我设法解析String一个LocalDate对象:

DateTimeFormatter f1=DateTimeFormatter.ofPattern("dd MM yyyy");
LocalDate d=LocalDate.parse("26 08 1984",f1);
System.out.println(d); //prints "1984-08-26"

但我不能这样做LocalTime.这段代码:

DateTimeFormatter f2=DateTimeFormatter.ofPattern("hh mm");
LocalTime t=LocalTime.parse("11 08",f2); //exception here
System.out.println(t);

抛出一个DateTimeParseException:

Exception in thread "main" java.time.format.DateTimeParseException: Text '11 08' could not be parsed: Unable to obtain LocalTime from TemporalAccessor: {MinuteOfHour=8, HourOfAmPm=11},ISO of type java.time.format.Parsed

LocalDateTime.parse("2017-02-02 08:59:12", DateTimeFormatter.ofPattern("yyyy-MM-dd hh:mm:ss"));

它打印错误:

java.time.format.DateTimeParseException: Text '2017-02-02 08:59:12' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor: {MinuteOfHour=59, NanoOfSecond=0, SecondOfMinute=12, MicroOfSecond=0, MilliOfSecond=0, HourOfAmPm=8},ISO resolved to 2017-02-02 of type java.time.format.Parsed

Accoeding消息看起来像所有值解析正确,但无论如何我看到错误.

如何让它工作？

我有以下字符串：

18/07/2019 16:20

我尝试LocalDateTime使用以下代码将此字符串转换为：

val stringDate = expiration_button.text.toString()
val date = LocalDateTime.parse(stringDate, DateTimeFormatter.ofPattern("dd/MM/yyyy hh:mm")).toString()

java.time.format.DateTimeParseException：无法解析文本“18/07/2019 04:30:00”：无法从 TemporalAccessor 获取 LocalDateTime

我缺少什么？
