Integration Step Used Binding in Kotlin

1. Add viewBinding true build.gralde (Module)

android {
   ...
   buildFeatures {
      viewBinding true
   }
}

2. Activity Kotlin Class

class MainActivity : AppCompatActivity() {

    /** Add this */
    private lateinit var binding: ActivityMainBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        /** Add this */
        binding = ActivityMainBinding.inflate(layoutInflater)

        /** Change this */
        setContentView(binding.root)

        /** Without findViewById */
        binding.textView.text = "Bye bye findViewById"
    }
}

3. Activity Java Class

public class MainActivity extends AppCompatActivity {

    /** Add this */
    private ActivityMainBinding binding;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        /** Add this */
        binding = ActivityMainBinding.inflate(getLayoutInflater());

        /** Change this */
        setContentView(binding.getRoot());

        /** Without findViewById */
        binding.textView.setText("Bye bye findViewById");
    }
}

binding in kotlin can be used directly without initializing findViewById on widgets in layout xml
