Answer 1

UiApplication.getUiApplication().pushScreen(yourNextScreen);

See the documentation on RIM website.

Answer 2

You add a listener (I have given code for the trackwheelClick listener below, but you can use others as well depending on if you want a keypress or touch etc.

I have written in the matter of implementing the event on the instantiated object itself, but you can also subclass ButtonField if you really want to.

    ButtonField closeButton = new ButtonField("Close") {
        public boolean trackwheelClick(int status, int time) {
            UiApplication.getUiApplication().pushScreen(new NextScreen());
            return true;
        }

    };
