我用Excel模擬出一個(gè)日歷，不同的顏色區(qū)域（當(dāng)前日歷紅色除外），把整個(gè)日歷作為分成三塊，如果按照BlackBerry程序的方式，分為三個(gè)布局管理器，最上面是一個(gè)HorizontalFieldManager，日歷的周那個(gè)區(qū)域也是HorizontalFieldManager，日期區(qū)域每行看成一個(gè)HorizontalFieldManager，整體看成一個(gè)VerticalFieldManager，而整個(gè)日歷可看成一個(gè)VerticalFieldManager去規(guī)范里面的布局。這樣一個(gè)完整的日歷就出來了。具體實(shí)現(xiàn)如下：

calBody.setBorder(1, 1, 1, 1);

return calender;
}
/**

*/
private void setFont(Field obj, int size, int isBlod) {
int fontStyle = isBlod == 1 ? Font.BOLD : Font.PLAIN;
obj.setFont(Font.getDefault().derive(fontStyle, size));
}
private void updateCalendarHeader(String text) {
ax.setText(text);
}
}
這里面用到CalendarUtil工具類，ChineseCalendar農(nóng)歷工具類，CalenderField自定義的UI（上篇專門說明過）?，F(xiàn)貼出代碼如下：

private int month;

final static String chineseNumber[] = {"一", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "十二"};
final static long[] lunarInfo = new long[]
