俄语语言环境中的日期解析问题

Question

我试图将以下 11 Ноя 1980 г. 字符串解析为日期。此字符串采用俄语格式。我正在使用此代码片段来解析它。

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();
}

虽然运行此代码作为正常 java 程序在解析的日期对象中输出，但运行 android 上的此代码给出以下异常。

我不明白为什么它在 java 和 android 上表现不同。

Answer 1

您需要更改这行代码：

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

to

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

注意：这里的格式你可以描述任何你想要的格式

Answer 2

似乎俄语语言环境中月份的简称在 JDK 和 Adnroid SDK 中以不同的方式编码。这应该可以帮助您：

    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之前在 Android 的各种版本上对其进行测试！
