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);
  mHorizontalWeekLayout.addView(getWeekVerticalLine());
 }
 addView(mHorizontalWeekLayout);
 addView(getWeekTransverseLine());
 addView(mVerticalWeekLaout);
 addView(getWeekTransverseLine());
 }
