How to charge for shipping?

Question

Java

Tell me how, in the onItemSelected() method, when selecting an item from the spinner, if the value "Pickup" matches, for example, add the amount for delivery, let's say 350, and display this markup in the getDataFromDatabase() method

public class ActivityCheckout extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_checkout);
        view = findViewById(android.R.id.content);

        if (Config.ENABLE_RTL_MODE) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
                getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
            }
        }

        sharedPref = new SharedPref(this);

        setupToolbar();
        getSpinnerData();
        getTaxCurrency();

        dbhelper = new DBHelper(this);
        try {
            dbhelper.openDataBase();
        } catch (SQLException sqle) {
            throw sqle;
        }

        // Creating Volley newRequestQueue
        requestQueue = Volley.newRequestQueue(ActivityCheckout.this);
        progressDialog = new ProgressDialog(ActivityCheckout.this);

        btn_submit_order = findViewById(R.id.btn_submit_order);

        edt_name = findViewById(R.id.edt_name);
        edt_email = findViewById(R.id.edt_email);
        edt_phone = findViewById(R.id.edt_phone);
        edt_address = findViewById(R.id.edt_address);
        edt_shipping = findViewById(R.id.edt_shipping);
        edt_order_list = findViewById(R.id.edt_order_list);
        edt_order_total = findViewById(R.id.edt_order_total);
        edt_comment = findViewById(R.id.edt_comment);

        edt_order_list.setEnabled(false);

        getDataFromDatabase();
        submitOrder();

    }

    private void getShipping(JSONArray jsonArray) {
        for (int i = 0; i < jsonArray.length(); i++) {
            try {
                JSONObject json = jsonArray.getJSONObject(i);
                arrayList.add(json.getString("shipping_name"));
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }

        ArrayAdapter<String> myAdapter = new ArrayAdapter<String>(ActivityCheckout.this, R.layout.spinner_item, arrayList);
        myAdapter.setDropDownViewResource(R.layout.spinner_dropdown_item);
        spinner.setAdapter(myAdapter);
    }

    private String setShipping(int position) {
        String name = "";
        try {
            JSONObject json = result.getJSONObject(position);
            name = json.getString("shipping_name");

Answer 1

By simply adding the amount for delivery to the database, get it in And add it to the formula that calculates the delivery
getParams()
params.put("comis", str_comis);
