list view item change color on click

Question

I have i listview with 24 text views in it(each one of them present one hour of the day). What i am trying to do is to change background color of the item that i clicked.

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view, int i, long l) {
                View v;
                v = parent.getChildAt(i);
                v.setBackgroundColor(Color.GREEN);

        }
    });

The problem is that when i click on a specific item not only bg color of one item is changed but also some other items change their colors.

i Know that

getChildAt()

does not always get the same fixed item. I want to know how that should be done so that only the item that is clicked change bg color.

EDIT: Thats the whole fragment class

public class GamesFragment extends Fragment  {
    //TopRatedFragment tf = new TopRatedFragment();

    List list = new ArrayList<Date>();
    public ArrayAdapter<String> adapter;
    SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
    View v;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        final View rootView = inflater.inflate(R.layout.fragment_games, container, false);
        final ListView listView = (ListView) rootView.findViewById(R.id.listView);

        for(int i = 0;i<24;i++){

            String date = Integer.toString(i) +":00";

            try{
            Date num = sdf.parse(date);
            SimpleDateFormat time = new SimpleDateFormat("HH:mm");

            list.add(time.format(num));
            }catch(ParseException e){
                e.printStackTrace();
            }

        }
        adapter = new ArrayAdapter<String>(this.getActivity(), R.layout.layout1,R.id.textView,list);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view, int i, long l) {
                View v;
                v = parent.getChildAt(i);
                v.setBackgroundColor(Color.GREEN);

            }
        });



        listView.setAdapter(adapter);
        return rootView;
    }


}
