项目中时间处理----今天：时分（10:15），昨天/前天：（昨天/前天），除此之外的本周（星期几），再往前年.月.日（2017.06.15）

导入：

import org.joda.time.LocalDateTime;

//格式化时间
    private String formatTime(LocalDateTime now, Date beginDate) {
        LocalDateTime beginDt = new LocalDateTime(beginDate.getTime());
        if (now.getYear() == beginDt.getYear() && now.getMonthOfYear() == beginDt.getMonthOfYear()
                && now.getDayOfMonth() == beginDt.getDayOfMonth()) {
            return beginDt.toString("HH:mm");
        }
        if (now.getYear() == beginDt.getYear() && now.getMonthOfYear() == beginDt.getMonthOfYear()
                && now.getDayOfMonth() == beginDt.getDayOfMonth() + 1) {
            return "昨天";
        }
        if (now.getYear() == beginDt.getYear() && now.getMonthOfYear() == beginDt.getMonthOfYear()
                && now.getDayOfMonth() == beginDt.getDayOfMonth() + 2) {
            return "前天";
        }
        if (now.getYear() == beginDt.getYear() && now.getMonthOfYear() == beginDt.getMonthOfYear()
                && now.getWeekOfWeekyear() == beginDt.getWeekOfWeekyear()) {
            int i = beginDt.getDayOfWeek();
            if (i == 1) {
                return "星期一";
            } else if (i == 2) {
                return "星期二";
            } else if (i == 3) {
                return "星期三";
            } else if (i == 4) {
                return "星期四";
            } else if (i == 5) {
                return "星期五";
            } else if (i == 6) {
                return "星期六";
            } else {
                return "星期天";
            }
        }
        return beginDt.toString("yyyy.MM.dd");
    }

调用的时候这样调用：

LocalDateTime now = LocalDateTime.now();
            for (ShortMessage s : messageList) {
                Date beginDate = s.getBeginDate();
                s.setStartDate(formatTime(now, beginDate));
            }
