How to handle button clicks using the XML onClick within Fragments

Question

Pre-Honeycomb (Android 3), each Activity was registered to handle button clicks via the onClick tag in a Layout\'s XML:

android:onClick=\"m         


        

Answer 1

I've recently solved this issue without having to add a method to the context Activity or having to implement OnClickListener. I'm not sure if it is a "valid" solution neither, but it works.

Based on: https://developer.android.com/tools/data-binding/guide.html#binding_events

It can be done with data bindings: Just add your fragment instance as a variable, then you can link any method with onClick.

And the fragment linking code would be...

public class CustomFragment extends Fragment {

    ...

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.fragment_person_profile, container, false);
        FragmentCustomBinding binding = DataBindingUtil.bind(view);
        binding.setFragment(this);
        return view;
    }

    ...

}
