editableText is not working in android studio-CodePudding

I want to take Input from user(their name) with editableText just like the below video(watch at 8:24). But, I am not able to take input because android studio is not recognizing "editableText". Am i missing something?

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

CodePudding user response：

Android kotlin extensions removed at Android studio 4.1V.

I recommend use the ViewBinding or DataBinding.

This is a good reference.

https://android-developers.googleblog.com/2020/11/the-future-of-kotlin-android-extensions.html

ViewBinding : https://developer.android.com/topic/libraries/view-binding?hl=ko

DataBinding : https://developer.android.com/topic/libraries/data-binding

CodePudding user response：

As Android kotlin extensions is deprecated and removed you may use View binding, Data binding as suggested by Seungho Kang

OR you can declare variable as shown below.

fun createBirthdayCard(view: View){
       val editText=findViewById<EditText>(R.id.nameInput)
       val name = editText.editableText.toString()
    }
