How to bind views in Fragment using DataBindingUtil?

In an activity can bind and access myView which is a subview in the layout like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);

   ActivityExampleBinding views = DataBindingUtil.setContentView(this, R.layout.activity_example);
   views.myView.doSomething();
}

How can I do that in a Fragment? I can return the inflated root view like this:

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

    ViewDataBinding views = DataBindingUtil.inflate(inflater, R.layout.fragment_example, container,false);
    return views.getRoot();
}

But how can I access a subview in the layout?

Your current code is fine, if you want to stick with it — just change the view variable to be a FragmentExampleBinding (matching your fragment_example layout resource name).

Alternatively, use FragmentExampleBinding.inflate(), as you do not need to pass in the layout resource ID.
