试试这个：
final BooleanProperty spacePressed = new SimpleBooleanProperty(false);final BooleanProperty rightPressed = new SimpleBooleanProperty(false);final BooleanBinding spaceAndRightPressed = spacePressed.and(rightPressed);// How to respond to both keys pressed together:spaceAndRightPressed.addListener(new ChangeListener<Boolean>() { @Override public void changed(Observablevalue<Boolean> obs, Boolean werePressed, Boolean arePressed) { System.out.println("Space and right pressed together"); }});// Wire up properties to key events:scene.setonKeyPressed(new EventHandler<KeyEvent>() { @Override public void handle(KeyEvent ke) { if (ke.getCode() == KeyCode.SPACE) { spacePressed.set(true); } else if (ke.getCode() == KeyCode.RIGHT) { rightPressed.set(true); } }});scene.setonKeyReleased(new EventHandler<KeyEvent>() { @Override public void handle(KeyEvent ke) { if (ke.getCode() == KeyCode.SPACE) { spacePressed.set(false); } else if (ke.getCode() == KeyCode.RIGHT) { rightPressed.set(false); } }});
