Agregue build.gradle (módulo):

...buildFeatures {
viewBinding true
}
}

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
}
}

O en Java:

public class MainActivity extends AppCompatActivity {
private ActivityMainBinding binding;
@Override
protected void onCreate(Bundle savedInstanceState) {

binding = ActivityMainBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
}
