android - Android DOM 解析 - 转换 pubDate 标签

Question

我使用 DOM Parser 来解析这个 XML 提要：http ://loc.grupolusofona.pt/index.php/?format=feed

它工作正常，解析了我需要的所有字段，但我想将从标签 pubDate 获得的结果从“Wed，2012 年 10 月 31 日 17:12:42 +0000”转换为“2 天前，17:12”或其他东西像这样。

我该怎么做 ？

提前致谢。

这是您需要的代码：

String dateString = "Wed, 31 Oct 2012 12:12:42 +0100";
SimpleDateFormat sdf = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss z", Locale.US);
Date date = null;
try {
    date = sdf.parse(dateString);
    String timeOfDay = new SimpleDateFormat("HH:mm").format(date);
    java.sql.Timestamp timeStampDate = new Timestamp(date.getTime());
    java.sql.Timestamp timeStampNow = new Timestamp((new java.util.Date()).getTime());

    long secondDiff = timeStampNow.getTime() / 1000 - timeStampDate.getTime() / 1000;
    int minuteDiff = (int) (secondDiff / 60);
    int hourDiff = (int) (secondDiff / 3600);
    int dayDiff = daysBetween(date, new Date()) - 1;
    if (dayDiff > 0) {
        System.out.println("Posted " + dayDiff + " days ago @ " + timeOfDay);
    } else if (hourDiff > 0) {
        System.out.println("Posted " + hourDiff + " hour(s) ago @ " + timeOfDay);
    } else if (minuteDiff > 0) {
        System.out.println("Posted " + minuteDiff + " minute(s) ago @ " + timeOfDay);
    } else if (secondDiff > 0) {
        System.out.println("Posted " + secondDiff + " second(s) ago @ " + timeOfDay);
    }
} catch (ParseException e) {
    e.printStackTrace();
}

天数：

public static int daysBetween(Date startDate, Date endDate) {
    int daysBetween = 0;
    while (startDate.before(endDate)) {
        startDate.setTime(startDate.getTime() + 86400000);
        daysBetween++;
    }
    return daysBetween;
}

输出： 2天前@ 12:12发布
