Switching theme by button Codename One

I'm having issues when I change my theme, I have a default theme and a theme called Blue, I change to Blue by pressing a button then it's working good untill I get back to my main Menu then it changes back to my default theme by overriding my Blue theme. I want to avoid it.

This is my initVars:

protected void initVars(Resources res){
    Toolbar.setOnTopSideMenu(false);
}

This is my button to do the change:

@Override
protected void onMain_Button4Action(Component c, ActionEvent event) {
     UIManager.initNamedTheme("/theme", "Blue");
     Display.getInstance().getCurrent().refreshTheme();
}

And this is my button function to back to my main Menu:

back.addActionListener(new ActionListener() 
        {
            public void actionPerformed(ActionEvent ev) 
            {
                new StateMachine("/theme");
            }
        });

Should I set something in initVars or in my ActionListener to avoid overriding?

I would suggest staring over with a new project. You are using the old GUI builder which is deprecated.

Assuming both themes are in the main res file you don't need to do that. You just need a reference to the resource file which you can get in the old GUI builder using fetchResourceFile().

Hashtable themeData = theme.getTheme("Theme Name");
UIManager.getInstance().setThemeProps(themeData);
Display.getInstance().getCurrent().refreshTheme();
