我用Excel模擬出一個日歷，不同的顏色區域（當前日歷紅色除外），把整個日歷作為分成三塊，如果按照BlackBerry程序的方式，分為三個布局管理器，最上面是一個HorizontalFieldManager，日歷的周那個區域也是HorizontalFieldManager，日期區域每行看成一個HorizontalFieldManager，整體看成一個VerticalFieldManager，而整個日歷可看成一個VerticalFieldManager去規范里面的布局。這樣一個完整的日歷就出來了。具體實現如下：
package org.bulktree.calender;
import java.util.Calendar;
import net.rim.device.api.ui.Field;
import net.rim.device.api.ui.FocusChangeListener;
import net.rim.device.api.ui.Font;
import net.rim.device.api.ui.Manager;
import net.rim.device.api.ui.component.LabelField;
import net.rim.device.api.ui.container.HorizontalFieldManager;
import net.rim.device.api.ui.container.VerticalFieldManager;
public class CalenderLayout {
private static String[] wks = {"日", "一", "二", "三", "四", "五", "六"};
private LabelField ax = null;
public Manager calLayout() {
Manager calender = new VerticalFieldManager();
//日歷頭
Manager calHeader = new HorizontalFieldManager();
Calendar cale = Calendar.getInstance();
ChineseCalendar chin = new ChineseCalendar(cale);
String calHeaderString = "陰歷:" + CalendarUtil.getCurrentYear() + "年 " + chin.getChineseCalendarMonth() + "月 "+ chin.getChinaDayString() + "日{" + chin.getCyclical() + "-" + chin.getAnimalsYear() + "年}";
ax = new LabelField(calHeaderString, LabelField.HCENTER);
setFont(ax, 13, 1);
calHeader.add(ax);
LabelField ay = new LabelField(" 陽歷：" + CalendarUtil.getCurrentMonth() + "月");
setFont(ay, 13, 1);
calHeader.add(ay);
calender.add(calHeader);
//星期頭
Manager weakHeader = new HorizontalFieldManager();
CalenderField whf = null;
for (int i = 0; i < 7; i++) {
whf = new CalenderField(wks[i], CalenderField.RECTANGLE, CalenderField.NON_FOCUSABLE, 1);
setFont(whf, 15, 1);
weakHeader.add(whf);
}
calender.add(weakHeader);
//日歷體
int a = CalendarUtil.getWeekCurrntMonthFirstDay();
// int a = CalendarUtil.getWeekMonthFirstDay(2011, 1);
int b = CalendarUtil.getCurrentDaysOfMonth();
// int b = CalendarUtil.getDaysOfMonth(2011, 1);
Manager calBody = new HorizontalFieldManager();
calBody.setBorder(1, 1, 1, 1);
for (int i = 0; i < a; i++) {
calBody.add(new CalenderField("", CalenderField.RECTANGLE, CalenderField.NON_FOCUSABLE, 1));
}
CalenderField yac = null;
CalenderField yc = null;
for (int i = 1; i <= b; i++) {
Manager cellManger = new VerticalFieldManager();
yac = new CalenderField(i + "", CalenderField.HCENTER, CalenderField.FOCUSABLE, 1);
setFont(yac, 15, 0);
cellManger.add(yac);
Calendar cx = Calendar.getInstance();
cx.set(Calendar.DATE, i);
final ChineseCalendar chines = new ChineseCalendar(cx);
yc = new CalenderField(chines.getChinaDayString(), CalenderField.HCENTER, CalenderField.NON_FOCUSABLE, 1);
setFont(yc, 10, 0);
yac.setFocusListener(new FocusChangeListener() {
public void focusChanged(Field field, int eventType) {
String text = "陰歷:" + chines.getChineseCalenderYear() + "年 " + chines.getChineseCalendarMonth() + "月 "+ chines.getChinaDayString() + "日{" + chines.getCyclical() + "-" + chines.getAnimalsYear() + "年}";
updateCalendarHeader(text);
}
});
if (Calendar.getInstance().get(Calendar.DATE) == i) {
setFont(yac, 15, 1);
setFont(yc, 10, 1);
}
cellManger.add(yc);
calBody.add(cellManger);
if ((i + a) % 7 ==0) {
calender.add(calBody);
calBody = new HorizontalFieldManager();
}
}
calender.add(calBody);
return calender;
}
/**
* 設置字體風格
* @param obj
* @param size
* @param isBlod 是否加粗， 1加粗， 0 正常
*/
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農歷工具類，CalenderField自定義的UI（上篇專門說明過）。現貼出代碼如下：
package org.bulktree.calender;
import java.util.Calendar;
public class ChineseCalendar {
private int year;
private int month;
private int day;
private boolean leap;
final static String chineseNumber[] = {"一", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "十二"};
final static long[] lunarInfo = new long[]
