Recyclerview прокручивает верх, когда я добавляю кол-во в тексте редактирования последней позиции

Question

private void showDialogForQtychange (int position, String productId, String qty) {LayoutInflater li = LayoutInflater.from (mContext); @SuppressLint ("InflateParams"). Представление promptsView = li.inflate (R.layout.dialog_qty_chnage, null); AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder (mContext); alertDialogBuilder.setTitle (getString (R.string.select_qty));

    final EditText userInput = promptsView.findViewById(R.id.etQty);
    alertDialogBuilder
            .setCancelable(false)
            .setPositiveButton(getString(R.string.str_ok),
                    (dialog, id) -> {

              mProductCartInfos.get(position).setQty(userInput.getText().toString().trim());
                        requestToAddProductTocart(productId, userInput.getText().toString().trim());
                    })
            .setNegativeButton(getString(R.string.str_cancel),
                    (dialog, id) -> dialog.cancel());

    AlertDialog alertDialog = alertDialogBuilder.create();
    alertDialog.show();
}
