Question

在阅读了Date formatting based on user locale on android对德语的接受答案之后，我测试了以下内容：

@Override
protected void onResume() {
    super.onResume();
    String dateOfBirth = "02/26/1974";
    SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
    Date date = null;
    try {
        date = sdf.parse(dateOfBirth);
    } catch (ParseException e) {
        // handle exception here !
    }
    // get localized date formats
    DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getApplicationContext());
    String s = dateFormat.format(date);
    dateTV.setText(s);
}

这里dateOfBirth是一个英国约会。如果我将手机的语言改为德语，我会看到02.26.1974。根据{{3}}，适当的本地化德国日期格式是dd.mm.yyyy，所以我希望看到＆＃34; 26.02.1974＆＃34;。

这导致了我的问题，是否有办法完全本地化日期，或者这是一个手动过程，我必须通过我的应用程序了解日期，时间等？

    String dateOfBirth = "02/26/1974";
    SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
    Date date = null;
    try {
        date = sdf.parse(dateOfBirth);
    } catch (Exception e) {
        // handle exception here !
    }
    // get localized date formats
    Log.i(this,"sdf default: "+new SimpleDateFormat().format(date)); // using my phone locale
    DateFormat dateFormat = DateFormat.getDateInstance(DateFormat.DEFAULT, Locale.US);
    Log.i(this,"dateFormat US DEFAULT: "+dateFormat.format(date));
    dateFormat = DateFormat.getDateInstance(DateFormat.DEFAULT, Locale.GERMAN);
    Log.i(this,"dateFormat GERMAN DEFAULT: "+dateFormat.format(date));
    dateFormat = DateFormat.getDateInstance(DateFormat.DEFAULT, Locale.CHINESE);
    Log.i(this,"dateFormat CHINESE DEFAULT: "+dateFormat.format(date));
    dateFormat = DateFormat.getDateInstance(DateFormat.SHORT, Locale.US);
    Log.i(this,"dateFormat US SHORT: "+dateFormat.format(date));
    dateFormat = DateFormat.getDateInstance(DateFormat.SHORT, Locale.GERMAN);
    Log.i(this,"dateFormat GERMAN SHORT: "+dateFormat.format(date));
    dateFormat = DateFormat.getDateInstance(DateFormat.SHORT, Locale.CHINESE);
    Log.i(this,"dateFormat CHINESE SHORT: "+dateFormat.format(date));

输出是：

 sdf default: 26.02.74 0:00
 dateFormat US DEFAULT: Feb 26, 1974
 dateFormat GERMAN DEFAULT: 26.02.1974
 dateFormat CHINESE DEFAULT: 1974-2-26
 dateFormat US SHORT: 2/26/74
 dateFormat GERMAN SHORT: 26.02.74
 dateFormat CHINESE SHORT: 74-2-26

在android中本地化日期
