我想在底部标签的顶部添加该行，如何添加？像这个问题https://github.com/react-navigation/react-navigation/issues/8957

反应导航版本：

  public class MenuCardFragment extends Fragment {
    ...
    
       protected void onBindViewHolder(@NonNull final MenuCardFragment.ItemViewHolder itemViewHolder, int position, @NonNull final Items item) {
    
                    String categorie = getArguments().getString("categorie");
                    final String foodType = item.getFoodType();
    
                    if (shop_type == null) {
                        shop_type = "Shop";
                    }
    
                    final String itemName = item.getItemName();
                    final String itemPrice = item.getItemPrice();
                    final String itemType = item.getItemType();
                    final String btw = item.getBtw_tarif();
    
                    if (itemPrice.equals("sub")) {
                        itemViewHolder.makeSubCategoryRow(itemName);
                        itemViewHolder.mView.findViewById(R.id.subcategory_row_text).setVisibility(View.VISIBLE);
                        itemViewHolder.mView.findViewById(R.id.item_sub).setVisibility(View.GONE);
                        itemViewHolder.mView.findViewById(R.id.item_single_amount).setVisibility(View.GONE);
                        itemViewHolder.mView.findViewById(R.id.single_display_nr).setVisibility(View.GONE);
                        itemViewHolder.mView.findViewById(R.id.item_display_single_name).setVisibility(View.GONE);
                        itemViewHolder.mView.findViewById(R.id.item_single_amount).setVisibility(View.GONE);
                        itemViewHolder.mView.findViewById(R.id.item_display_single_price).setVisibility(View.GONE);
                        return;
                    }
                   itemViewHolder.mView.findViewById(R.id.subcategory_row_text).setVisibility(View.GONE);
    
                    final Communicator communicator = (Communicator)getActivity();
                    itemViewHolder.setRowNumber(position);
                    itemViewHolder.setItemName(itemName);
                    itemViewHolder.setItemPrice(itemPrice);
    
                    itemViewHolder.mView.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            communicator.sendToBill(itemName, itemPrice, foodType, itemType, btw);
                            itemViewHolder.updateAmountField();
    
                        }
                    });
                    itemViewHolder.mView.findViewById(R.id.item_sub).setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            itemViewHolder.updateAmountFieldForRemove();
                        }
                    });
                }
            };
    
    
    }

您可以使用如下所示的自定义按钮

并在初始化导航时将其提供为tabBarButton。

const CustomTabButton = (props) => (
  <TouchableOpacity
    {...props}
    style={
      props.accessibilityState.selected
        ? [props.style, { borderTopColor: 'red', borderTopWidth: 2 }]
        : props.style
    }
  />
);
