List of Views in LinearLayout inside ScrollView

I'm trying to add two lists into a ScrollView and I've recently read that you shouldn't put ListViews inside a ScrollView. So I decided to try using two LinearLayouts and dynamically adding inflated views to them. Unfortunately all I'm seeing is the two text views I'm using as titles but no Linear Layouts. :/ Could someone please explain why my LinearLayouts are not not showing?

Layout Inflation:

ArrayList<JSONObject> sightList = new ArrayList<JSONObject>();
    try{
    JSONObject obj = new JSONObject(loadJSONFromAsset());
    JSONArray m_jArry = obj.getJSONArray("Locations");

    for (int i = 0; i < m_jArry.length(); i++) 
      {
       JSONObject jo_inside = m_jArry.getJSONObject(i);
       if ("Food & Drink".equals(jo_inside.getString("Section")))
       {
           sightList.add(jo_inside);
       }
      }
    }
    catch (Exception e) {}
    sort(sightList);

    LinearLayout discounts = (LinearLayout) findViewById(R.id.discount_list);
    LinearLayout others = (LinearLayout) findViewById(R.id.other_list);

    for (int i = 0; i < sightList.size(); i++)
    {
        JSONObject j = sightList.get(i);
        try {
            View v = getLayoutInflater().inflate(R.layout.next_list_item, null);
            v.setId(i);
            TextView title = (TextView) v.findViewById(R.id.title);
            TextView subtitle = (TextView) v.findViewById(R.id.subtitle);
            title.setText(j.getString("name"));
            title.setTypeface(montserrat);
            subtitle.setText(j.getString("TypeOfR"));
            subtitle.setTypeface(montserrat);

            if (j.getBoolean("hasDiscount"))
            {
                discounts.addView(v);
            }
            else
            {
                title.setTextColor(Color.BLACK);
                others.addView(v);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
