldDocName = olddocname;    }}

2 序列化

 ArrayList listObj = new ArrayList();                                for (int i =0;i

ArrayList oldDocName = (ArrayList) getIntent().getSerializableExtra("oldDocName");String id = oldDocName.get(1).getId();        String name = oldDocName.get(1).getOldDocName();
