Question

我要创建的是一个自定义AlertDialogBox，我想针对其调用class AlertBox(context: Context) : BaseDialogHelper() { override val dialogView: View by lazy { LayoutInflater.from(context).inflate(R.layout.custom_dialog, null) } override val builder: AlertDialog.Builder = AlertDialog.Builder(context).setView(dialogView) val txt_title: TextView by lazy { dialogView.findViewById<TextView>(R.id.txt_title) } val txt_message: TextView by lazy { dialogView.findViewById<TextView>(R.id.txt_message) } val btn_ok: Button by lazy { dialogView.findViewById<Button>(R.id.btn_done) } val btn_cancel: Button by lazy { dialogView.findViewById<Button>(R.id.btn_cancel) } //These are the methods that i want to change fun setTitle(title: String) { txt_title.text = title } fun setMessage(message: String) { txt_message.text = message } fun onOkButtonClickListener(func: (() -> Unit)? = null) = with(btn_ok) { setClickListenerToButton(func) } fun onCancelButtonClickListener(func: (() -> Unit)? = null) = with(btn_cancel) { setClickListenerToButton(func) } private fun View.setClickListenerToButton(func: (() -> Unit)?) = setOnClickListener { func?.invoke() dialog?.dismiss() } }的“ setTitle（）”方法。我当前的AlertDialog代码如下所示

我想创建一个类似于TextView.setText（String）的类成员函数，该函数可以作为TextView.text =“”来调用。可以对自定义类执行此操作吗？？

您需要定义一个属性：

var text: String
    get() = txt_title.text
    set(value) { txt_title.text = value }
