You are not assigning value to the string array: use

servicesNameArray = getResources().getStringArray(R.array.servicesName);

and instead of :

 ServicesAdapter adapter = new ServicesAdapter(getContext(), servicesNameArray, serviceImages);

use the activity context:

ServicesAdapter adapter = new ServicesAdapter(this.getActivity(), servicesNameArray, serviceImages);

you need to notify you adapter about your data set size:

super(context, R.layout.services_layout, servicesNameArray); //change here

I think this issue cause you dont pass data in correct way

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view= inflater.inflate(R.layout.services_fragment, container, false);
Resources resources = getResources();
        servicesNameArray = resources.getStringArray(R.array.servicesName);
        listView = (ListView) view.findViewById(R.id.listView_services);
        ServicesAdapter adapter = new ServicesAdapter(getContext(), servicesNameArray, serviceImages);
        listView.setAdapter(adapter);

        return view;
    }
