How to make nav drawer item background color span the whole drawer and become unclickable?

Question

Below is a screenshot and files for my nav drawer. Currently, the yellow background on "Features - Day of Event" and the others only spans the title when it should span the entire nav drawer view with the text left-aligned instead of in line with the other items. Also, the items with the yellow background are clickable and although they don't go anywhere, they close the nav bar when they shouldn't. I apologize in advance as I've inherited this project from someone else and have no prior experience with android studio. Thank you!

MainActivity.java snippet; this is where the nav drawer items seem to get their color:

Menu menu = navigationView.getMenu();
    MenuItem features= menu.findItem(R.id.features);
    SpannableString s = new SpannableString(features.getTitle());
    s.setSpan(new BackgroundColorSpan(Color.parseColor("#FDDA24")), 0, s.length(), 0);
    s.setSpan(new ForegroundColorSpan(Color.parseColor("#ffffff")), 0, s.length(), 0);
    s.setSpan(new RelativeSizeSpan(1.5f), 0, s.length(), 0);
    features.setTitle(s);

    Menu menu1 = navigationView.getMenu();
    MenuItem social_media= menu1.findItem(R.id.social_media);
    SpannableString t = new SpannableString(social_media.getTitle());
    t.setSpan(new BackgroundColorSpan(Color.parseColor("#FDDA24")), 0, t.length(), 0);
    t.setSpan(new ForegroundColorSpan(Color.parseColor("#ffffff")), 0, t.length(), 0);
    t.setSpan(new RelativeSizeSpan(1.5f), 0, t.length(), 0);
    social_media.setTitle(t);

    MenuItem app_guide= menu.findItem(R.id.app_guide);
    SpannableString u = new SpannableString(app_guide.getTitle());
    u.setSpan(new BackgroundColorSpan(Color.parseColor("#FDDA24")), 0, u.length(), 0);
    u.setSpan(new ForegroundColorSpan(Color.parseColor("#ffffff")), 0, u.length(), 0);
    u.setSpan(new RelativeSizeSpan(1.5f), 0, u.length(), 0);
    app_guide.setTitle(u);
