kotlin - 检查数组是否包含子字符串？

Question

我有这个数组:

val array : MutableList<String> =  mutableListOf("laptop on floor", "man is thomas")

如何检查它是否包含以下字符串: flo？ (在第一个元素中)

Answer 1

试试这个代码片段

val array : MutableList<String> =  mutableListOf("laptop on floor", "man is thomas")

val doesContain1 = array.indexOfFirst { it.contains("flo") } >= 0
// or
val doesContain2 = array.find { it.contains("flo") } != null
// or
val doesContain3 = array.any { it.contains("flo") }
