Question

我使用了getRelativeDateTimeString，它显示了最长1周的时间。

如何增加1周以上。
经过一段时间后，它显示正常的日期格式，例如11/14 / 2007，8：20 AM，我想在Nov/14/2007, 8:20 AM或14 Nov 2007, 8:20 AM这样的日期中显示月份名称< / p>

我希望输出为：Nov/14/2007, 8:20 AM，但输出为11/14/2007, 8:20 AM

java.util.Date time = new java.util.Date((long) time1 * 1000);
    int flags = DateUtils.FORMAT_SHOW_DATE | DateUtils.FORMAT_SHOW_YEAR | FORMAT_ABBREV_MONTH;
    CharSequence mdate = DateUtils.getRelativeDateTimeString(context,time.getTime() , DateUtils.SECOND_IN_MILLIS, DateUtils.WEEK_IN_MILLIS, flags);

以下类可用于从时间戳中提取日期：

public static final String DF_hh_mm_a = "hh:mm a";

    }

}

以下代码片段显示了如何使用该类：

 String date = new DateUtils.Builder().setSeconds(timeStamp).setDateFormat(DateUtils.DF_MMMM_dd_yyyy_AT_hh_mm_a).getStringDate();

Answer 2

您可以将其分为两部分：

使用DateFormat f = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.mmm'Z'");
使用getRelativeTimeSpanString

希望有帮助，谢谢
