I have saved dates by formatting them using SimpleDateFormat.
DateFormat dateForm = new SimpleDateFormat("HH mm ss dd MMM ''yy");
String dateOutput = dateForm.format(new Date());
This uses the default Locale of the device, for example French or Spanish.
How do I convert this string (formatted for a different Locale) back to a Date object formatted with Locale.ENGLISH?
Currently when I try to convert the string back into a date, I get an unparseable date exception. This is caused by the fact the the date was saved using a different Locale
This can work for you
SimpleDateFormat sdf = new SimpleDateFormat("HH mm ss dd MMM ''yy", Locale.ENGLISH);
String dateOutput = sdf.format(new Date());
EDIT
The way I am thinking is to break it down with Calendar object and formatting it in another language. Try this
SimpleDateFormat sdf = new SimpleDateFormat("HH mm ss dd MMM ''yy", Locale.getDefault());
Calendar cal = Calendar.getInstance();
int day = 0, month = 0, year = 0, hour = 0, minute = 0, sec = 0;
String loc = Locale.getDefault().getDisplayLanguage();
try {
Date testDate = sdf.parse(date);
cal.setTime(testDate);
sec = cal.get(Calendar.SECOND);
minute = cal.get(Calendar.MINUTE);
hour = cal.get(Calendar.HOUR);
day = cal.get(Calendar.DATE);
month = cal.get(Calendar.MONTH);
year = cal.get(Calendar.YEAR);
} catch (ParseException e) {
if(loc.equals(Locale.ENGLISH.getDisplayLanguage())){
sdf = new SimpleDateFormat("HH mm ss dd MMM ''yy", Locale.FRENCH);
try {
Date testDate = sdf.parse(date);
cal.setTime(testDate);
sec = cal.get(Calendar.SECOND);
minute = cal.get(Calendar.MINUTE);
hour = cal.get(Calendar.HOUR);
day = cal.get(Calendar.DATE);
month = cal.get(Calendar.MONTH);
year = cal.get(Calendar.YEAR);
} catch (ParseException ee) {
sdf = new SimpleDateFormat("HH mm ss dd MMM ''yy", Locale.FRENCH);
try {
Date testDate = sdf.parse(date);
cal.setTime(testDate);
sec = cal.get(Calendar.SECOND);
minute = cal.get(Calendar.MINUTE);
hour = cal.get(Calendar.HOUR);
day = cal.get(Calendar.DATE);
month = cal.get(Calendar.MONTH);
year = cal.get(Calendar.YEAR);
} catch (ParseException eex) {
}
}
}
else if (loc.equals(Locale.FRENCH.getDisplayLanguage())){
sdf = new SimpleDateFormat("HH mm ss dd MMM ''yy", Locale.ENGLISH);
try {
Date testDate = sdf.parse(date);
cal.setTime(testDate);
sec = cal.get(Calendar.SECOND);
minute = cal.get(Calendar.MINUTE);
hour = cal.get(Calendar.HOUR);
day = cal.get(Calendar.DATE);
month = cal.get(Calendar.MONTH);
year = cal.get(Calendar.YEAR);
} catch (ParseException fe) {
}
}
}
cal.set(Calendar.SECOND, sec);
cal.set(Calendar.MINUTE, minute);
cal.set(Calendar.HOUR, hour);
cal.set(Calendar.YEAR, year);
cal.set(Calendar.MONTH, month);
cal.set(Calendar.DAY_OF_MONTH, day);
if(loc.equals(Locale.ENGLISH.getDisplayLanguage()))
sdf = new SimpleDateFormat("HH mm ss dd MMM ''yy", Locale.getDefault());
else if(loc.equals(Locale.FRENCH.getDisplayLanguage()))
sdf = new SimpleDateFormat("HH mm ss dd MMM ''yy", Locale.getDefault());
Date convertedLangDate = cal.getTime();
String newDate = sdf.format(convertedLangDate);
This does work for me however it is not the most elegant of solutions. Tweek it for your code.
Try this class to convert Spanish Date To English or English Date to Spanish. You can change to cultures with a small change.
