transform() or override() or centerCrop() not working with glide Android

Question

This app currently is working perfectly fetches and displays images but when I try to add additional methods to glide in the ImageListAdapter class like override() or centerCrop() or transform() or placeholder(), it doesn't work. I mean it doesn't even let me add those, it shows in red and no similar suggestion but many tutorials suggest to use those methods to modify size, why does it not work. Am I doing something wrong?

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         String[] eatFoodyImages = {
