How to set two arraylist with different size inside one adapter?

Question

I have two arraylist which i use for storing value from JSON which have different path database. I want populate it with one custom adapter with this such way

1. First arraylist contain 2 name_stage and second arraylist contain 4 revenue and name_stage.
2. For second arraylist, i need loop for sum revenue and count data if name_stage is same.
3. One row will contain name_stage, result of sum revenue, and count data
4. First arraylist size will used for inflate row

This my JSON structure with dummy data

First JSON

{"result":[
  {"id":1,
   "name_stage":"New"},
  {"id":2,
   "name_stage":"Closing"}
  ]
 }

Second JSON

{"result":[
  {"id":1,
   "name_stage":"New",
   "revenue":3000},
  {"id":2,
   "name_stage":"Closing",
   "revenue":10000},
  {"id":3,
   "name_stage":"New",
   "revenue":2000},
  {"id":4,
   "name_stage":"Closing",
   "revenue":5000}
  ]
 }

I found similar case in this but i cant still figure this in my case

I try for parsing JSON and looping that (for second arraylist)

            detail = new HashMap<>();
            detail = new Gson().fromJson(_response, new TypeToken<HashMap<String, Object>>(){}.getType());
            str= (new Gson()).toJson(detail.get("result"), new TypeToken<ArrayList<HashMap<String, Object>>>(){}.getType());
            listmap_detail = new Gson().fromJson(str, new TypeToken<ArrayList<HashMap<String, Object>>>(){}.getType());
            for (int i=0;i<listmap_detail.size();i++){
             if(listmap_detail.get(a).get("stage_id").toString().equals("New")){
                    count_new+=1;                      
             new_revenue+=Double.parseDouble(listmap_detail.get(a).get("revenue").toString());
               }else if(listmap_detail.get(a).get("name_stage").toString().equals("Closing")){
                    count_closing+=1;       closing_revenue+=Double.parseDouble(listmap_detail.get(a).get("revenue").toString());
                }
            }

after that i try for passing it with intent and use that inside adapter like this

     Intent i = new Intent();
     i.setClass(this, NextActivity.class);
     i.putExtra("new_revenue", new_revenue);
     i.putExtra("closing_revenue", closing_revenue);
     i.putExtra("new_count", count_new);
     i.putExtra("closing_count", count_closing);
     startActivity(i);

Adapter in NextActivity

@Override
    public View getView(final int _position, View _v, ViewGroup _container) {
        LayoutInflater _inflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View _view = _v;
        if (_view == null) {
            _view = _inflater.inflate(R.layout.c_opportunity_stage, null);
        }
        final TextView t_stagenumber = (TextView) _view.findViewById(R.id.c_stagecount);
        final TextView t_stage = (TextView) _view.findViewById(R.id.c_stage);
        final TextView t_countstage = (TextView) _view.findViewById(R.id.c_countstage);
        final TextView t_revenue = (TextView) _view.findViewById(R.id.c_totalrevenue);

        t_stagenumber.setText(String.valueOf((long)(_position + 1)).concat("."));
        t_stage.setText(_data.get(_position).get("name_stage").toString());
        if (_data.get(_position).get("name_stage").toString().equals("New")){
            count = Double.valueOf(getIntent().getStringExtra("new_count"));
            t_countstage.setText(String.valueOf(count));

            str2 = getIntent().getStringExtra("new_revenue");
            dataresult = Double.parseDouble(str2);
            tampung = new Double(str2);
            bagi = tampung.intValue();
            a = 0;
            while (bagi!=0){
                bagi/=10;
                ++a;
            }

            if (a>=5&&a<7){
                dataresult/=Double.valueOf(1000);
                value = String.valueOf(dataresult);
                t_revenue.setText(value+" "+"K");
            }
            if (a>=7){
                dataresult/=Double.valueOf(1000000);
                value = String.valueOf(dataresult);
                t_revenue.setText(value+" "+"M");
            }
            if (a==0){
                t_revenue.setText("0");
            }
        }else if (_data.get(_position).get("name_stage").toString().equals("Closing")){
            count = Double.valueOf(getIntent().getStringExtra("closing_count"));
            t_countstage.setText(String.valueOf(count));

            str2 = getIntent().getStringExtra("closing_revenue");
            dataresult = Double.parseDouble(str2);
            tampung = new Double(str2);
            bagi = tampung.intValue();
            a = 0;
            while (bagi!=0){
                bagi/=10;
                ++a;
            }

            if (a>=5&&a<7){
                dataresult/=Double.valueOf(1000);
                value = String.valueOf(dataresult);
                t_revenue.setText(value+" "+"K");
            }
            if (a>=7){
                dataresult/=Double.valueOf(1000000);
                value = String.valueOf(dataresult);
                t_revenue.setText(value+" "+"M");
            }
            if (a==0){
                t_revenue.setText("0");
            }
        }
     }

This way already works but this bad way and will make my adapter error if intent value equals null. Can some guide me for this problem?
