如何从Libgdx动态调用重写暂停方法?

我创建了一个Libgdx游戏,我想知道是否可以使用Libgdx调用覆盖暂停方法生命周期?

下面是我的类中的暂停方法生命周期:

public class MyGdxGame extends ApplicationAdapter {
    @Override
    public void pause() {
        super.pause();
        chrono.pause();
        //Display a pause menu
    }
}

我想在单击暂停图像时调用生命周期方法:

    imagePause = new Image(new Texture(Gdx.files.internal("pause.png")));
    imagePause.setSize(pauseSize, pauseSize);
    imagePause.setPosition(width - pauseSize, height - pauseSize);
    imagePause.addListener(new ClickListener() {
        @Override
        public void clicked(InputEvent event, float x, float y) {
            //Something like this? :
            Gdx.app.pause(); //Doesn't exist

            //I don't want to call manually the pause method like this       
            //because it doesn't pause Libgdx lifecycle ...
            pause();
        }
    });
    stage.addActor(imagePause);

知道吗?
