一、概述
MaterialCalendarView是一个开源项目。功能强大支持多选、单选、标注等。
二、问题
1、其继承自ViewGroup，故与CalendarView半毛钱关系都没有，完全是一个新的类
2、其子类CalendarDay是经过调整的
CalendarDay date = new CalendarDay();
......
Log.e(LOG_TAG, "Date选中日期：" + date.getDate().getYear() + "-" + date.getDate().getMonth() + "-" + date.getDate().getDay());
Log.e(LOG_TAG, "Calendar选中日期：" + date.getCalendar().get(Calendar.YEAR) + "-" + (date.getCalendar().get(Calendar.MONTH) + 1) + "-" + date.getCalendar().get(Calendar.DAY_OF_MONTH));
得到的结果为
Date选中日期：116-3-6
Calendar选中日期：2016-4-30
即：
CalendarDay.getDate().getYear()得到的年份 = 真实年份 - 1900
CalendarDay.getDate().getMonth()得到的月份 = 真实年份 - 1
CalendarDay.getDate().getDay()得到的日 = 星期数 - 1
3、关于DayViewDecorator类
此类为抽象类，定义如下
/**
* Decorate Day views with drawables and text manipulation
*/
public interface DayViewDecorator {
/**
* Determine if a specific day should be decorated
*
* @param day {@linkplain CalendarDay} to possibly decorate
* @return true if this decorator should be applied to the provided day
*/
boolean shouldDecorate(CalendarDay day);
/**
* Set decoration options onto a facade to be applied to all relevant days
*
* @param view View to decorate
*/
void decorate(DayViewFacade view);
}
实际使用时，只需实现上述两个方法即可，例如
public class EventDecorator implements DayViewDecorator {
private final int color;
private final HashSet<CalendarDay> dates;
public EventDecorator(int color, Collection<CalendarDay> dates) {
this.color = color;
this.dates = new HashSet<>(dates);
}
@Override
public boolean shouldDecorate(CalendarDay day) {
return dates.contains(day);
}
@Override
public void decorate(DayViewFacade view) {
view.addSpan(new DotSpan(5, color));
}
}
