Populate Recycler View with Api

1. Recycler View Adapter

public class ReceiptListAdapter extends RecyclerView.Adapter<ReceiptListAdapter.ReceiptListViewHolder> {

    // List<UserModel> list = new ArrayList<UserModel>();
    List<receipt> data;
    iItemClickListnerRK iItemClickListnerRk;

    public ReceiptListAdapter(List<receipt> data, iItemClickListnerRK iItemClickListnerRk) {
        this.data = data;
        this.iItemClickListnerRk = iItemClickListnerRk;
    }

    @Override
    public ReceiptListViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View view = inflater.inflate(R.layout.receipt_item_list, parent, false);
        return new ReceiptListViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ReceiptListViewHolder holder, int position) {
        String title = data.get(position).toString();
        holder.txtTitle.setText(title);

        holder.itemView.setOnClickListener(view -> {
            iItemClickListnerRk.onClickItemListnerRK(title, position);//this will get current index of item in recyclerView
        });
    }

    @Override
    public int getItemCount() {
        return data.size();
    }

    public interface iItemClickListnerRK {
        void onClickItemListnerRK(String itemNameRK, int idx);
    }


    public class ReceiptListViewHolder extends RecyclerView.ViewHolder {
        ImageView imgIcon;
        TextView txtTitle;

        public ReceiptListViewHolder(View itemView) {
            super(itemView);
            imgIcon = itemView.findViewById(R.id.imgIcon);
            txtTitle = itemView.findViewById(R.id.txtTitle);
        }
    }
}

2. Call Api

public class VolleyActions {

    Context context;
    ProgressBar progressBar;


    public VolleyActions(Context context, ProgressBar progressBar) {
        this.context = context;
        this.progressBar = progressBar;
    }   


    //get meter Json Object
    public interface IVolleyGet {
        void onError(String message);

        void onResponse(JSONObject jsonObject);
    }

    public void volleyGet(String appedUrl, String filters, IVolleyGet iVolleyGet) {


        Api_Urls api_urls = new Api_Urls();

        String getUrl = api_urls.API_URL + appedUrl + filters;

        RequestQueue requestQueue = Volley.newRequestQueue(context);

        //api key authentication
        session_rk sessionRk = new session_rk(context);
        String apiKey = sessionRk.f_api_key();
        //api key authentication


        //Start progress bar
        progressBar.setVisibility(View.VISIBLE);
        //Execute post request
        JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, getUrl, null, new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
//                System.out.println(response);
                progressBar.setVisibility(View.INVISIBLE);

                //JSONObject rdata;
                try {
                    Integer st = Integer.parseInt(response.getString("Item1").toString());
                    if (st.equals(200)) {
                        //rdata = response.getJSONObject("m_Item3");
                        iVolleyGet.onResponse(response);
                    } else {
                        Toast.makeText(context, "" + response.getString("Item2"), Toast.LENGTH_SHORT).show();
                    }
                } catch (JSONException e) {
                    Toast.makeText(context, "" + e.getMessage(), Toast.LENGTH_SHORT).show();
                    e.printStackTrace();
                }

            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Toast.makeText(context, "" + error.getMessage(), Toast.LENGTH_SHORT).show();
                error.printStackTrace();
                progressBar.setVisibility(View.INVISIBLE);
            }
        }) {
            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                Map<String, String> params = new HashMap<String, String>();
                params.put("Content-Type", "application/json");
                params.put("Authorization", "basic " + apiKey);

                return params;
            }
        };

        requestQueue.add(jsonObjectRequest);

    }
    //get meter Json Object e


}

3. Populate Recycler View with Model List

    public void f_show_list1() {

        List<receipt> lng = new ArrayList<receipt>();
        String filters = "?";
//        if (!etd_from.getText().toString().isEmpty() && !etd_to.getText().toString().isEmpty()) {
//            filters += "Date_From=" + etd_from.getText().toString() + "&";
//            filters += "Date_To=" + etd_to.getText().toString() + "&";
//        }
        userAcc user = (userAcc) spnr_pcode.getSelectedItem();
        if (!user.getLCode().isEmpty()) {
            filters += "Pcode=" + user.getLCode() + "&";
        }

        VolleyActions a = new VolleyActions(this, progressBar);
        a.volleyGet("receipt/data", filters, new VolleyActions.IVolleyGet() {
            @Override
            public void onError(String message) {
                Toast.makeText(receipt_list.this, "Invalid transaction.", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onResponse(JSONObject jsonObject) {
                try {
                    JSONArray jsonArray = jsonObject.getJSONArray("Item3");
                    for (int i = 0; i < jsonArray.length(); i++) {
                        JSONObject jObj = jsonArray.getJSONObject(i);
                        receipt obj = new receipt();
                        obj.setRec_No(jObj.getString("Rec_No"));
                        obj.setPName(jObj.getString("PName"));
                        obj.setRec_Date(jObj.getString("Rec_Date"));
                        obj.setAmt(Double.parseDouble(jObj.getString("Amt")));
                        lng.add(obj);
                    }

                    //recycler view
                    RecyclerView recyclerView1 = findViewById(R.id.rcyVw_receipt);
                    recyclerView1.setLayoutManager(new LinearLayoutManager(receipt_list.this));
                    ReceiptListAdapter recyclerAdapter1 = new ReceiptListAdapter(lng, new ReceiptListAdapter.iItemClickListnerRK() {
                        @Override
                        public void onClickItemListnerRK(String itemNameRK, int idx) {
                            Toast.makeText(receipt_list.this, "Clicked => P:" + idx + ", item:" + itemNameRK, Toast.LENGTH_SHORT).show();
                        }
                    });
                    recyclerView1.setAdapter(recyclerAdapter1);
                    //recycler view e


                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        });

        Toast.makeText(receipt_list.this, "Fetching...", Toast.LENGTH_SHORT).show();
    }
