Blackberry - close splash screen on any key

Question

I am trying to adapt a piece of existing code. I am trying to remove a timer on a splash screen and change it to "press any key to continue" type screen. I need some help with the push/popscreen logic and listening for a keystroke on the splash screen. Here is extract from the code.

public class MenuMain_Pca extends UiApplication {
    public static void main(String[] args) {
     MenuMain_Pca myStart = new MenuMain_Pca();
     myStart.enterEventDispatcher();
    }
    public MenuMain_Pca() {
     Screen_Splash_Screen wScreen = new Screen_Splash_Screen();
     this.pushScreen(wScreen);
     this.popScreen(wScreen);
     MenuMain_Pca.this.pushScreen(new HomeScreen());
    }
}

class Screen_Splash_Screen extends MainScreen implements KeyListener {
    public Screen_Splash_Screen() {
     super(DEFAULT_MENU | DEFAULT_CLOSE);
     Bitmap b240 = new Bitmap(240, 163);
     b240 = Bitmap.getBitmapResource("image1.png");
     BitmapField bf = new BitmapField(b240);
     bf.setSpace(Display.getWidth() / 2 - b240.getWidth() / 2, 0);
     add(bf);
    }
    public boolean keyChar(char key, int status, int time) {
     return true;
    }
    public boolean keyDown(int keycode, int time) {
     return true;
    }
    public boolean keyRepeat(int keycode, int time) {
     return true;
    }
    public boolean keyStatus(int keycode, int time) {
     return true;
    }
    public boolean keyUp(int keycode, int time) {
     return true;
    }
}

class HomeScreen extends MainScreen implements FieldChangeListener {
    private ButtonField button1 = null;
    public HomeScreen() {
     super(DEFAULT_MENU | DEFAULT_CLOSE);
     setTitle(new LabelField("label1", LabelField.ELLIPSIS
       | LabelField.USE_ALL_WIDTH));
     int screenWidth = Display.getWidth() * 95 / 100;
     button1 = new ButtonField("Button1");
     button1.setChangeListener(this);
     add(button1);
    }

    public void fieldChanged(Field field, int context) {
     if (field == (Field) button1)
      UiApplication.getUiApplication().pushScreen(new menu1(1));
    }

    // ask user if he really wants to leave...
    public boolean onClose() {
     boolean retval = false;
     String label = "Are you sure you want to Exit now?";
     int response = Dialog.ask(Dialog.D_YES_NO, label, Dialog.YES);
     if (response == Dialog.YES) {
      System.exit(0);
      retval = true;
     }
     return retval;
    }
}

Try to use keyDown event in splash screen, like this:

public boolean keyDown(int keycode, int time) {
  getUiEngine().pushScreen(new HomeScreen());
  getUiEngine().popScreen(this);
 return true;
}
