Question

我尝试将11 Ноя 1980 г.字符串解析为日期。这个字符串是俄语格式。我正在使用此代码段来解析此问题。

Locale locale = new Locale("ru", "RU");
System.out.println(locale.toString());
DateFormat full = DateFormat.getDateInstance(DateFormat.LONG, locale);
try {
    Date date = full.parse("11 Ноя 1980 г.");
    System.out.println(date);
} catch (ParseException e) {
    e.printStackTrace();
}

在正常的java程序中运行此代码时，在解析的日期对象中输出，但在android上运行此代码会产生以下异常。

11-20 03:52:45.545 11241-11241/com.marcow.birthdaylist W/System.err: java.text.ParseException: Unparseable date: "11 Ноя 1980 г." (at offset 3)

我不明白为什么它在java和android上表现不同。

似乎俄语语言环境中的短名称在JDK和Adnroid SDK中以不同方式编码。这应该可以帮到你：

    String testDate = "11 Ноя 1980 г.";
    String[] months = {"Янв", "Фев", "Мар", "Апр", "Мая", "Июн", "Июл", "Авг", "Сен", "Окт", "Ноя", "Дек"};
    Locale ru = new Locale("ru");
    DateFormatSymbols symbols = DateFormatSymbols.getInstance(ru);
    symbols.setMonths(months);
    SimpleDateFormat format = new SimpleDateFormat("dd MMM yyyy 'г.'", ru);
    format.setDateFormatSymbols(symbols);
    try {
        Log.d(TAG, "Date is: " + format.parse(testDate));
    } catch (Exception e) {
        Log.e(TAG, "Error while parsing", e);
    }

我强烈建议在生产中使用前在各种版本的Android上进行测试！

您需要更改以下代码行：

DateFormat full = DateFormat.getDateInstance(DateFormat.LONG, locale);

到

 SimpleDateFormat full= new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss", locale);

注意：您可以在格式中描述您想要的任何格式
