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?   1. public class Lunar {     2. private int year;     3. private int month;     4. private int day;     5. private boolean leap;     6. final static String chineseNumber[] = {"一", "二", "三", "四", "五","六", "七", "八", "九", "十", "十一", "十二"};     7. static SimpleDateFormat chineseDateFormat = newSimpleDateFormat("yyyy年MM月dd日");     8. final static long[] lunarInfo = new long[]     9. {0x04bd8, 0x04ae0, 0x0a570, 0x054d5, 0x0d260, 0x0d950, 0x16554,0x056a0, 0x09ad0, 0x055d2,    10. 0x04ae0, 0x0a5b6, 0x0a4d0, 0x0d250, 0x1d255, 0x0b540, 0x0d6a0,0x0ada2, 0x095b0, 0x14977,    11. 0x04970, 0x0a4b0, 0x0b4b5, 0x06a50, 0x06d40, 0x1ab54, 0x02b60,0x09570, 0x052f2, 0x04970,    12. 0x06566, 0x0d4a0, 0x0ea50, 0x06e95, 0x05ad0, 0x02b60, 0x186e3,0x092e0, 0x1c8d7, 0x0c950,    13. 0x0d4a0, 0x1d8a6, 0x0b550, 0x056a0, 0x1a5b4, 0x025d0, 0x092d0,0x0d2b2, 0x0a950, 0x0b557,    14. 0x06ca0, 0x0b550, 0x15355, 0x04da0, 0x0a5d0, 0x14573, 0x052d0,0x0a9a8, 0x0e950, 0x06aa0,    15. 0x0aea6, 0x0ab50, 0x04b60, 0x0aae4, 0x0a570, 0x05260, 0x0f263,0x0d950, 0x05b57, 0x056a0,    16. 0x096d0, 0x04dd5, 0x04ad0, 0x0a4d0, 0x0d4d4, 0x0d250, 0x0d558,0x0b540, 0x0b5a0, 0x195a6,    17. 0x095b0, 0x049b0, 0x0a974, 0x0a4b0, 0x0b27a, 0x06a50, 0x06d40,0x0af46, 0x0ab60, 0x09570,    18. 0x04af5, 0x04970, 0x064b0, 0x074a3, 0x0ea50, 0x06b58, 0x055c0,0x0ab60, 0x096d5, 0x092e0,    19. 0x0c960, 0x0d954, 0x0d4a0, 0x0da50, 0x07552, 0x056a0, 0x0abb7,0x025d0, 0x092d0, 0x0cab5,    20. 0x0a950, 0x0b4a0, 0x0baa4, 0x0ad50, 0x055d9, 0x04ba0, 0x0a5b0,0x15176, 0x052b0, 0x0a930,    21. 0x07954, 0x06aa0, 0x0ad50, 0x05b52, 0x04b60, 0x0a6e6, 0x0a4e0,0x0d260, 0x0ea65, 0x0d530,    22. 0x05aa0, 0x076a3, 0x096d0, 0x04bd7, 0x04ad0, 0x0a4d0, 0x1d0b6,0x0d250, 0x0d520, 0x0dd45,    23. 0x0b5a0, 0x056d0, 0x055b2, 0x049b0, 0x0a577, 0x0a4b0, 0x0aa50,0x1b255, 0x06d20, 0x0ada0};    24.     25. //====== 传回农历 y年的总天数    26. final private static int yearDays(int y) {    27. int i, sum = 348;    28. for (i = 0x8000; i > 0x8; i>>= 1) {    29. if ((lunarInfo[y - 1900] & i) != 0) sum += 1;    30. }    31. return (sum + leapDays(y));    32. }    33.     34. //====== 传回农历 y年闰月的天数    35. final private static int leapDays(int y) {    36. if (leapMonth(y) != 0) {    37. if ((lunarInfo[y - 1900] & 0x10000) != 0)    38. return 30;    39. else    40. return 29;    41. } else    42. return 0;    43. }    44.     45. //====== 传回农历 y年闰哪个月 1-12 , 没闰传回 0    46. final private static int leapMonth(int y) {    47. return (int) (lunarInfo[y - 1900] & 0xf);    48. }    49.     50. //====== 传回农历 y年m月的总天数    51. final private static int monthDays(int y, int m) {    52. if ((lunarInfo[y - 1900] & (0x10000>> m)) == 0)    53. return 29;    54. else    55. return 30;    56. }    57.     58. //====== 传回农历 y年的生肖    59. final public String animalsYear() {    60. final String[] Animals = new String[]{"鼠", "牛", "虎", "兔", "龙", "蛇","马", "羊", "猴", "鸡", "狗", "猪"};    61. return Animals[(year - 4) % 12];    62. }    63.     64. //====== 传入 月日的offset 传回干支, 0=甲子    65. final private static String cyclicalm(int num) {    66. final String[] Gan = new String[]{"甲", "乙", "丙", "丁", "戊", "己","庚", "辛", "壬", "癸"};    67. final String[] Zhi = new String[]{"子", "丑", "寅", "卯", "辰", "巳","午", "未", "申", "酉", "戌", "亥"};    68. return (Gan[num % 10] + Zhi[num % 12]);    69. }    70.     71. //====== 传入 offset 传回干支, 0=甲子    72. final public String cyclical() {    73. int num = year - 1900 + 36;    74. return (cyclicalm(num));    75. }    76. public String getLunarMonthString() {    77. // TODO Auto-generated method stub    78. return null;    79. }    80.     81. public Lunar(Calendar cal) {    82. @SuppressWarnings("unused") int yearCyl, monCyl, dayCyl;    83. int leapMonth = 0;    84.

（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.

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);
