在java中将字符串转换为Date

Question

我正在尝试将字符串解析为Android应用程序中的日期字段,但我似乎无法将其正确解析.这是我想要转换为日期"03/26/2012 11:49:00 AM"的字符串.我正在使用的功能是:

private Date ConvertToDate(String dateString){
    SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss aa");
    Date convertedDate = new Date();
    try {
        convertedDate = dateFormat.parse(dateString);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return convertedDate;
}

但我不断得到3/1/112 11:49AM结果.

Answer 1

我猜你显示数据的方式是错误的,因为对我来说:

    String dateString = "03/26/2012 11:49:00 AM";
    SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss aa");
    Date convertedDate = new Date();
    try {
        convertedDate = dateFormat.parse(dateString);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    System.out.println(convertedDate);

打印:

Mon Mar 26 11:49:00 EEST 2012

当我使用Locale.US参数时,它没问题SimpleDateFormat

String dateString = "15 May 2013 17:38:34 +0300";
System.out.println(dateString);

SimpleDateFormat dateFormat = new SimpleDateFormat("dd MMM yyyy HH:mm:ss Z", Locale.US);
DateFormat targetFormat = new SimpleDateFormat("dd MMM yyyy HH:mm", Locale.getDefault());
String formattedDate = null;
Date convertedDate = new Date();
try {
     convertedDate = dateFormat.parse(dateString);
System.out.println(dateString);
formattedDate = targetFormat.format(convertedDate);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
 System.out.println(convertedDate);
