开发中碰到个需求，需要在一个空间中选择完成开始和结束时间。实现的过程走的是程序员开发的老路子，找到*后自己改吧改吧就成了。
当时做的时候有几个需求：1.当天为最大的结束日期，2.最大选择范围1年，3.开始时间和结束时间可以为同一天。如有其他需求实现，可以参考代码改进一下。先上效果图：
视频点击后的虚影是屏幕录制的原因。实现步骤：(如有缺失什么资源，请告知。开始时间和结束时间显示自己布局内添加就可以)
1.自定义控件属性
<declare-styleable name="mycalendar"> <attr name="dateformat" format="string"></attr> <attr name="titlesize" format="dimension"></attr> <attr name="titlecolor" format="color"></attr> <attr name="goicon" format="reference"></attr> <attr name="preicon" format="reference"></attr> <attr name="dayinmonthcolor" format="color"></attr> <attr name="dayoutmonthcolor" format="color"></attr> <attr name="todaycolor" format="color"></attr> <attr name="todayemptycirclecolor" format="color"></attr> <attr name="todayfillcirclecolor" format="color"></attr> <attr name="calendarbackground" format="color|reference"></attr> </declare-styleable>
2.自定义控件代码
