android实现显示阳历和农历源码

点击打开链接

前些天在网上找阳历转农历的源码找了好久都找不到，但是幸运的是找到了李宁老师《Android/OPhone开发完全讲义》日历的源码，但是可惜的是源码中农历的部分没有了。。

于是在网上找了个Java类的阳历转农历的类Lunar.java。下面开始实现这功能。

Lunar.java类：

 [html] view plaincopyprint?

  167. }
  168. }

 （1）打印一个农历信息在TextView上

 在Grid类的updateMsg方法添加以下代码：
 [html] view plaincopyprint?

    1. Lunar lunar = new Lunar(calendar);
    2.
    3. String lunarStr = "";
    4. lunarStr=lunar.animalsYear()+"年(";
    5. lunarStr +=lunar.cyclical()+"年)";
    6. lunarStr +=lunar.toString();
    7.
    8. tvMsg3.setText(lunarStr);

 Lunar lunar = new Lunar(calendar); String lunarStr = ""; lunarStr=lunar.animalsYear()+"年("; lunarStr +=lunar.cyclical()+"年)"; lunarStr +=lunar.toString(); tvMsg3.setText(lunarStr);
 这样就能实现了，很简单吧！

（2）全部日期都显示农历信息，效果图如下：

 同样在Grid类里的draw(Cavas cavas)方法中

 在for (int i = 0; i < days.length;i++)循环前面添加以下代码：

 [html] view plaincopyprint?

    1. calendar.set(currentYear, currentMonth, currentDay);
    2. SimpleDateFormat abc = new SimpleDateFormat("yyyy年MM月dd日");

 calendar.set(currentYear, currentMonth, currentDay); SimpleDateFormat abc = new SimpleDateFormat("yyyy年MM月dd日");在for (int i = 0; i < days.length;i++)循环里添加以下代码：

 [html] view plaincopyprint?

    1. if (days[i].startsWith("*"))
    2. {
    3. // 下月
    4. if (i > 20)
    5. {
    6. String nowday = currentYear + "年" + (currentMonth+2) + "月" + myText+ "日";
    7. java.util.Calendar currentDay =java.util.Calendar.getInstance();
    8. try {
    9. //定义传入ChineseCalendar参数的格式
   10. currentDay.setTime(abc.parse(nowday));
   11. // System.out.println("currentDay:"+currentDay);
   12. } catch (ParseException e) {
   13. e.printStackTrace();
   14. }
   15. Lunar lunar = new Lunar(currentDay);
   16. String currentDate = lunar.toString();
   17. int startIndex = currentDate.length()-2;
   18. //获取农历月份
   19. String showMonth = currentDate.substring(startIndex-2,startIndex);
   20. //获取农历的日
   21. String showDay = currentDate.substring(startIndex);
   22. //当农历的日为“初一时”，画出该天的月份
   23. //否则画出该天农历的日
   24. if (showDay.equals("初一")) {
   25. canvas.drawText(showMonth, textLeft1, textTop1, paint);
   26. } else {
   27. canvas.drawText(showDay, textLeft1, textTop1, paint);
   28. }
   29. }
   30. // 上月
   31. else
   32. {
   33. String nowday = currentYear + "年" + (currentMonth) + "月" + myText +"日";
   34. java.util.Calendar currentDay =java.util.Calendar.getInstance();
   35. try {
   36. //定义传入ChineseCalendar参数的格式
   37. currentDay.setTime(abc.parse(nowday));
   38. // System.out.println("currentDay:"+currentDay);
   39. } catch (ParseException e) {
   40. e.printStackTrace();
   41. }
   42. Lunar lunar = new Lunar(currentDay);
   43. String currentDate = lunar.toString();
   44. int startIndex = currentDate.length()-2;
   45. //获取农历月份
   46. String showMonth = currentDate.substring(startIndex-2,startIndex);
   47. //获取农历的日
   48. String showDay = currentDate.substring(startIndex);
   49. //当农历的日为“初一时”，画出该天的月份
   50. //否则画出该天农历的日
   51. if (showDay.equals("初一")) {
   52. canvas.drawText(showMonth, textLeft1, textTop1, paint);
   53. } else {
   54. canvas.drawText(showDay, textLeft1, textTop1, paint);
   55. }
   56. }
   57. }else{
   58. String nowday = currentYear + "年" + (currentMonth+1) + "月" + myText+ "日";
   59. java.util.Calendar currentDay =java.util.Calendar.getInstance();
   60. try {
   61. //定义传入ChineseCalendar参数的格式
   62. currentDay.setTime(abc.parse(nowday));
   63. // System.out.println("currentDay:"+currentDay);
   64. } catch (ParseException e) {
   65. e.printStackTrace();
   66. }
   67. Lunar lunar = new Lunar(currentDay);
   68. String currentDate = lunar.toString();
   69. int startIndex = currentDate.length()-2;
   70. //获取农历月份
   71. String showMonth = currentDate.substring(startIndex-2,startIndex);
   72. //获取农历的日
   73. String showDay = currentDate.substring(startIndex);
   74. //当农历的日为“初一时”，画出该天的月份
   75. //否则画出该天农历的日
   76. if (showDay.equals("初一")) {
   77. canvas.drawText(showMonth, textLeft1, textTop1, paint);
   78. } else {
   79. canvas.drawText(showDay, textLeft1, textTop1, paint);
   80. }
   81. }
   82. canvas.drawText(myText, textLeft, textTop, paint);
