Correct way to use Toolbar Listener

Question

Hello I can't found an answer to my question. I am using a Toolbar, so I create it in OnCreate like this:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle("Toolbar");
toolbar.inflateMenu(R.menu.menu_examen);
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
    @Override
    public boolean onMenuItemClick(MenuItem item) {
        return false;
    }
});

But I noticed that if I use a lot of options my OnCreate becomes very mesy. I love order so I made this listener out of OnCreate:

Toolbar.OnMenuItemClickListener toolbarListener = new Toolbar.OnMenuItemClickListener() {
        @Override
        public boolean onMenuItemClick(MenuItem item) {
            switch (item.getItemId()){
                case R.id.opcion1:
                    Toast.makeText(ExamenActivity.this,"Opcion 1",Toast.LENGTH_SHORT).show();
                    break;
                default:
            }
            return false;
        }
    };

And then on my OnCreate the toolbar is:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
//setSupportActionBar(toolbar);
toolbar.setTitle("Quitar esta wea");
toolbar.inflateMenu(R.menu.menu_examen);
toolbar.setOnMenuItemClickListener(toolbarListener);

This is working but Is this correct? Does this have a name? Thank you. I know it is a simple question but I want to it right

Yea that is better, you can do it even better without extra variable as in

class YourActivity extends Activity implements Toolbar.OnMenuItemClickListener{

onCreate(){
      ...
      Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
     //setSupportActionBar(toolbar);
      toolbar.setTitle("Quitar esta wea");
      toolbar.inflateMenu(R.menu.menu_examen);
      toolbar.setOnMenuItemClickListener(this);
      ...
}

@Override
public boolean onMenuItemClick(MenuItem item) {
            switch (item.getItemId()){
                case R.id.opcion1:
                    Toast.makeText(ExamenActivity.this,"Opcion 1",Toast.LENGTH_SHORT).show();
                    break;
                default:
            }
            return false;
        }
}
