基于android的学生考勤系源代码

基于Android的学生考勤系统的源代码包含了多个部分，其中包括学生信息管理、课程管理、考勤记录管理等功能。以下是一个简单的示例代码：

1. 学生信息管理：

public class Student {
    private String name;
    private int studentId;
    
    public Student(String name, int studentId) {
        this.name = name;
        this.studentId = studentId;
    }
    
    public String getName() {
        return name;
    }
    
    public int getStudentId() {
        return studentId;
    }
}

2. 课程管理：

public class Course {
    private String courseName;
    private List<Student> students;
    
    public Course(String courseName) {
        this.courseName = courseName;
        students = new ArrayList<>();
    }
    
    public void addStudent(Student student) {
        students.add(student);
    }
    
    public void removeStudent(Student student) {
        students.remove(student);
    }
    
    public List<Student> getStudents() {
        return students;
    }
}

3. 考勤记录管理：

public class AttendanceRecord {
    private Course course;
    private Date date;
    private List<Student> presentStudents;
    
    public AttendanceRecord(Course course, Date date) {
        this.course = course;
        this.date = date;
        presentStudents = new ArrayList<>();
    }
    
    public void markAttendance(Student student) {
        presentStudents.add(student);
    }
    
    public void cancelAttendance(Student student) {
        presentStudents.remove(student);
    }
    
    public List<Student> getPresentStudents() {
        return presentStudents;
    }
}

以上是一个简单的基于Android的学生考勤系统的源代码示例。实际开发中还需要添加界面设计、数据库操作等相关功能，以实现完整的学生考勤系统。
