Android自定义View实现课程表表格

自己闲下来时间写的一个课表控件，使用的自定义linearlayout，里面view都是用代码实现的，最终效果如下图，写的可能有问题希望多多指点

创建一个自定义linearlayout 控件用来装载课程的信息和课程的周数，和节数大概的布局三这样的

根据上面的看来觉得总体布局我分了两个 上面的星期是一个 下面的节数和格子是一个  总体使用vertical  而单独内部者使用了horizontal布局  中间使用了两种布局线条 是这样的

/**
 * 横的分界线
 *
 * @return
 */
 private view getweektransverseline() {
 textview mweekline = new textview(getcontext());
 mweekline.setbackgroundcolor(getresources().getcolor(r.color.view_line));
 mweekline.setheight(timetablelineheight);
 mweekline.setwidth(layoutparams.fill_parent);
 return mweekline;
 }
 
 
 /**
 * 竖向分界线
 *
 * @return
 */
 private view getweekverticalline() {
 textview mweekline = new textview(getcontext());
 mweekline.setbackgroundcolor(getresources().getcolor(r.color.view_line));
 mweekline.setheight(dip2px(timetableweeknameheight));
 mweekline.setwidth((timetablelineheight));
 return mweekline;
 }

下面就看其它的view 

那就从上到下开始先看星期的布局

 private void initview() {
 
 mhorizontalweeklayout = new linearlayout(getcontext());
 mhorizontalweeklayout.setorientation(horizontal);
 
 mverticalweeklaout = new linearlayout(getcontext());
 mverticalweeklaout.setorientation(horizontal);
 //表格
 for (int i = 0; i <= weeknum; i++) {
  switch (i) {
  case 0:
   //课表出的0,0格子 空白的
   textview mtime = new textview(getcontext());
   mtime.setheight(dip2px(timetableweeknameheight));
   mtime.setwidth((dip2px(timetablenumwidth)));
   mhorizontalweeklayout.addview(mtime);
 
   //绘制1~maxnum
   linearlayout mmonday = new linearlayout(getcontext());
   viewgroup.layoutparams mm = new viewgroup.layoutparams(dip2px(timetablenumwidth), dip2px(maxnum * timetableheight) + maxnum * 2);
   mmonday.setlayoutparams(mm);
   mmonday.setorientation(vertical);
   for (int j = 1; j <= maxnum; j++) {
   textview mnum = new textview(getcontext());
   mnum.setgravity(gravity.center);
   mnum.settextcolor(getresources().getcolor(r.color.text_color));
   mnum.setheight(dip2px(timetableheight));
   mnum.setwidth(dip2px(timetablenumwidth));
   mnum.settextsize(14);
   mnum.settext(j + "");
   mmonday.addview(mnum);
   mmonday.addview(getweektransverseline());
   }
   mverticalweeklaout.addview(mmonday);
   break;
  case 1:
  case 2:
  case 3:
  case 4:
  case 5:
  case 6:
  case 7:
   // 设置显示星期一 到星期天
   linearlayout mhoriview = new linearlayout(getcontext());
   mhoriview.setorientation(vertical);
   textview mweekname = new textview(getcontext());
   mweekname.settextcolor(getresources().getcolor(r.color.text_color));
   mweekname.setwidth(((getviewwidth() - dip2px(timetablenumwidth))) / weeknum);
   mweekname.setheight(dip2px(timetableweeknameheight));
   mweekname.setgravity(gravity.center);
   mweekname.settextsize(16);
   mweekname.settext(weekname[i - 1]);
   mhoriview.addview(mweekname);
   mhorizontalweeklayout.addview(mhoriview);
 
   list<timetablemodel> mlistmon = new arraylist<>();
   //遍历出星期1~7的课表
   for (timetablemodel timetablemodel : mlisttimetable) {
   if (timetablemodel.getweek() == i) {
    mlistmon.add(timetablemodel);
   }
   }
   //添加
   linearlayout mlayout = gettimetableview(mlistmon, i);
   mlayout.setorientation(vertical);
   viewgroup.layoutparams linearparams = new viewgroup.layoutparams((getviewwidth() - dip2px(20)) / weeknum, layoutparams.fill_parent);
   mlayout.setlayoutparams(linearparams);
   mlayout.setweightsum(1);
   mverticalweeklaout.addview(mlayout);
   break;
 
  default:
   break;
  }
  textview l = new textview(getcontext());
  l.setheight(dip2px(timetableheight * maxnum) + maxnum * 2);
  l.setwidth(2);
  l.setbackgroundcolor(getresources().getcolor(r.color.view_line));
  mverticalweeklaout.addview(l);
