You can't override it except in a derived class. So you need to create your own class that extends one of the Manager classes.

The problem then is that you can not set a new MainManager for the MainScreen. That's annoying. The solution I came up with was to create a derived MainScreen class that creates it's own new Manager and adds Fields to that Manager instead of the default one already created by the MainScreen.

It's a bit tricky, but it works. Any fields you add are painted over the top of the background bitmap. Here's some sample code...

First the new Manager class:

class NewVerticalFieldManager extends VerticalFieldManager {
    Bitmap bkgrndBmp = Bitmap.getBitmapResource("background.png");
    
    NewVerticalFieldManager() { 
        super();
    }
    
    protected void paintBackground(Graphics g){
            if(bkgrndBmp != null){
                    g.rop(Graphics.ROP_SRC_ALPHA_GLOBALALPHA,
                          (this.getWidth() / 2) - (bkgrndBmp .getWidth() /2),
                          (this.getHeight() / 2) - (bkgrndBmp .getHeight() /2),
                          bkgrndBmp .getWidth(),
                          bkgrndBmp .getHeight(),
                          bkgrndBmp ,0,0);
            }
    }
}

Now the new MainScreen class.

class NewMainScreen extends MainScreen {
    
    NewVerticalFieldManager manager = new NewVerticalFieldManager();
    
    NewMainScreen() {  
        super();
        super.add(manager);
    }
    
    public void add(Field field){
        manager.add(field);
    }    
}
