Answer 1

// inside of your current screen:
ButtonField btn = new ButtonField("Go to next screen");
btn.setChangeListener(new FieldChangeListener() {
    public void fieldChanged(Field f, int arg1) {
        NextScreen ns = new NextScreen();
        UiApplication.getUiApplication().pushScreen(ns);
    }
});
add(btn);
