下面是我两年前写的一个方法,_UID为空就行。类你自己建

/**
* 日历的生成代码
* @param _year
* @param _month
* @param _uid
* @return
* @throws ParseException
*/
public String getCalendar(String _year,String _month,String _uid) throws ParseException{

/* 说明:
* date = df.parse("2006-11-01");
* 只需要修改上面的日期
*/
String rtn = null;
Date() date = null;
int day = 0;
int days = 0;

Date()Format df = new SimpleDate()Format("yyyy-MM-dd");
Calendar c = Calendar.getInstance();

date = df.parse(_year+"-"+_month+"-01");
c.setTime(date);

day =date.getDay();
Date dt = new Date();
days = c.getActualMaximum(Calendar.DAY_OF_MONTH);

rtn = "\n";

rtn = rtn + "\t\n";
rtn = rtn + "\t\t\n";
rtn = rtn + "\t\t\n";
rtn = rtn + "\t\t\n";
rtn = rtn + "\t\t\n";

int i=0;
for(;iif(i%7 ==0 && i != 0){
rtn = rtn + "\t\n";
rtn = rtn + "\t\n";
}
rtn = rtn + "\t\t\n";
}

for(i=day;i<(days+day);i++){
if(i%7 ==0){
rtn = rtn + "\t\n";
rtn = rtn + "\t\n";

rtn = rtn + "\t\t\n";

rtn = rtn + "\t\n";
rtn = rtn + "\t\n";
}
rtn = rtn + "\t\t\n";
}
rtn = rtn + "\t\n";
rtn = rtn + "
星期日星期一星期二星期三星期四星期五星期六

rtn = rtn + " ";
rtn = rtn + "

if(df.format(dt).equals(_year+"-"+_month+"-"+((i-day+1)<10?"0"+String.valueOf(i-day+1):String.valueOf(i-day+1)))){
