ViewBinding - how to get binding for included layouts?

Question

While working with ViewBinding I come across few not documented cases.

First: How to get binding for included generic view layout parts, main binding see only items

Answer 1

Your first question, that is working with an included layout using ViewBinding can be solved so easily.

Here is a sample main_fragment.xml file

And MainFragment.java can be like this

public class MeaningFragment extends Fragment {

    private MainFragmentBinding binding;
    private ToolbarBinding toolbarBinding;

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

        binding = MainFragmentBinding.inflate(inflater, container, false);
        toolbarBinding = binding.toolbar;

        return binding.getRoot();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();

        toolbarBinding = null;
        binding = null;
    }
}

Now, you have two bindings. one of them is the default and the next one is from the included layout.
