LibGDX ButtonGroupコントロールダウンできるボタンの数

Question

私はLibGDXに少し新しく、一度にどれだけ多くのボタンをダウン状態にすることができるのか不思議に思っていました。私がこれらのボタンで達成したいと思うのはこれです：私の指が1つに触れると、それは押され、一度に1つしか押せなくなり、そして私の指のうちの1つがそれを押すボタンにあり、もう1つのボタンを押すと、最初に押されたものが元の状態に戻り、もう一度押さえる唯一の方法は、私が指を離してもう一度押すことです。

とにかく、ここに私のコードです。どんな助けでも感謝します、ありがとう。

public MenuStateTest(GameStateManager gsm) { 
    super(gsm); 
    cam.setToOrtho(false, MyGame.WIDTH, MyGame.HEIGHT); 

    fitViewport = new FitViewport(MyGame.WIDTH, MyGame.HEIGHT); 

    stage = new Stage(fitViewport); 
    Gdx.input.setInputProcessor(stage); 
    font = new BitmapFont(); 
    skin = new Skin(); 

    buttonAtlas = new TextureAtlas("buttonTest.pack"); 
    skin.addRegions(buttonAtlas); 
    textButtonStyle = new TextButton.TextButtonStyle(); 
    textButtonStyle.font = font; 
    textButtonStyle.up = skin.getDrawable("1BBlock"); 
    textButtonStyle.down = skin.getDrawable("T1BBlock"); 
    button = new TextButton("", textButtonStyle); 
    stage.addActor(button); 
    button.setPosition(20, 200); 
    button.getStyle().checked = button.getStyle().down; 

    button2Atlas = new TextureAtlas("Button2Test.pack"); 
    skin.addRegions(button2Atlas); 
    textButtonStyle = new TextButton.TextButtonStyle(); 
    textButtonStyle.font = font; 
    textButtonStyle.up = skin.getDrawable("2BBlock"); 
    textButtonStyle.down = skin.getDrawable("T2BBlock"); 
    button2 = new TextButton("", textButtonStyle); 
    stage.addActor(button2); 
    button2.setPosition(175, 200); 
    button2.getStyle().checked = button2.getStyle().down; 

    button3Atlas = new TextureAtlas("Button3Test.pack"); 
    skin.addRegions(button3Atlas); 
    textButtonStyle = new TextButton.TextButtonStyle(); 
    textButtonStyle.font = font; 
    textButtonStyle.up = skin.getDrawable("3BBlock"); 
    textButtonStyle.down = skin.getDrawable("T3BBlock"); 
    button3 = new TextButton("", textButtonStyle); 
    stage.addActor(button3); 
    button3.setPosition(330, 200); 
    button3.getStyle().checked = button3.getStyle().down; 

    ButtonGroup buttons = new ButtonGroup(button1, button2, button3); 
    buttons.setMaxCheckCount(1); 
} 

@Override 
protected void handleInput() { 

} 

@Override 
protected void update(float dt) { 
    stage.getViewport().update(Gdx.graphics.getWidth(), Gdx.graphics.getHeight()); 
}
