                        JSONArray result = mainList.getJSONArray("data");
                        if (result.length() > 0) {
                            for (int i = 0; i < result.length(); i++) {
                                mainList = result.getJSONObject(i);
                                OrdersModel model = new OrdersModel();

                                model.YearID = mainList.getString("YearID");
                                model.session_title_en = mainList.getString("session_title_en");
                                model.sitting_date = mainList.getString("sitting_date");
                                model.proceeding_file = mainList.getString("proceeding_file");
                                myList.add(model);
                            }
                            mAdapter.notifyDataSetChanged();
                            progess.dismiss();
                        } else {
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            }, new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.d(TAG, "Error: " + error.getMessage());
                    progess.dismiss();
                }
            });
            Log.d("params", strReq.getUrl() + " and " + strReq.getBodyContentType() + " abd " + strReq.getBodyContentType());
            // Adding String request to request queue
            AppSingleton.getInstance(getApplicationContext()).addToRequestQueue(strReq, TAG);
        } else {
            Toast.makeText(getApplicationContext(), "Please check your Internet Connection", Toast.LENGTH_SHORT).show();
        }
    }

    //check internet connection
    public static boolean isNetworkStatusAvialable(Context context) {
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        if (connectivityManager != null) {
            NetworkInfo netInfos = connectivityManager.getActiveNetworkInfo();
            if (netInfos != null) {
                return netInfos.isConnected();
            }
        }
        return false;
    }
}

Here is my OrderList.java class where i am setting the text from OderModel.java

public class OrderList extends RecyclerView.Adapter<OrderList.MyViewHolder> {

    List<OrdersModel> list;
    Context c;

    public OrderList(List<OrdersModel> list, Context c) {

        this.list = list;
        this.c = c;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.orders_list, parent, false);

        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {

        OrdersModel movie = list.get(position);
        holder.name.setText(movie.gettitle_en());
        holder.type.setText(movie.getYearID());
        holder.session_title.setText((movie.getsession_title_en()));
        holder.sitting_date.setText(movie.getsitting_date());
    }


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

    public class MyViewHolder extends RecyclerView.ViewHolder {
        public TextView name, type , session_title , sitting_date , proceeding_file;
        public MyViewHolder(View view) {
            super(view);
            name = view.findViewById(R.id.name);
            type = view.findViewById(R.id.type);
            session_title = view.findViewById(R.id.session_title);
            sitting_date = view.findViewById(R.id.sitting_date);
        }
    }
}

And here is my OrderModel.java where i made getters and setter

public class OrdersModel {

    String title_en;
    String YearID;
    String session_title_en;
    String sitting_date;
    String proceeding_file;


    public String gettitle_en() {
        return title_en;
    }
    public void settitle_en(String title_en) {
        this.title_en = title_en;
    }


    public String getYearID() {
        return YearID;
    }
    public void setYearID(String YearID) {
        this.YearID = YearID;
    }


    public String getsession_title_en() {
        return session_title_en;
    }
    public void setsession_title_en(String session_title_en) {
        this.session_title_en = session_title_en;
    }


    public String getsitting_date() {
        return sitting_date;
    }
    public void setsitting_date(String session) {
        this.sitting_date = sitting_date;
    }


    public String getproceeding_file() {
        return proceeding_file;
    }
    public void setproceeding_file(String date) {
        this.proceeding_file = proceeding_file;
    }

    String file;
}

Initialize viewButton in ViewHolder.

public class MyViewHolder extends RecyclerView.ViewHolder {
    public TextView name, type , session_title , sitting_date , proceeding_file;
    public Button viewButton;

    public MyViewHolder(View view) {
        super(view);
        name = view.findViewById(R.id.name);
        type = view.findViewById(R.id.type);
        session_title = view.findViewById(R.id.session_title);
        sitting_date = view.findViewById(R.id.sitting_date);
        viewButton = view.findViewById(R.id.view_button);
    }
}

Then set onClickListener on viewButton and openPdf

@Override
public void onBindViewHolder(MyViewHolder holder, int position) {

    OrdersModel movie = list.get(position);
    holder.name.setText(movie.gettitle_en());
    holder.type.setText(movie.getYearID());
    holder.session_title.setText((movie.getsession_title_en()));
    holder.sitting_date.setText(movie.getsitting_date());

    holder.viewButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            openPdf(movie.getproceeding_file())
        }
    });
}

Suggestion: You should move your PdfViewer in another activity and redirect user to that activity when click viewButton.

where is openPdf() method ? – Fahad Jameel Oct 30 '19 at 07:12
You have to implement it according your requirements? What are you trying to do? you put PdfViewer inside listitem. How can you show pdf within this tiny space? Check my suggestion – Md. Asaduzzaman Oct 30 '19 at 07:14
Also I suggest you to use **shxdos** pdfviewer as it's support pdf from `URL`. Check: https://jitpack.io/p/shxdos/AndroidPdfViewer – Md. Asaduzzaman Oct 30 '19 at 07:18
i have a webview on this activity when the button is clicked it will navigate to webview to open pdf – Fahad Jameel Oct 30 '19 at 07:23
Is it same activity or different? Post that part also – Md. Asaduzzaman Oct 30 '19 at 07:24
it is the same activity orderofday and i have a webview in orderofday xml that is posted above – Fahad Jameel Oct 30 '19 at 07:29
kindly post a openPdf() method to open a pdf on webview and id of webview is @pdfView – Fahad Jameel Oct 30 '19 at 07:30
`orderlist.java` is an adapter, it contains RecyclerView items. How can you show PDF in this tiny space? – Md. Asaduzzaman Oct 30 '19 at 07:38
in RecyclerView items each item contain a pdf when an item is clicked it should open a pdf in webview. now you suggest me what to do im very worried :( – Fahad Jameel Oct 30 '19 at 07:47

initialise view_pdf button in MyViewHolder class. like others.
parse proceeding file like others ~ movie.getproceeding_file()

under the onBindViewHolder put below snippet of code:

  holder.proceeding_file.setOnClickListener(new View.OnClickListener() {

  @Override
  public void onClick(View view) {

        String pdf_url = movie.getproceeding_file();
        // do not forget to concate preceding url of the pdf
        Webview webView = (WebView) findViewById(R.id.webView1);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl(pdf_url);

      }
   });

I need to open a Pdf file when card view button clicked and each card has its own pdf against
