前些天在網(wǎng)上找陽(yáng)歷轉(zhuǎn)農(nóng)歷的源碼找了好久都找不到，但是幸運(yùn)的是找到了李寧老師《Android/OPhone開發(fā)完全講義》日歷的源碼

，但是可惜的是源碼中農(nóng)歷的部分沒有了。。

于是在網(wǎng)上找了個(gè)Java類的陽(yáng)歷轉(zhuǎn)農(nóng)歷的類Lunar.java。

下面開始實(shí)現(xiàn)這功能。

(1)打印一個(gè)農(nóng)歷信息在TextView上

在Grid類的updateMsg方法添加以下代碼：

Lunar lunar = new Lunar(calendar);

String lunarStr = "";

lunarStr=lunar.animalsYear()+"年(";

lunarStr +=lunar.cyclical()+"年)";

lunarStr +=lunar.toString();

tvMsg3.setText(lunarStr);這樣就能實(shí)現(xiàn)了，很簡(jiǎn)單吧！

(2)全部日期都顯示農(nóng)歷信息，效果圖如下：

同樣在Grid類里的draw(Cavas cavas)方法中

在for (int i = 0; i < days.length;i++)循環(huán)前面添加以下代碼：

calendar.set(currentYear, currentMonth, currentDay);

SimpleDateFormat abc = new SimpleDateFormat("yyyy年MM月dd日");在for (int i = 0; i < days.length;i++)循環(huán)里添加以下代碼：

if (days[i].startsWith("*"))

{

// 下月

if (i > 20)

{

String nowday = currentYear + "年" + (currentMonth+2) + "月" + myText+ "日";

java.util.Calendar currentDay =java.util.Calendar.getInstance();

try {

//定義傳入ChineseCalendar參數(shù)的格式

currentDay.setTime(abc.parse(nowday));

// System.out.println("currentDay:"+currentDay);

} catch (ParseException e) {

e.printStackTrace();

}

Lunar lunar = new Lunar(currentDay);

String currentDate = lunar.toString();

int startIndex = currentDate.length()-2;

//獲取農(nóng)歷月份

String showMonth = currentDate.substring(startIndex-2,startIndex);

//獲取農(nóng)歷的日

String showDay = currentDate.substring(startIndex);

//當(dāng)農(nóng)歷的日為“初一時(shí)”，畫出該天的月份

//否則畫出該天農(nóng)歷的日

if (showDay.equals("初一")) {

canvas.drawText(showMonth, textLeft1, textTop1, paint);

} else {

canvas.drawText(showDay, textLeft1, textTop1, paint);

}

}

// 上月

else

{

String nowday = currentYear + "年" + (currentMonth) + "月" + myText +"日";

java.util.Calendar currentDay =java.util.Calendar.getInstance();
