CVM and other Practices

One of the reasons I started watching the videos here at Treehouse was because of a YouTube video of Ben Jakuben giving a brief summary of control-view-model. I thought that any place that teaches this (even as a concept worth thinking about) must be a class joint.

Jumping ahead to today, I am working on code for the forum contest. A work-around has led to code that is ... well ... awkward. I've listed some pseudo-code below that demonstrates my question in as simple a manner as possible. I would love to hear peoples opinions: With CVM, should the control get the information from the model and then the control updates the view (what I understood)? Or is it normal for the model update the view.

Cheers,

--- code below ---

I have a class clock (i.e. the model):

public class clock() {
  private View mView;
  private String mTime;

  clock(View view) {
    mView = view;
    mTime = "12:00"
  }

  void updateDisplay() {
    mView.setText(mTime);
  }
}

The main activity (i.e. the control) initiates an update by calling mClock.updateDisplay():

public class MainActivity extends Activity {
  private Clock mClock;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    View view = findViewById(R.id.view);
    mClock = new Clock(view);    
  }

  @Override
  protected void onResume() {
    super.onResume();
    mClock.updateDisplay();
  }
}

What I would prefer is if the clock (i.e. the model) did not own a copy of the view and did not update the view:

public class clock() {
  private String mTime;

  clock() {
    mTime = "12:00"
  }

  String toString() {
    return mTime;
  }
}

This way, the main activity (the control) retrieves information from the clock (i.e. the model) and then it updates the view:

public class MainActivity extends Activity {
  private View mView;
  private Clock mClock;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mView = findViewById(R.id.view);
    mClock = new Clock();
  }

  @Override
  protected void onResume() {
    super.onResume();
    String time = mClock.toString();
    mView.setText(time);
  }
}

Make sense?
