如何在日期和时间中分割完整日期格式？ [英] How to split the full date format in date and time?

问题描述

我有很多必须解析的示例所示格式的字符串。我正在尝试确定今天是哪些弦乐。

I have a lot of Strings in the format shown my example that I have to parse. I'm trying to determine which of the Strings are today.

我的问题是，时间快到了，我只需要比较一下日期即可。

My problem is, that the time is almost there and I just need to compare that date.

下一步我想检查时间是否在带有.after和.before的两个时间戳 HH：mm：ss之间，但是有一个问题，日期快到了。

Next I want to check if time is between two timestamps "HH:mm:ss" with .after and .before, but there is the problem, that the date is almost there.

如何在日期和时间上拆分解析后的格式，以自己的方式处理每种格式？

How do I split that parsed format in date and time to handle each in its own way?

如果相关，我正在Android Studio中工作。

I'm working in Android Studio, if that's relevant.

String dtStart = "2016-05-23 07:24:59";
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

try {

     if (new Date().equals(format.parse(dtStart)) ) System.out.println("true");
     else System.out.println("false");

     list.add(new LatLng(lat, lng));

} catch (java.text.ParseException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
}

推荐答案

java.time

使用 java.time 类。

许多功能已反向移植到Java 6& ThreeTen-Backport 中的第7部分，并进一步在 ThreeTen-ABP 。

Much of the functionality has been back-ported to Java 6 & 7 in ThreeTen-Backport, and further adapted to Android in ThreeTen-ABP.

String dateToParse = "2016-05-23 07:24:59";
LocalDateTime dateTime = LocalDateTime.parse(dateToParse, DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
LocalDate localDate = dateTime.toLocalDate();
LocalTime localTime = dateTime.toLocalTime();
// Compare here to your date & time
