小编use*_*762的帖子

所以我在logcat中得到这个:

java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = com.resources.student_list.Student)

我知道这意味着我的学生班不是可序列化的,但是,这是我的学生班:

import java.io.Serializable;


public class Student implements Comparable<Student>,  Serializable{

    private static final long serialVersionUID = 1L;
    private String firstName, lastName;
    private DSLL<Grade> gradeList; 

    public Student() {
        firstName = "";
        lastName = "";
        gradeList = new DSLL<Grade>();
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    } …
