关键修改

原代码做的非常的简洁，非常适合咱们通过自定义来获取自己的效果，比如我们想做一个展示签到信息的日历，只需要在原加载日历的代码后加入我们的签到信息即可
CalendarViewFragment：

/**
     * 加载签到数据
     * @param mListDataCalendar
     */
    private void initSigninData(List<CalendarDate> mListDataCalendar) {
        
        //在加载日历数据之前加载签到数据（或者是先加载日历数据然后再加载签到数据，加载完签到数据之后刷新数据即可）
        ArrayList<String> signinDatas = new ArrayList<>();
        Random random = new Random();
        //生成签到数据(这里是根据接口获取的)
        for(int i = 0 ; i < 10 ; i ++){
            signinDatas.add(mYear +"-" + mMonth + "-" + random.nextInt(28));
        }

        //将签到数据加到日历中
        for (CalendarDate calendarDate : mListDataCalendar) {
            if(calendarDate != null && calendarDate.getSolar() != null){
                for (String signinData : signinDatas) {
                    if(!TextUtils.isEmpty(signinData)
                            && signinData.equals(calendarDate.getSolar().solarYear + "-" + calendarDate.getSolar().solarMonth + "-" + calendarDate.getSolar().solarDay)){
                        calendarDate.setSignin(true);
                        break;
                    }
                }
            }
        }
