能否额外支持加一个footView

[zhongcg]

日历(mothView)下方想添加个列表，并跟随日历左右滑动。

可以的，最快下周加好。

大佬牛逼

[sy007]

@zhongcg 你好，calendar-view 1.2.0版本支持了脚布局，请参考simple中SingleHorizontalActivity的写法

[zhongcg]

谢谢大佬，左右已经没问题，还有个问题是如何再实现上下滑动。因为我的footview是一个列表，用来展示当前月的所有节日。 滑动的话不能带上日历一起上下滑动，这个就比较蛋疼了

@zhongcg 你好，这个属于业务上的个性化需求，不在日历库的范围内了。你可以看看CoordinatorLayout+RecyclerView。和NestedScrollView嵌套RecyclerView，这两种方案。后续有空可以考虑demo中加这个场景演示。

[zhongcg]

footview，多行超出屏幕的情况，在滑动到6行的月份时会展示不全。布局就是简单的linearlayout套n个textview， 还有外层嵌套了一个NestedScrollView

[zhongcg]

heightMode = HeightMode.DYNAMIC 的情况就会出现了。。 footerView会被截取掉日历一行的高度

[zhongcg]

还有个问题 不知道为什么设置成我这里heightMode = HeightMode.FIXED 没有效果。

[zhongcg]

footerView不支持动态高度。要是设计上的问题无法支持就只能把列表分离出去，翻页后再更新了，不跟随左右滑动了

[sy007]

NestedScrollView

没有效果指的是什么意思，麻烦把遇到的问题列下。

[zhongcg]

第一个问题 private fun CalendarConfig.getAndFixHeightMode(): HeightMode { if (startCalendarDay.day != startCalendarDay.firstDayOfMonth || endCalendarDay.day != endCalendarDay.lastDayOfMonth) { return HeightMode.DYNAMIC } return heightMode } 这个方法导致设置FIxed无效，不明白这里的逻辑。

第二个问题就是FootView是个列表情况，每个月的底部列表数量不同，滑动后footview高度不足以把列表展示全

[sy007]

第一个问题麻烦发下设置的参数。第二个问题不是日历控件的问题吧，你可以不用日历控件试试NestedScrollView嵌套RecyclerView+LinearLayout(多个TextView)。

        cvSingleCalendarView.apply {

            val startCalendar = Calendar.getInstance().apply {
                set(Calendar.YEAR, 1900)
                set(Calendar.DAY_OF_MONTH, getActualMinimum(Calendar.DAY_OF_MONTH))
                set(Calendar.MONTH, getActualMinimum(Calendar.MONTH))
            }
            val endCalendar = Calendar.getInstance().apply {
                set(Calendar.YEAR, 2100)
                set(Calendar.MONTH, getActualMaximum(Calendar.MONTH))
            }
            //初始化日历展示范围和样式
            val calendarConfig = CalendarConfig(startCalendar, endCalendar).apply {
                //横向滑动
                orientation = RecyclerView.HORIZONTAL
                //ViewPager滚动模式
                scrollMode = ScrollMode.PAGE
                //固定6行高度
                heightMode = HeightMode.FIXED
                //月份视图上展示额外日期
                isDisplayExtraDay = true
            }

[zhongcg]

写到外部是没有问题，把列表写到footview里是觉得一起滑动的效果会好一点，就跟华为日历效果一样，跟随滑动的效果。

[sy007]

        cvSingleCalendarView.apply {

            val startCalendar = Calendar.getInstance().apply {
                set(Calendar.YEAR, 1900)
                set(Calendar.DAY_OF_MONTH, getActualMinimum(Calendar.DAY_OF_MONTH))
                set(Calendar.MONTH, getActualMinimum(Calendar.MONTH))
            }
            val endCalendar = Calendar.getInstance().apply {
                set(Calendar.YEAR, 2100)
                set(Calendar.MONTH, getActualMaximum(Calendar.MONTH))
            }
            //初始化日历展示范围和样式
            val calendarConfig = CalendarConfig(startCalendar, endCalendar).apply {
                //横向滑动
                orientation = RecyclerView.HORIZONTAL
                //ViewPager滚动模式
                scrollMode = ScrollMode.PAGE
                //固定6行高度
                heightMode = HeightMode.FIXED
                //月份视图上展示额外日期
                isDisplayExtraDay = true
            }

要开启FIXED模式，你必须将你的startCalendar的日期设置为该月份的第一天，即1号；将endCalendar的日期设置为该月份的最后一天。不然空间内部会强制改为DYNAMIC模式。你创建的endCalendar，只设置了年和月，日期还是今天的。如果日期设置为该月份的最后一天，可以使用 getActualMaximum(Calendar.DAY_OF_MONTH)
