区分大小写Kotlin/ignoreCase

问题描述

我试图忽略字符串的区分大小写.例如，用户可以放置巴西"或巴西"，然后就会触发乐趣.我该如何执行呢?我是Kotlin的新手.

I am trying to ignore case sensitivity on a string. For example, a user can put "Brazil" or "brasil" and the fun will trigger. How do I implement this? I am new to Kotlin.

fun questionFour() {
    val edittextCountry = findViewById<EditText>(R.id.editTextCountry)
    val answerEditText = edittextCountry.getText().toString()

    if (answerEditText == "Brazil") {
        correctAnswers++
    }

    if (answerEditText == "Brasil") {
        correctAnswers++
    }
}

编辑

另一个人帮我这样写.我现在对这种方式的疑问是是否有一种更干净的方式编写这种方式?"

EDIT

Another person helped me write like this. My question now about this way is "Is there a cleaner way to write this?"

fun questionFour() {
    val edittextCountry = findViewById<EditText>(R.id.editTextCountry)
    val answerEditText = edittextCountry.getText().toString()

    if (answerEditText.toLowerCase() == "Brazil".toLowerCase() || answerEditText.toLowerCase() == "Brasil".toLowerCase()) {
        correctAnswers++
    }
}

答案

fun questionFour() {

        val edittextCountry = findViewById<EditText>(R.id.editTextCountry)
        val answerEditText = edittextCountry.getText().toString()

        if (answerEditText.equals("brasil", ignoreCase = true) || answerEditText.equals("brazil", ignoreCase = true)) {
            correctAnswers++
        }
    }

推荐答案

您可以调用 equals 函数直接运行，它将允许您指定可选参数ignoreCase:

if (answerEditText.equals("brasil", ignoreCase = true)) {
    correctAnswers++
}
