    private ListView simpleList;


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_cherche, container,
                false);
        simpleList= rootView.findViewById(R.id.ListC);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
                android.R.layout.simple_list_item_1, countryList);
        simpleList.setAdapter(adapter);


        simpleList.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1,
                                    int position, long arg3) {
                Toast.makeText(getContext(), position, Toast.LENGTH_SHORT).show();



            }
        });

        return rootView;
    }


}

CommonsWare :

Replace:

Toast.makeText(getContext(), position, Toast.LENGTH_SHORT).show()

with:

Toast.makeText(getContext(), Integer.toString(position), Toast.LENGTH_SHORT).show()

The version of makeText() that takes an int as the second parameter is expecting that int to be a string resource ID. Yours is not. So, you need to convert position to a String yourself.
