SimpleDateFormat.applyPattern介绍

[英]Changes the pattern of this simple date format to the specified pattern which uses non-localized pattern characters.
[中]将此简单日期格式的模式更改为使用非本地化模式字符的指定模式。

代码示例

final String OLD_FORMAT = "dd/MM/yyyy";
final String NEW_FORMAT = "yyyy/MM/dd";

// August 12, 2010
String oldDateString = "12/08/2010";
String newDateString;

SimpleDateFormat sdf = new SimpleDateFormat(OLD_FORMAT);
Date d = sdf.parse(oldDateString);
sdf.applyPattern(NEW_FORMAT);
newDateString = sdf.format(d);

static String timeAsGmt() {
 SimpleDateFormat sdf = new SimpleDateFormat();
 sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
 sdf.applyPattern("dd MMM yyyy HH:mm:ss z");
 return sdf.format(Calendar.getInstance().getTime());
}
