如何将日期时间字符串转换为整数数据类型？ [英] How can I convert a datetime string into an integer datatype?

问题描述

String timerStop1 = String.format("%02d", hours) + ":"+String.format("%02d", minutes) + ":"
                  + String.format("%02d", seconds);

我正在使用上面的串联字符串值，我想将其转换为整数在我的Android应用程序中使用。我该怎么做？

I'm taking the above concatenated string value and I want to convert it into an integer to use in my android application. How do I do this?

推荐答案

第一步是将时间换成 HH：MM：SS 格式（这是你的字符串的格式）到秒的格式：

A first step will be to convert the time in HH:MM:SS format (which is how your string is formatted) to that of seconds as per the following:

String timerStop1 = String.format("%02d", hours) + ":" + String.format("%02d", minutes) + ":" + String.format("%02d", seconds);
String[] timef=timerStop1.split(":");  

int hour=Integer.parseInt(timef[0]);  
int minute=Integer.parseInt(timef[1]);  
int second=Integer.parseInt(timef[2]);  

int temp;  
temp = second + (60 * minute) + (3600 * hour);  

System.out.println("seconds " + temp); 

但是，这只会将时间作为秒（整数），而不是时间戳！

更新：

而且，正如科林指出的那样，鉴于您已经拥有访问权限变量：小时，分钟，秒 - 为什么不像他建议的那样 - 这是完全正确的？

And, as Colin pointed out, given that you already have access to the variables: hours, minutes, seconds - why not do it like what he suggested - which is completely correct?

那是因为OP想要知道如何将HH：MM：SS字符串转换为整数 - 如果是这样，那么这是最通用的方式，IMO。

That's because the OP wants to know how to convert an HH:MM:SS string to an integer - if so, then this is the most general way in which to do so, IMO.
