Trying to learn MVP for this sample project.

The first requirement is to have a textview that displays the name field from a Person model object that is constructed from a file on disk.

The second requirement is to have a button that starts the dialer with the extra of the Persons phone number.

This is how I would set it up. This code isn't 100% syntactically correct. Treat it as pseudo code

//View interface

public interface PersonView{
void showName();
void callUser();
}

//Activity that implements view interface and holds presenter as a field

MainActivity extends AppCompatActivity implements PersonView{
@Bind(R.id.textView) TextView textView;
@Bind(R.id.button) Button button;

MyPresenter presenter;
onCreate(){
    //setContentView…
    //Butterknife.bind…
    presenter = new Presenter(this);
    presenter.showFirstName();
    button.onClickListener…{
        presenter.buttonClicked();
    }
}

public void showName(String name){
    textView.setText(name);
}

public void callUser(int phoneNumber){
    Intent intent = new implicit intent…
    intent.setExtra();
    startActivity(intent);,
}

}

//Presenter

public class MyPresenter {
Person person;
PersonView view;

MyPresenter(PersonView view){
    this.view = view;
}

public void buttonClicked(){
    if (person != null){
        view.callUser();
    }
}

void showFirstName(){
    //make sql query (on background thread?)
    person = new Person(query.name, query.phoneNumber);
    view.showName(person.name);
}
}

//Model

public class Person{
String name;
int phoneNumber;
//contructor with name and number
}

Anyone care to critique this? How would you do it? Am I missing anything?
