vi.setOnClickListener(new OnItemClickListener(position));
            final int pos = position;
            holder.button.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {

                    View parentView = (View) v.getParent();

                    int totAmount = Integer.parseInt(((TextView) parentView
                            .findViewById(R.id.text1)).getText()
                            .toString());

                    count = Integer.parseInt(((TextView) parentView
                            .findViewById(R.id.counter)).getText().toString());
                    count++;
                    tot_amt = totAmount * count;

                    ((TextView) parentView.findViewById(R.id.counter))
                            .setText(String.valueOf(count));

                    ((TextView) parentView.findViewById(R.id.totalPrice))
                            .setText(String.valueOf(tot_amt));

                    //Here I am saving the total amount and quantity
                    tempValues = null;
                    tempValues = (ListModel) data.get(pos);
                    tempValues.setProductName(tempValues.getProductName());
                    tempValues.setPrice(tempValues.getPrice());
                    tempValues.setImage(tempValues.getImage());
                    tempValues.setQuantity(String.valueOf(count));
                    tempValues.setTotalAmount(String.valueOf(tot_amt));
                    data.set(pos, tempValues);
                    ListViewExample sct = (ListViewExample) activity;
                    sct.getAllValues();
                }

            });

            holder.decreesButton2.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {

                    View parentView = (View) v.getParent();
                    int totAmount = Integer.parseInt(((TextView) parentView
                            .findViewById(R.id.text1)).getText()
                            .toString());

                    count = Integer.parseInt(((TextView) parentView
                            .findViewById(R.id.counter)).getText().toString());
                    if (count > 0) {
                        count--;

                        tot_amt = totAmount * count;

                        ((TextView) parentView.findViewById(R.id.totalPrice))
                                .setText(String.valueOf(tot_amt));
                        ((TextView) parentView.findViewById(R.id.counter))
                                .setText(String.valueOf(count));

                    //Here I am saving the total amount and quantity
                        tempValues = null;
                        tempValues = (ListModel) data.get(pos);
                        tempValues.setProductName(tempValues
                                .getProductName());
                        tempValues.setPrice(tempValues.getPrice());
                        tempValues.setImage(tempValues.getImage());
                        tempValues.setQuantity(String.valueOf(count));
                        tempValues.setTotalAmount(String.valueOf(tot_amt));
                        data.set(pos, tempValues);
                        ListViewExample sct = (ListViewExample) activity;
                        sct.getAllValues();
                    }
                }

            });
