Currency

public class Currency
extends MeasureUnit

java.lang.Object
   ↳ android.icu.util.MeasureUnit
     ↳ android.icu.util.Currency


A class encapsulating a currency, as defined by ISO 4217. A Currency object can be created given a Locale or given an ISO 4217 code. Once created, the Currency object can return various data necessary to its proper display:

  • A display symbol, for a specific locale
  • The number of fraction digits to display
  • A rounding increment
The DecimalFormat class uses these data to display currencies.

Note: This class deliberately resembles java.util.Currency but it has a completely independent implementation, and adds features not present in the JDK.

getKeywordValuesForLocale

added in API level 24
public static final String[] getKeywordValuesForLocale (String key, 
                ULocale locale, 
                boolean commonlyUsed)

Given a key and a locale, returns an array of values for the key for which data exists. If commonlyUsed is true, these are the values that typically are used with this locale, otherwise these are all values for which data exists. This is a common service API.

The only supported key is "currency", other values return an empty array.

Currency information is based on the region of the locale. If the locale does not indicate a region, ULocale.addLikelySubtags(ULocale) is used to infer a region, except for the 'und' locale.

If commonlyUsed is true, only the currencies known to be in use as of the current date are returned. When there are more than one, these are returned in preference order (typically, this occurs when a country is transitioning to a new currency, and the newer currency is preferred), see Unicode TR#35 Sec. C1. If commonlyUsed is false, all currencies ever used in any locale are returned, in no particular order.

Parameters
key String: key whose values to look up. the only recognized key is "currency"

locale ULocale: the locale

commonlyUsed boolean: if true, return only values that are currently used in the locale. Otherwise returns all values.

Returns
String[] an array of values for the given key and the locale. If there is no data, the array will be empty.

                int nameStyle, 
                String pluralCount, 
                boolean[] isChoiceFormat)

Returns the display name for the given currency in the given locale. For example, the SYMBOL_NAME for the USD currency object in the en_US locale is "$". The PLURAL_LONG_NAME for the USD currency object when the currency amount is plural is "US dollars", such as in "3.00 US dollars"; while the PLURAL_LONG_NAME for the USD currency object when the currency amount is singular is "US dollar", such as in "1.00 US dollar".

Parameters
locale ULocale: locale in which to display currency

pluralCount String: plural count string for this locale

isChoiceFormat boolean: fill-in; isChoiceFormat[0] is set to true if the returned value is a ChoiceFormat pattern; otherwise it is set to false
