如何在kotlin中使用textwatcher来启用验证按钮？

import android.text.Editable
import android.text.TextWatcher

val editText = findViewById<EditText>(R.id.editText)
val verifyButton = findViewById<Button>(R.id.verifyButton)

val textWatcher = object : TextWatcher {
    override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
        // 在文本改变之前执行的逻辑
    }

    override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
        // 在文本改变时执行的逻辑
        val inputText = s.toString()
        verifyButton.isEnabled = inputText.isNotEmpty()
    }

    override fun afterTextChanged(s: Editable?) {
        // 在文本改变之后执行的逻辑
    }
}

editText.addTextChangedListener(textWatcher)
