Make one button do two different things

Question

What Im trying to implement is to have one of my buttons draw an image on the screen on click, but then I need to same button to dispose()/clear() the image when pressed again! I´ve managed this before, but I can´t remember how it´s done.

btnShare.addListener(new ChangeListener() {
            @Override
            public void changed(ChangeEvent event, Actor actor) {

                stage.addActor(btnFB);
            }
        });

You can check if the button was clicked by setting a certain Boolean clicked = false; to true and false like this:

yourButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            if(clicked) {
                clear();
                clicked = false;
            }
            else {
                draw();
                clicked = true;
            }

        }
    });
