输出Kotlin中将checkedRadioButtonID整数转换为字符串

val checkedRadioButtonID: Int = // 获取到的选中单选按钮的ID
val idAsString = checkedRadioButtonID.toString()

val checkedRadioButtonID: Int = // 获取到的选中单选按钮的ID
val idAsString = "Selected ID is $checkedRadioButtonID"

val checkedRadioButtonID: Int = // 获取到的选中单选按钮的ID
val idAsString = String.format("Selected ID is %d", checkedRadioButtonID)

// 假设这是你的单选按钮组
val radioGroup = findViewById<RadioGroup>(R.id.radioGroup)

// 设置监听器来获取选中的按钮ID
radioGroup.setOnCheckedChangeListener { group, checkedId ->
    val selectedIdAsString = checkedId.toString()
    // 现在你可以使用selectedIdAsString做任何你需要的事情
    println("Selected RadioButton ID as String: $selectedIdAsString")
}
