Question

How can I get a NumberFormat (or DecimalFormat) instance corresponding to an ISO 4217 currency code (such as \"EUR\" or \"USD\") in order to format

Answer 1

public class PriceHelper {
    public static String formatPrice(Context context, String currencyCode, 
                                      double price) {
        if (price == 0) {
            return context.getString(R.string.free);
        }
        Currency currency = Currency.getInstance(currencyCode);
        NumberFormat format = NumberFormat.getCurrencyInstance();
        format.setCurrency(currency);
        return format.format(price);
    }
}
