最近公司项目中有一个按日期查看信息的功能，楼主本想用之前用的wheelView将就使用的，不过产品经理有个新要求，就是点击按钮弹出的日期选择对话框必须显示农历节假日，周几什么的。这可就难为人了，倘若使用之前的滚动时间选择器，无疑是难以实现的，楼主辗转反侧，冥思苦想，却不得正果。
好吧，去网上下了几个OA系统一用就有了idea，突然想到手机自带的日历~~，oh，year，日历就有这功能，瞧瞧，我靠，这个东西，咋做。
仔细一瞧，似乎用GridView可以实现，额，二话不说就开干。折腾了半天都没弄好，而且界面贼丑，并且特别是国历和公历上面如何一一对应呢？
遇上楼主上google科普了一番，发现网上自定义日历不少，可是没有楼主想要的，好不容易找到一个功能齐全，可惜代码调了半天也用不起，好吧，只能一步一个脚印慢慢做。
终于功夫不负有心人，最终楼主还是弄出来一个雏形。
额，对，基本实现了日历功能，并能自动定位当前日期以及本月和非本月日期显示的不同，而且支持左右滑动哦~~
额，有图有真相。
最后，楼主把Demo分离了出来，供大家分享参阅。
view包下几个东西。
