NumberRangeFormatter


public abstract class NumberRangeFormatter
extends Object

java.lang.Object
   ↳ android.icu.number.NumberRangeFormatter


The main entrypoint to the formatting of ranges of numbers, including currencies and other units of measurement.

Usage example:

 NumberRangeFormatter.with()
         .identityFallback(RangeIdentityFallback.APPROXIMATELY_OR_SINGLE_VALUE)
         .numberFormatterFirst(NumberFormatter.with().unit(MeasureUnit.METER))
         .numberFormatterSecond(NumberFormatter.with().unit(MeasureUnit.KILOMETER))
         .locale(ULocale.UK)
         .formatRange(750, 1.2)
         .toString();
 // => "750 m - 1.2 km"
 

Like NumberFormatter, NumberRangeFormatter instances (i.e., LocalizedNumberRangeFormatter and UnlocalizedNumberRangeFormatter) are immutable and thread-safe. This API is based on the fluent design pattern popularized by libraries such as Google's Guava.
