Just Paste in Your Activity or Fragment

rvSelectedProductList = Recyclerview
selcetedItemAdapter = RecyclerView Adapter
              rvSelectedProductList.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
                    @Override
                    public void onGlobalLayout() {

                        final int itemCount = selectedItemAdapter.getItemCount();

                        for (int i = 0; i < itemCount; i++) {
                            TextView tvSelling = rvSelectedProductList.getChildAt(i).findViewById(R.id.tvSelling);
                            TextView textViewDrawerTitle = rvSelectedProductList.getChildAt(i).findViewById(R.id.tvCartQty);


                            String totalamount = tvSelling.getText().toString();
                            String qty = textViewDrawerTitle.getText().toString();
                            System.out.println("qty" + qty);
                            System.out.println("total" + totalamount);
                        }
                        rvSelectedProductList.getViewTreeObserver().removeGlobalOnLayoutListener(this);
                    }
                });
