If InputListener is a Java Interface, JRuby has a feature where you can use a Ruby block for that, documented here:
https://github.com/jruby/jruby/wiki/CallingJavaFromJRuby#closure-conversion

So in JRuby, this code might look like:

startGameButton.addListener {|event, x, y, pointer, button|
  game.setScreen( GameScreen.new(game) )
  true
}

Make sense?

It also lets you use snake_case instead of camelCase for those identifiers if you wish for things to look more ruby-like, and also has sugar for getters and setters. So I imaging you could write game.screen = GameScreen.new(game) instead of game.setScreen( GameScreen.new(game) )
