如何将UTC偏移量dateformat字符串解析为以|分隔的结果日期象征 [英] How to parse a UTC offset dateformat string into the resulting date separated by | symbol

问题描述

我在尝试解析"2019-12-25T17:00:00-05:00"时有一个非常特殊的问题 这样它应该给我结果DEC 12 | Thursday | 5:00pm

I have a very peculiar question where I am trying to parse "2019-12-25T17:00:00-05:00" such that it should give me the result DEC 12 | Thursday | 5:00pm

我通过使用DateTimeFormatter和LocalDate

DateTimeFormatter inputFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ssz", Locale.US);
                DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("MM d | E | hh:mm a", Locale.US);
                LocalDate date = LocalDate.parse("2019-12-25T17:00:00-05:00", inputFormatter);
                String formattedDate = outputFormatter.format(date);
                contentTextView.setText(formattedDate);

但它因DateTimeParseException: Text '2019-12-25T17:00:00-05:00' could not be parsed at index 19

有人知道它为什么崩溃以及我的输出是否可以提供预期的结果? 谢谢！

Any idea why it's crashing and if my output will render the expected result? Thanks!

推荐答案

您的字符串2019-12-25T17:00:00-05:00表示UTC时区，其偏移量 UTC偏移量，因此请使用OffsetDateTime来解析该字符串

Your String 2019-12-25T17:00:00-05:00 represents UTC timezone with offset UTC offset, so use OffsetDateTime for parsing that string

OffsetDateTime odt = OffsetDateTime.parse("2019-12-25T17:00:00-05:00");

System.out.println(odt.format(DateTimeFormatter.ofPattern("MMM d | E | hh:mm a", Locale.US)));

如果要设置特定的时区，可以使用atZoneSameInstant传递ZoneId作为eaxmple

If you want to set particular time zone you can use atZoneSameInstant to pass ZoneId for eaxmple

ZoneId zone = ZoneId.of("America/Chicago");
ZonedDateTime zdt = odt.atZoneSameInstant(zone);
