Separating children from an expandable list

Question

I want to separate the children of the list so that I can assign different individual web links for each one, so far the expandable list generates all the children without a way to individually separate them so that each one could have its own web link. I'm new to android and I've only been doing this for a few months so could someone tell me how I can individually assign a web link to each child because right now every child from the list has the same link assigned to it. Child view of an expandable 2 level list:

public View getChildView(int i, int i1, boolean b, View view, ViewGroup viewGroup) {
        String childText = (String)getChild(i,i1);

        if (view == null)
        {
            LayoutInflater inflater = (LayoutInflater)this.context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
            view=inflater.inflate(R.layout.assessment_child_list, null);
        }
        TextView listC = (TextView)view.findViewById(R.id.listC);
        listC.setText(childText);

        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
 
                String url = "https://www.bbc.co.uk/bitesize?id=<package_name>";

                Intent i = new Intent(Intent.ACTION_VIEW);
                i.setData(Uri.parse(url));
                context.startActivity(i);
            }
        });
        return view;
    }

Populating the expandable list:

private void initData(){
        listP = new ArrayList<>();
        listC = new HashMap<>();

        listP.add("Week 1-2");
        listP.add("Week 3-4");
        listP.add("Week 5-6");
        listP.add("Week 7-8");
        listP.add("Week 9-10");
        listP.add("Week 11-12");

        List <String> wk1_2 = new ArrayList<>();
        wk1_2.add("BBC Bitesize");
        wk1_2.add("Google");

        List <String> wk3_4 = new ArrayList<>();
        wk3_4.add("BBC Bitesize");

        List <String> wk5_6 = new ArrayList<>();
        wk5_6.add("BBC Bitesize");

        List <String> wk7_8 = new ArrayList<>();
        wk7_8.add("BBC Bitesize");

        List <String> wk9_10 = new ArrayList<>();
        wk9_10.add("BBC Bitesize");

        List <String> wk11_12 = new ArrayList<>();
        wk11_12.add("BBC Bitesize");


        listC.put(listP.get(0),wk1_2);
        listC.put(listP.get(1),wk3_4);
        listC.put(listP.get(2),wk5_6);
        listC.put(listP.get(3),wk7_8);
        listC.put(listP.get(4),wk9_10);
        listC.put(listP.get(5),wk11_12);
    }
