need space between currency symbol and amount

I'm trying to print INR format currency like this:

NumberFormat fmt = NumberFormat.getCurrencyInstance();
fmt.setCurrency(Currency.getInstance("INR"));
fmt.format(30382.50);

shows Rs30,382.50开发者_开发知识库, but in India its written as Rs. 30,382.50(see http://www.flipkart.com/) how to solve without hardcoding for INR?

It's a bit of a hack but in a very similar situation, I used something like this

NumberFormat format = NumberFormat.getCurrencyInstance(new Locale("en", "in"));
String currencySymbol = format.format(0.00).replace("0.00", "");
System.out.println(format.format(30382.50).replace(currencySymbol, currencySymbol + " "));

all the currencies I had to deal with involved two decimal places so i was able to do "0.00" for all of them but if you plan to use something like Japanese Yen, this has to be tweaked. There is a NumberFormat.getCurrency().getSymbol(); but it returns INR instead for Rs. so that cannot be used for getting the currency symbol.

An easier method, kind of workaround. For my locale, the currency symbol is "R$"

public static String moneyFormatter(double d){

    DecimalFormat fmt = (DecimalFormat) NumberFormat.getInstance();
    Locale locale = Locale.getDefault();
    String symbol = Currency.getInstance(locale).getSymbol(locale);
    fmt.setGroupingUsed(true);
    fmt.setPositivePrefix(symbol + " ");
    fmt.setNegativePrefix("-" + symbol + " ");
    fmt.setMinimumFractionDigits(2);
    fmt.setMaximumFractionDigits(2);
    return fmt.format(d);
}

Input:

moneyFormatter(225.0);

Output:

"R$ 225,00"

See if this works:

DecimalFormat fmt = (DecimalFormat) NumberFormat.getInstance();
fmt.setGroupingUsed(true);
fmt.setPositivePrefix("Rs. ");
fmt.setNegativePrefix("Rs. -");
fmt.setMinimumFractionDigits(2);
fmt.setMaximumFractionDigits(2);
fmt.format(30382.50);

Edit: Fixed the first line.

I dont think you can.

You should take a look at http://site.icu-project.org/

There might be better locale-specific currency formatting provided by icu4j.

I don't see any easy way to do this. Here's what I came up with...

The key to getting the actual currency symbol seems to be passing the destination locale into Currency.getSymbol:

currencyFormat.getCurrency().getSymbol(locale)

Here's some code that seems like it mostly works:

public static String formatPrice(String price, Locale locale, String currencyCode) {

    NumberFormat currencyFormat = NumberFormat.getCurrencyInstance(locale);
    Currency currency = Currency.getInstance(currencyCode);
    currencyFormat.setCurrency(currency);

    try {
        String formatted = currencyFormat.format(NumberFormat.getNumberInstance().parse(price));
        String symbol = currencyFormat.getCurrency().getSymbol(locale);

        // Different locales put the symbol on opposite sides of the amount
        // http://en.wikipedia.org/wiki/Currency_sign
        // If there is already a space (like the fr_FR locale formats things),
        // then return this as is, otherwise insert a space on either side
        // and trim the result
        if (StringUtils.contains(formatted, " " + symbol) || StringUtils.contains(formatted, symbol + " ")) {
            return formatted;
        } else {
            return StringUtils.replaceOnce(formatted, symbol, " " + symbol + " ").trim();
        }
    } catch (ParseException e) {
        // ignore
    }
    return null;
}

Sorry for Kotlin I came here from android). As I understood there is no correct solutions for that, so that's why my solution is also hack)

fun formatBalance(
    amount: Float,
    currencyCode: String,
    languageLocale: Locale
): String {

amount can be String as well.

    val currencyFormatter: NumberFormat = NumberFormat.getCurrencyInstance(languageLocale)
    currencyFormatter.currency = Currency.getInstance(currencyCode)
    val formatted = currencyFormatter.format(amount)

formatted will get amount with currency from correct side but without space. (Example: 100$, €100)

    val amountFirstSymbol = amount.toString()[0]
    val formattedFirstSymbol = formatted[0]

    val currencySymbolIsBefore = amountFirstSymbol != formattedFirstSymbol

Then I use this little hack to understand if currency symbol is before amount. So for example amount is 100 then amountFirstSymbol will be "1". And if formatted is 100$ then formattedFirstSymbol also will be "1". That means we can put our currency symbol behind amount but now with space.

    val symbol = currencyFormatter.currency?.symbol
    return if (currencySymbolIsBefore) "$symbol $amount"
    else "$amount $symbol"

Here what I do to add space after currency symbol:

DecimalFormat numberFormat = (DecimalFormat) NumberFormat.getCurrencyInstance(new Locale("id", "ID"));

DecimalFormatSymbols symbol = new DecimalFormatSymbols(new Locale("id", "ID"));
// Add space to currency symbol
symbol.setCurrencySymbol(symbol.getCurrencySymbol() + " ");

numberFormat.setDecimalFormatSymbols(symbol);
