It’s time to start writing some kotlin code.

Demo 1

To use viewBinding, you have to enable it in the builde.gradle file. Unfold the “Gradle Script” section in the Project panel. Then open up the build.gradle file for the app module you’re working in. Emphasis on the word “app.”

android {
    buildFeatures {
        viewBinding true

private lateinit var binding: ActivityMainBinding
    binding = ActivityMainBinding.inflate(layoutInflater)
    val view = binding.root
binding.targetTextView.text = "52"
