比较字符串日期和今天的日期 [英] Comparing string date with today's date

问题描述

所以我有一个字符串 2014-06-30 15:27，如果今天是今天，它应该只返回 15:27，否则返回 30/06/2014。我已经尝试了simpleDateFormat.parse，但是效果不佳。

So I have a string which is "2014-06-30 15:27" and if it is today's date it should only return "15:27" else "30/06/2014". I've already tried simpleDateFormat.parse but it didn't work very well.

holder.data.setText(mensagem.getDate());

推荐答案

    final String stringDate = "2014-07-17 23:59";

    SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm");
    Date date = inputFormat.parse(stringDate);

    Calendar calendarDate = Calendar.getInstance();
    calendarDate.setTime(date);

    Calendar midnight = Calendar.getInstance();
    midnight.set(Calendar.HOUR_OF_DAY, 0);
    midnight.set(Calendar.MINUTE, 0);
    midnight.set(Calendar.SECOND, 0);
    midnight.set(Calendar.MILLISECOND, 0);

    if (calendarDate.compareTo(midnight) >= 0)
    {
        SimpleDateFormat timeFormat = new SimpleDateFormat("HH:mm");
        System.out.println(timeFormat.format(date));
    }
    else
    {
        SimpleDateFormat dateTimeForm = new SimpleDateFormat("dd/MM/yyyy HH:mm");
        System.out.println(dateTimeForm.format(date));
    }
