将字符串转换为LocalDateTime [英] Convert string into LocalDateTime

问题描述

我有以下字符串:

18/07/2019 16:20

我尝试使用以下代码将此字符串转换为LocalDateTime:

I try to convert this string into LocalDateTime with the following code:

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

java.time.format.DateTimeParseException:文本'18/07/2019 04:30:00' 无法解析:无法从中获取LocalDateTime TemporalAccessor

java.time.format.DateTimeParseException: Text '18/07/2019 04:30:00' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor

我缺少什么?

推荐答案

我认为这将回答您的问题:

I think this will answer your question:

val stringDate = expiration_button.text.toString()
val formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy hh:mm");
val dt = LocalDate.parse(stringDate, formatter);

由于您使用的是12小时制而不是24小时制，因此可能会崩溃.

It's probably crashing because you are using a 12hr Hour, instead of a 24hr pattern.

使用大写字母H将小时更改为24小时应该可以解决此问题:

Changing the hour to 24hr pattern by using a capital H should fix it:

val dateTime = LocalDateTime.parse(stringDate, DateTimeFormatter.ofPattern("dd/MM/yyyy HH:mm"));
