java - Android/Java 日期格式化和拆分

Question

我有一个日期作为字符串“18.07.2013 15:31:10”，我希望它像

string DAY_OF_WEEK_IN_MONTH = "18";
string DAY_OF_WEEK = "Thursday";
string MONTH_IN_YEAR = "July";
string HOUR ="15:31";

我该怎么做？我看过格式化帖子，但不知道如何分割日期。

Answer 1

SimpleDateFormat format  = new SimpleDateFormat("dd.MM.yyyy HH:mm:ss");
Date date = format.parse("18.07.2013 15:31:10");
Calendar calendar = Calendar.getInstance();
calenadr.setTime(date);

然后您可以使用它calendar来获取您需要的信息。

int dayOfTheWeek = calendar.get(Calendar.DAY_OF_WEEK_IN_MONTH);

Answer 2

   SimpleDateFormat format  = new SimpleDateFormat("dd.MM.yyyy HH:mm:ss");
   Date date = format.parse("18.07.2013 15:31:10");
   Calendar cal = Calendar.getInstance();
   cal.setTime(date);             
   int day  = cal.get(Calendar.DATE);
   int month  = cal.get(Calendar.MONTH) + 1;
   int year = cal.get(Calendar.YEAR);        
   System.out.println("day:" + day);
   System.out.println("month :"+month);       
   System.out.println("year: "+year);
   System.out.println(new SimpleDateFormat("MMM").format(cal.getTime()));
   System.out.println(new SimpleDateFormat("EEE").format(cal.getTime()));
   System.out.println(new SimpleDateFormat("HH:mm").format(cal.getTime()));
