Values from RecyclerView in email Intent

[Carel Venter]

Hi all. I'm quite new to Java, as you can see if you look at some of my code..lol. Last bit of my project and I'm stuck. I have a custom adapter with a recycler view. There are some text views. I also have a bottom menu with an email button and I would like to use 2 of the views (R.id.brand_name & R.id.cases_text_view) and sent them as text in an email. The whole email intent and bottom menu is working fine, but I can’t get the two values to be added to the EXTRA_TEXT part of the intent (line 51 and 52). I would really appreciate some help.

Here is the activity with the intent and bottom menu:

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.order_by_brand);
        setTitle("Black Label");

        recyclerView = (RecyclerView) findViewById(R.id.recycler);

        modelArrayList = getModel();
        customAdapter = new CustomAdapter(this);
        recyclerView.setAdapter(customAdapter);
        recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.VERTICAL, false));
    }
    private ArrayList<Model> getModel() {
        final ArrayList<Model> list = new ArrayList<>();
        for (int i = 0; i < 8; i++) {

            final Model model = new Model();
            model.setNumber(0);
            model.setNumber2(0);
            model.setImage(myimage[i]);
            model.setBrand(brandlist[i]);
            model.setPallet_size(pallet_size[i]);
            list.add(model);

        BottomNavigationView bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottomNavView_Bar);
        BottomNavigationViewHelper.disableShiftMode(bottomNavigationView);
        Menu menu = bottomNavigationView.getMenu();
        MenuItem menuItem = menu.getItem(0);
        menuItem.setChecked(true);

        bottomNavigationView.setOnNavigationItemSelectedListener(

                new BottomNavigationView.OnNavigationItemSelectedListener() {
                    @Override
                    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                        switch (item.getItemId()) {
                            case R.id.ic_home:
                                Intent intent1 = new Intent(BlackLabel.this, MainActivity.class);
                                startActivity(intent1);
                                break;

                            case R.id.ic_clear:
                                Intent intent2 = new Intent(BlackLabel.this, BlackLabel.class);
                                startActivity(intent2);
                                break;

                            case R.id.ic_email:
                                Intent intent = new Intent(Intent.ACTION_SENDTO);
                                intent.setData(Uri.parse("mailto:[e-mail]"));
                                intent.putExtra(Intent.EXTRA_SUBJECT, "Please place order for....");
                                intent.putExtra(Intent.EXTRA_TEXT, R.id.brand_name);
                                intent.putExtra(Intent.EXTRA_TEXT, R.id.cases_text_view);
                                if (intent.resolveActivity(getPackageManager()) != null) {
                                    startActivity(intent);
                                }
                        }

                        return false;
                    }

                });
    }
   return list;
}}

And here is the recyclerview (I want to use the values in line 46 and 48):

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

    private LayoutInflater inflater;
    private Context ctx;

    public CustomAdapter(Context ctx) {

        inflater = LayoutInflater.from(ctx);
        this.ctx = ctx;
    }

    @Override
    public CustomAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = inflater.inflate(R.layout.rv_item, parent, false);
        MyViewHolder holder = new MyViewHolder(view);

        return holder;
    }

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

        holder.tvBrand.setText((CharSequence) modelArrayList.get(position).getBrand());
        holder.tvImage.setImageResource(Integer.parseInt(String.valueOf(modelArrayList.get(position).getImage())));
        holder.tvCases.setText(String.valueOf(modelArrayList.get(position).getNumber()));
        holder.tvPallet_size.setText(String.valueOf(modelArrayList.get(position).getPallet_size()));
        holder.tvCases.setText(String.valueOf(modelArrayList.get(position).getNumber2()));
        holder.tvPallets.setText(String.valueOf(modelArrayList.get(position).getNumber()));
        holder.tvCases.setText(String.valueOf(modelArrayList.get(position).getNumber2()));
    }

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

    class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

        protected Button btn_cases_plus, btn_cases_minus, btn_pallets_plus, btn_pallets_minus;
        protected ImageView tvImage;
        private TextView tvBrand, tvCases,tvPallets, tvPallet_size;

        public MyViewHolder(View itemView) {
            super(itemView);

            tvBrand = (TextView) itemView.findViewById(R.id.brand_name);

            btn_pallets_plus.setOnClickListener(this);
            btn_pallets_minus.setOnClickListener(this);
        }

        // onClick Listener for view
        @Override
        public void onClick(View v) {

                int number = Integer.parseInt(tvCases.getText().toString()) + 1;

                TextView tvCases = (TextView) tempview.findViewById(R.id.cases_text_view);
                int number = Integer.parseInt(tvCases.getText().toString()) - 1;
                if (number == 0 || number <0) {
                    Toast.makeText(ctx,"You cannot order less than one case", Toast.LENGTH_SHORT).show();
                    tvCases.setText(String.valueOf(0));
                    return;
                }
                tvCases.setText(String.valueOf(number));
                modelArrayList.get(getAdapterPosition()).setNumber(number);

            }  else if(v.getId() == btn_pallets_plus.getId()) {

                int number2 = Integer.parseInt(tvPallets.getText().toString()) * Integer.parseInt(tvPallet_size.getText().toString());
                tvCases.setText(String.valueOf(number2));
                modelArrayList.get(getAdapterPosition()).setNumber(number);
                modelArrayList.get(getAdapterPosition()).setNumber2(number2);

            }   else {

                    View tempview = (View) btn_pallets_minus.getTag(R.integer.btn_pallets_minus_view);
                    TextView tvPallets = (TextView) tempview.findViewById(R.id.pallets_text_view);

                    modelArrayList.get(getAdapterPosition()).setNumber2(number2);
                } } }
            }
        }

I know its probably very simple, but I just cant seem to figure it out.

You wish to send the values entered by user in those two fields, right?

[Carel Venter]

Hi there. yes that is exactly what I want to do. I want to use two values in an email intent as EXTRA_TEXT. (lines 51 and 52 on the main activity). The values must come from my adapter
lines 46

tvBrand = (TextView) itemView.findViewById(R.id.brand_name);

and 48

tvCases = (TextView) itemView.findViewById(R.id.cases_text_view);

The first one never changes (tvBrand), but the second one (tvCases) is being changed by the user with + and - buttons.  
Hope those are the ones I must use, on the MyViewHolder method.
After that the order must be emailed if the user clicks on the email in the bottom navigation menu.
Thank you very much for your interest so far, and you help will be appreciated.

Ok so I'm trying this:

        public void submitOrder(View view) {
            EditText textName = (EditText) findViewById(R.id.brand_name);
            String naam = textName.getText().toString();
            EditText textQuant = (EditText) findViewByID(R.id.cases_text_view);
            String hoeveel = textQuant.getText().toString();

            String orderMessage = createOrderSummary(naam, hoeveel);
        }
        private String createOrderSummary(String naam, String hoeveel) {
            String orderMessage = "Brand" + naam;
            orderMessage += "Quantity" + hoeveel;
            return orderMessage;
        }

Just after line 65 in the Adapter. But I get "Cannot resolve method 'findViewbyId(int)'. So that's problem one, second I get the same message if I want to call it in the mainActivity
in the intent

intent.putExtra(Intent.EXTRA_TEXT, orderMessage);

So I still have a little problem to call the values from the adapter to the mainActivity into EXTRA_TEXT in the email intent.
Some help would really be appreciated. Thank you
