Android的字符串轉換爲日期異常

Question

當我嘗試將字符串轉換爲日期的異常：

String da="16-Jan-2014 10:25:00"; 
SimpleDateFormat sdf = new SimpleDateFormat("dd-mmm-yyyy HH:mm:SS", Locale.ENGLISH); 
Date dd = sdf.parse(da); 

什麼錯在我的代碼嗎？

java.text.ParseException: Unparseable date:"16-Jan-2014 10:25:00" (at offset 3) 

在此先感謝...

Answer 1

您使用小寫字母「M的幾個月。他們應該改爲大寫字母M's。如下所述：http://developer.android.com/reference/java/text/SimpleDateFormat.html

這樣的格局將是這樣的：

SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy HH:mm:SS", Locale.ENGLISH); 

Answer 2

考慮例

String text = "2014-01-17T00:00:00.000-0500"; 
DateFormat sdf = new SimpleDateFormat("yyyy-MMM-dd'T'HH:mm:ss.SSSZ"); 

希望在此之後能夠幫助

正如@Tim Kranen酒店所提，月份格式爲大寫字母。所以它應該是MMM。

要理解格式化幾個月考慮這短短的代碼 -

/* 
    Formatting month using SimpleDateFormat 
    This example shows how to format month using Java SimpleDateFormat class. Month can 
    be formatted in M, MM, MMM and MMMM formats. 
*/ 


import java.text.SimpleDateFormat; 
import java.util.Date; 

public class FormattingMonth { 

    public static void main(String[] args) { 

    //create Date object 
    Date date = new Date(); 

    //formatting month in M format like 1,2 etc 
    String strDateFormat = "M"; 
    SimpleDateFormat sdf = new SimpleDateFormat(strDateFormat); 

    System.out.println("Current Month in M format : " + sdf.format(date)); 

    //formatting Month in MM format like 01, 02 etc. 
    strDateFormat = "MM"; 
    sdf = new SimpleDateFormat(strDateFormat); 
    System.out.println("Current Month in MM format : " + sdf.format(date)); 

    //formatting Month in MMM format like Jan, Feb etc. 
    strDateFormat = "MMM"; 
    sdf = new SimpleDateFormat(strDateFormat); 
    System.out.println("Current Month in MMM format : " + sdf.format(date)); 

    //formatting Month in MMMM format like January, February etc. 
    strDateFormat = "MMMM"; 
    sdf = new SimpleDateFormat(strDateFormat); 
    System.out.println("Current Month in MMMM format : " + sdf.format(date)); 

    } 
} 

/* 
Typical output would be 
Current Month in M format : 2 
Current Month in MM format : 02 
Current Month in MMM format : Feb 
Current Month in MMMM format : February 
* 

檢查Java Date Formatting舉例如上所述理解的格式。
