blackberry - Better method of hadling navigation flow in app -

I have different screens in my app and for each screen, I have a button that is a new screen One button is clicked to push -

  QuizButton .set change listener (new field change listener) {change public zeros field (field field, favored context) {UiApplication .getUiApplication () .PushScreen (new customsin ());}});   
 Is there another 'MVC-like' method to handle navigation flow or not?   
 
 
 whenever you want to push a new screen  
 you create a square Which enhances the main screen and whatever manual object takes, the constructor in the constructor and in the logic presses the next screen as the constructor. << P> 
 
 So whenever you are ready to navigate this to your project, then create the object of this custom class and send the screen object as an argument to the constructor  < / Div>
