只有dialog 显示，然后在 日历 中日期的计算。
使用了一个wheelview 第三方的view ，就一个java 文件就搞定了，其它的代码都是自己写的。
这样三个java 文件就搞定了，减少了第三方的使用。
使用。
var dialog = SelectBirthdayDialog(this)
dialog.setData(birthdays, monthDatas, dayDatas)
dialog.onSelectBirthdayLinsener = object : SelectBirthdayDialog.OnSelectBirthdayLinsener {
override fun selectBirthdayLinsener(
birthdayData: SelectBirthdayDialog.BirthDayBean?,
monthData: SelectBirthdayDialog.BirthDayBean?,
dayData: SelectBirthdayDialog.BirthDayBean?) {
birthdays = birthdayData
monthDatas = monthData
dayDatas = dayData
tvBirthday.text = "" + birthdayData?.value + "-" + monthData?.value + "-" + dayData?.value
dialog.dismiss()
}
}
dialog.show()
传入上次选择的。如果上次没有就显示 进入的日期。 日期选择是一年的任意日期。
想要修改，直接修改结束时间就可以了..
其它内容
SelectBirthdayDialog.kt
style.xml
dialog_select_region.xml
WheelView.java
IWheelEntity.java
其它没有了。。。。
java 文件是第三方的 。
style.xml
