android - 使用 getBestDateTimePattern()

Question

根据新闻约Android 4.3

To assist you with managing date formatting across locales, Android 4.3 includes a new getBestDateTimePattern() method that automatically generates the best possible localized form of a Unicode UTS date for a locale that you specify. It’s a convenient way to provide a more localized experience for your users.

如何使用此方法？我找不到它。

7.5 年后，这里有一个带有实际示例的答案! ;-)

Locale locale = Locale.getDefault();
String skeleton = DateFormat.getBestDateTimePattern(locale, "MMMM d, YYYY");

然后，使用 java.time:

Instant.now().atZone(ZoneId.systemDefault()).format(DateTimeFormatter.ofPattern(skeleton));

或者使用遗留类:

Date now = Calendar.getInstance().getTime();
SimpleDateFormat dateTimeFormatter = new SimpleDateFormat(skeleton, locale);
dateTimeFormatter.setTimeZone(TimeZone.getDefault());
dateTimeFormatter.applyLocalizedPattern(skeleton);
dateTimeFormatter.format(now);
