kotlinde şu kodu yazdım:
package com.example.deneme
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.View
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
fun degistir(view : View){
textView.text=“Merhaba android”
}
}
fakat textview i import etmiyor.
