Not able to make click event in android data binding

In later versions of the DataBinding library you can just bind to your click event like this:

android:onClick="@{() -> viewModel.save()}"

Then, in your viewmodel you can just add a listener like this:

public void save(){
 ...
 }

Make your MyHandlers interface from class.

public class MyHandlers {
    public void onShowToast(View view);
} 

Implement it in your Activity or Fragment, in your case it will be as follows

public class View extends AppCompatActivity implements ViewContract.requiredMethods, MyHandlers{

    ViewModel mModel;
    ActivityMainBinding binding;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //Setting the layout
        binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
        mModel=new ViewModel(getContext());
        binding.setUser(mModel);
        binding.setHandlers(this);

    }        

    @Override
    public void onShowToast(View view) {
        Toast.makeText(view,"Clicked",Toast.LENGTH_SHORT).show();
    }
}

Override your interface method onShowToast and set the handler for your binding, and that's it, you are done with click events
