Android Kotlin按collat​​or排序

Question

我想基于一个字段(player.name)对对象列表进行排序,但在西班牙语中存在重音,在订购时不必考虑这些重音.

我对列表进行排序:

strikers.sortedWith(compareBy { it.name })

但我不知道如何申请上述排序

val spanishCollator = Collator.getInstance(Locale("es", "ES"))

我怎样才能做到这一点？

问候,迭戈

Answer 1

Collator class implements Comparator interface, so you can use it to compare names as following:

strikers.sortedWith(compareBy(spanishCollator) { it.name })

Here we use it as a comparator argument of compareBy function overload, that takes both the value selector { it.name } and the comparator spanishCollator that compares these values.

Answer 2

像这样的东西？

val spanishCollator = strikers.sortedWith(Comparator { s1, s2 ->
                Collator.getInstance(Locale("es", "ES")).compare(s1,s2)
            })
