Android日期+时间选择器

参考链接：https://juejin.cn/post/6917909994985750535

可自定义修改的内容总结如下：

1：可以展示或隐藏年月日时分秒的文字
2：修改文字颜色
3：修改字号
4：修改全部标签文字，比如显示成：2023Y 07M 14D 15H 21M 47S
5：可以只展示年月、年月日、年月日时分等
6：可以使用1-6个Numpicker自定义UI，摆放位置自己设置
7：可以设置最大时间、最小时间
8：可以设置分割线颜色
9：可以设置整体文字加粗或者只有选中的文字加粗

修改字体大小、颜色等视觉效果建议在xml中进行

自定义工具类

object DateTimeHelper {
    interface OnSelectDateTimeListener
    {
        fun onSelect(millisecond : Long)
    }

    class Builder(mDateTimePicker : DateTimePicker) {

工具类用法

 DateTimeHelper.Builder(binding.dateTimePicker).
            showYear().
            showMonth().
            showDay().
            setYearText("").
            setMaxTime("2025-01-01 00:00:00").
            setOnDateTimeChangedListener(object : DateTimeHelper.OnSelectDateTimeListener{
                override fun onSelect(millisecond: Long) {
                    selectTime = millisecond
                }
        }).build()
