Answer 1

The above solutions are all hard coded in the xml.

There is an alternative solution which allows you to change it programmatically. https://stackoverflow.com/a/11494962/5089713 Once you have the TextView, you can do whatever with it, for instance change the font size.

your code then looks like

Spinner food = (Spinner) findViewById(R.id.spinner1);

CharSequence[] strings = getActivity().getResources().getTextArray(R.array.item_array);
    ArrayAdapter foodadapter = new ArrayAdapter(getActivity(), android.R.layout.simple_spinner_item, strings){
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View view =super.getView(position, convertView, parent);
            TextView textView=(TextView) view.findViewById(android.R.id.text1);
            // do whatever you want with this text view
            textView.setTextSize(20);
            return view;
        }
    };

foodadapter.setDropDownViewResource(android.R.layout.simple_spinner_item);        
food.setAdapter(foodadapter);
