Transition between many Views ?

Question

hi I've found a source code for android.

http://code.google.com/p/secrets-for-android/source/browse/trunk/src/net/tawacentral/roger/secrets/SecretsListActivity.java?r=13

In this code, you can see following line :

..... private View root; // root of the layout for this activity private View edit; // root view for the editing layout .....

@Override public void onCreate(Bundle state) { super.onCreate(state);

...

root = findViewById(R.id.list_container);
edit = findViewById(R.id.edit_layout);

...

}

private void animateToEditView() { assert(!isEditing); isEditing = true;

// Cancel any toast that may currently be displayed.
if (null != toast)
  toast.cancel();

View list = getListView();
int cx = root.getWidth() / 2;
int cy = root.getHeight() / 2;
Animation animation = new Flip3dAnimation(list, edit, cx, cy, true);
animation.setAnimationListener(new AnimationListener() {
  @Override
  public void onAnimationEnd(Animation animation) {
    if (0 == secretsList.getCount()) {
      showToast(getText(R.string.edit_instructions));
    }
  }
  @Override
  public void onAnimationRepeat(Animation animation) {
  }
  @Override
  public void onAnimationStart(Animation animation) {
  }
});

root.startAnimation(animation);

}

In above code :

root.startAnimation(animation);

Can this code call another view from current view ?

If so, Do I need to initialize screen (to transit to) in onCreate method ?
