ImageButton and Preferences

Question

How can I create an ImageButton (musicButton) that control setting music on or off ?

I have GamePrefs class that has these 2 methods

public static void setBoolean(String name, boolean val) {
    prefs.setBoolean(name, val);
    prefs.flush();
}

public static boolean getBoolean(String name) {
    return prefs.getBoolean(name);
}

I have two images for the musicButton

Texture t1 = new Texture("music");
Texture t2 = new Texture("music_off");
TextureRegion tr1 = new TextureRegion(t1);
TextureRegion tr2 = new TextureRegion(t2);

I know I need to make an ImageButtonStyle but I have many fields imageUp, imageDown, checked, checkedOver... I don't know which two I should use

and I need it to respond to touch and changing current music setting to on or off

something like this :

GamePrefs.setBoolean("music", false) or GamePrefs.setBoolean("music", true)

and I will use getBoolean() to play music or not

Any help ?

Answer 1

For creating such kind of buttons I used ImageButton.ImageButtonStyle with up and checked attributes:

public Button getMusicButton() {
    final Button button = new ImageButton(getMusicButtonStyle());
    button.setChecked(Prefs.isMusicOn());
    button.addListener(new ClickListener(){
        @Override
        public void clicked(InputEvent event, float x, float y) {
            MusicHandler.getInstance().toggleMusic();
        }
    });
    return button;
}

private ImageButton.ImageButtonStyle getMusicButtonStyle() {
    ImageButton.ImageButtonStyle style = new ImageButton.ImageButtonStyle();
    style.up = musicOffDrawable;
    style.checked = musicOnDrawable;
    return style;
}

For music and sounds I have MusicHandler class with this method:

public void toggleMusic() {
    Prefs.toggleMusic();
    if (!Prefs.isMusicOn()) {
        music.stop();
    } else {
        music.play();
    }
}

And finally in Prefs class there are:

public static boolean isMusicOn() {
    return pref.getBoolean(MUSIC_ON);
}

public static void toggleMusic() {
    pref.putBoolean("music_on", !isMusicOn());
    pref.flush();
}
