Android课程表的设计开发

android课程表的设计开发

导语

实现了教务系统中课程的导入，分类显示课程。学期的修改，增加，修改。课程按照周的显示。课程修改上课星期和上课周。上课课程的自动归类。

一、主要功能界面

开发过程

一开始因为毕设有关课程表的要求不明，主要就是利用jsoup拉取学校教务管理系统的课程数据进行课程表界面的填充显示，并不能课程的个性化调整。
后来重新调整了需求，参考了超级课程表的功能。重新设计了实体类，利用bmob移动端云作为爬取到的数据的数据服务器进行了重新的开发。

主要代码

1、课程实体类

package com.mangues.coursemanagement.bean;

import java.io.Serializable;

import java.util.regex.Matcher;

    private String courseRoom = "";   //教室
    private String courseTeacher = "";  //老师
    //private String courseWeekNumber = "0";
    private ArrayList<Integer> courseWeekNumber = new ArrayList<>(); //周数
    private int courseWeek = 0;   //星期几上课
    private int courseLow = 0;   //第几排
    private int courseSection = 0;    //延续几节课
    //private String courseSection = "12";   //第几节上课1,2,12(2节课)
    //private String courseIn = "3";    //单双周    1(单),2(双),3(全)

2、课程归类处理

    //按天查询数据
    private void getDayDate(List<CourseBean> list){
        boolean boo = SaveUtil.getSharedPreferencesSwitch(mContext);
        ArrayList<CourseBean> integerA = new ArrayList<>();
        if (boo){
            if (weekNum!=-1){
                for (int l=0;l<list.size();l++){     //去除
                    ArrayList<Integer> integerArrayList = list.get(l).getCourseWeekNumber();
                    if (!integerArrayList.contains(weekNum)){  //不包含，就是不是本周，去除
                        integerA.add(list.get(l));
                    }
                }
                    list.removeAll(integerA);


            }
        }





        List<CourseBean> list1  = null;
        Map<Integer,List<CourseBean>> map = new HashMap<>();

        for (CourseBean be :list) {


            Integer weekNum = be.getCourseWeek();
            if (map.containsKey(weekNum)){  //有数据
                list1 = map.get(weekNum);
            }else {
                list1 = new ArrayList<>();
                map.put(weekNum,list1);
            }
            list1.add(be);
        }

        ArrayList<CourseBeanMap> ls = new ArrayList<>();

        //按星期几处理
        for (Map.Entry<Integer,List<CourseBean>> entry : map.entrySet()) {
            List<CourseBeanMap>  mapw = handleRepeat(entry.getValue(),entry.getKey());
                ls.addAll(mapw);


        }

        //本地存储存储使用
        TimeTableBmob bmob = new TimeTableBmob();
        bmob.setStudentId(CourseApplication.getInstance().getUserInfo().getStudentId());
        bmob.setCourseList(ls);
        bmob.setTerm(dataTerm);
        bmob.setYear(dataYear);
        CourseApplication.getInstance().setTimeTableBmob(bmob);

        dataBack.onDataBack(ls);
    }




    //处理重复
    private List<CourseBeanMap>  handleRepeat(List<CourseBean> list,Integer weekNum){

        Collections.sort(list,new Comparator<CourseBean>(){
            public int compare(CourseBean arg0, CourseBean arg1) {
                Integer year1 = arg0.getCourseLow();
                Integer year2 = arg1.getCourseLow();
                return year1.compareTo(year2);
            }
        });



        List<CourseBeanMap> listKey = new ArrayList<>();
        List<String> liststr = new ArrayList<>();

        int size = list.size();

            for (int h=0;h<list.size();h++){
                CourseBean bean = list.get(h);
                Integer low = bean.getCourseLow();
                Integer sesson = bean.getCourseSection();
                Boolean isAdd = false;

                for (int kk=0;kk<listKey.size();kk++){


                    String key = liststr.get(kk);
                    String[] keys = key.split("-");//
                    Integer low1 =Integer.parseInt(keys[0]);//3
                    Integer sesson1 =Integer.parseInt(keys[1]);//2


                    if ((low1+sesson1-1)>=low){   //包含在内
                        isAdd = true;
                        CourseBeanMap cousermap = listKey.get(kk);
                        cousermap.setCourseLow(low1);
                        cousermap.setCourseWeek(weekNum);
                        cousermap.setCourseSection(sesson+low-low1);
                        liststr.set(kk,low1+"-"+(sesson+low-low1));//修改key值
                        cousermap.add(bean);
                    }
                }


                if (isAdd==false){
                    CourseBeanMap cousermap = new CourseBeanMap();
                    cousermap.setCourseLow(low);
                    cousermap.setCourseWeek(weekNum);
                    cousermap.setCourseSection(sesson);
                    cousermap.add(bean);
                    listKey.add(cousermap);
                    liststr.add(low+"-"+sesson);
                }
            }


        return listKey;
    }

3.课程表界面

利用了网上找到的一段代码进行部分修改完成

    //初始化课程表界面
  private void initTable() {
        // 获得列头的控件
        empty = (TextView) this.findViewById(R.id.test_empty);
        monColum = (TextView) this.findViewById(R.id.test_monday_course);
        tueColum = (TextView) this.findViewById(R.id.test_tuesday_course);

        thrusColum = (TextView) this.findViewById(R.id.test_thursday_course);
        friColum = (TextView) this.findViewById(R.id.test_friday_course);
        satColum = (TextView) this.findViewById(R.id.test_saturday_course);
        sunColum = (TextView) this.findViewById(R.id.test_sunday_course);
        course_table_layout = (RelativeLayout) this
                .findViewById(R.id.test_course_rl);
        course_table_layout.removeAllViews();  //清楚页面数据
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        // 屏幕宽度
        int width = dm.widthPixels;
        // 平均宽度
        int aveWidth = width / 8;
        // 第一个空白格子设置为25宽
        empty.setWidth(aveWidth * 3 / 4);
        monColum.setWidth(aveWidth * 33 / 32 + 1);
        tueColum.setWidth(aveWidth * 33 / 32 + 1);
        wedColum.setWidth(aveWidth * 33 / 32 + 1);
        thrusColum.setWidth(aveWidth * 33 / 32 + 1);
        friColum.setWidth(aveWidth * 33 / 32 + 1);
        satColum.setWidth(aveWidth * 33 / 32 + 1);
        sunColum.setWidth(aveWidth * 33 / 32 + 1);
        this.screenWidth = width;
        this.aveWidth = aveWidth;
        int height = dm.heightPixels;
        gridHeight = height / 12;
        // 设置课表界面
        // 动态生成12 * maxCourseNum个textview
        for (int i = 1; i <= 12; i++) {

            for (int j = 1; j <= 8; j++) {

                TextView tx = new TextView(mContext);
                tx.setId((i - 1) * 8 + j);
                // 除了最后一列，都使用course_text_view_bg背景（最后一列没有右边框）
                if (j < 8)
                    tx.setBackgroundDrawable(mContext.getResources()
