android農歷轉公歷（公農歷相互裝換）時間選者器

最近公司在做一個時間選者器，涉及到日歷裝換，單個選擇器到是沒什麼，但是又有農歷裝換就比較頭疼了，下面分享一個日歷轉換器的代碼，公歷轉農歷的網上很多了，但是農歷轉公歷德就比較少了，

直接上代碼：

package com.openbook.mars.utils;


/**
* 該類主要做農歷和公歷的互轉 支持1900到2050年
* System.out.println(日歷測試);
System.out.println(ChineseCalendarTwo.sCalendarLundarToSolar(2015, 9, 2)); 農轉工
System.out.println(ChineseCalendarTwo.sCalendarSolarToLundar(2015, 9, 2)); 工轉農
