LibGdx ImageButton播放声音(LibGdx ImageButton playing sound)

 我用三个可绘制的图像创建了一个imageButton; 一个是按钮，一个按钮和一个按钮，其目的是为了开启和关闭游戏声音。一旦声音关闭，应该显示选中的图像。 
 
 我写过这样的代码： 
 
soundButton = new ImageButton(new TextureRegionDrawable(soundTexture1),
            new TextureRegionDrawable(soundTexture2), new TextureRegionDrawable(soundTexture3));
    stage.addActor(soundButton);

    soundButton.setPosition(Constants.WORLD_WIDTH / 4 + 300f, Constants.WORLD_HEIGHT / 4, Align.bottomLeft);
soundButton.addListener(new ChangeListener(){
        @Override
        public void changed(ChangeEvent event, Actor actor) {
            if(!game.soundBool)
                game.soundBool=true;
                else
                    game.soundBool=false;
        }
    });
 
 这里的soundBool最初是假的，游戏声音在假时会播放。 一旦我确实如此，声音就不应该发挥。这个布尔运行良好。 
 
 问题是，一旦我检查了按钮（声音关闭），声音就会永久关闭。按钮点击未按预期工作。 
 
 我如何更改代码以便更好地工作？ 

I have created an imageButton with three drawable images; one is button-up,button-down and button checked.Its purpose is to ON and OFF sound for the game.once sound is OFF,checked image should be displayed.
 
I have written the code like this:
 
soundButton = new ImageButton(new TextureRegionDrawable(soundTexture1),
            new TextureRegionDrawable(soundTexture2), new TextureRegionDrawable(soundTexture3));
    stage.addActor(soundButton);

    soundButton.setPosition(Constants.WORLD_WIDTH / 4 + 300f, Constants.WORLD_HEIGHT / 4, Align.bottomLeft);
soundButton.addListener(new ChangeListener(){
        @Override
        public void changed(ChangeEvent event, Actor actor) {
            if(!game.soundBool)
                game.soundBool=true;
                else
                    game.soundBool=false;
        }
    });
 
Here soundBool is initially false and game sounds will play when it is false. once I make it true,sounds should not play.This boolean is working well.
 
Problem is that once I checked the button(sound OFF) sound is getting OFF permanantly.Again Button click is not working as expected.
 
How do I change the code to work it well?
