It鈥檚 time to start writing some kotlin code.

Demo 1

To use viewBinding, you have to enable it in the builde.gradle file. Unfold the 鈥淕radle Script鈥 section in the Project panel. Then open up the build.gradle file for the app module you鈥檙e working in. Emphasis on the word 鈥渁pp.鈥

android {
    ...
    buildFeatures {
        viewBinding true
    }
}

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