getRelativeDateTimeString与星期几？

Question

是否有任何选项可以在一周中获得getRelativeDateTimeString。也就是说，如果日期是7天内其显示为星期一，上午07点14分，而不是3天前，上午07点14

DateUtils.getRelativeDateTimeString(context, 
      datewithTime.getTime(), DateUtils.SECOND_IN_MILLIS, DateUtils.WEEK_IN_MILLIS, 0)

嗨，你可以使用这样，

public class TimeUtils extends android.text.format.DateUtils { 

    private static boolean isWithinWeek(final long millis) { 
     return System.currentTimeMillis() - millis <= (WEEK_IN_MILLIS - DAY_IN_MILLIS); 
    } 

    private static boolean isWithinYear(final long millis) { 
     return System.currentTimeMillis() - millis <= YEAR_IN_MILLIS; 
    } 

    public static String getRelativeTimeSpanString(final Context c, final long millis) { 
     final String dateString; 
     if (isToday(millis)) { 
      dateString = formatDate(millis, "h:mm:ss a"); 
      // dateString = DateUtils.formatDateTime(c, millis, DateUtils.FORMAT_SHOW_TIME 
      // | DateUtils.FORMAT_ABBREV_TIME); 
     } else if (isWithinWeek(millis)) { 
      dateString = DateUtils.formatDateTime(c, millis, 
        DateUtils.FORMAT_SHOW_WEEKDAY | DateUtils.FORMAT_ABBREV_WEEKDAY); 
     } else if (isWithinYear(millis)) { 
      dateString = DateUtils.formatDateTime(c, millis, 
        DateUtils.FORMAT_SHOW_DATE | DateUtils.FORMAT_NO_YEAR 
          | DateUtils.FORMAT_ABBREV_ALL); 
     } else { 
      dateString = DateUtils.formatDateTime(c, millis, 
        DateUtils.FORMAT_NUMERIC_DATE); 
     } 
     return dateString; 
    } 

    /** 
    * To format the Current time 
    * 
    * @param dateFormat 
    * @return formated current time value. 
    */ 
    public static String formatCurrentTime(String dateFormat) { 
     return formatDate(System.currentTimeMillis(), dateFormat); 
    } 

    /** 
    * To format the time in a readable given format. 
    * 
    * @param milliSeconds - Time in milliseconds 
    * @param dateFormat - Format date 
    * @return formated time value. 
    */ 
    public static String formatDate(long milliSeconds, String dateFormat) { 
     if (dateFormat == null) { 
      dateFormat = "hh:mm:ss.SSS"; 
     } 
     SimpleDateFormat formatter = new SimpleDateFormat(dateFormat); 

     /** 
     * we are creating the calendar instance and setting the time value. 
     */ 
     Calendar calendar = Calendar.getInstance(); 
     calendar.setTimeInMillis(milliSeconds); 

     return formatter.format(calendar.getTime()); 
    } 
}
