Android 价格日历-第一弹
查找过各种技术文档，发现android价格日历这一部分貌似还是空白，我就把真实项目中的代码给大家分析一下
有兴趣的朋友可以去下载源码

一、先给大家看效果图，左右滑动翻月，如果在某天之前没有可售的日子，那么会提示“xxxx-xx-xx之前无...”，并不能翻月。颜色，文字都可以自定义，
二、接下来我们讲解代码
直接上价格日历的控件，下面是关键代码
/** * 填充日历(包含日期、标记、背景等) */ private void setCalendarDate() { // 根据日历的日子获取这一天是星期几 int weekday = calendarday.getDay(); // 每个月第一天 int firstDay = 1; // 每个月中间号,根据循环会自动++ int day = firstDay; // 每个月的最后一天 int lastDay = getDateNum(calendarday.getYear(), calendarday.getMonth()); // 下个月第一天 int nextMonthDay = 1; int lastMonthDay = 1; // 填充每一个空格 for (int i = 0; i < ROWS_TOTAL; i++) { for (int j = 0; j < COLS_TOTAL; j++) { // 这个月第一天不是礼拜天,则需要绘制上个月的剩余几天 if (i == 0 && j == 0 && weekday != 0) { int year = 0; int month = 0; int lastMonthDays = 0; // 如果这个月是1月，上一个月就是去年的12月 if (calendarday.getMonth() == 0) { year = calendarday.getYear() - 1; month = Calendar.DECEMBER; } else { year = calendarday.getYear(); month = calendarday.getMonth() - 1; } // 上个月的最后一天是几号 lastMonthDays = getDateNum(year, month); // 第一个格子展示的是几号 int firstShowDay = lastMonthDays - weekday + 1; // 上月 for (int k = 0; k < weekday; k++) { lastMonthDay = firstShowDay + k; LinearLayout group = getDateView(0, k);
