需要获取所有Pickup Latitude Longitude并在地图上放置标记。谁能帮我这个？我能够获取所有数据并在活动中查看它。但我无法在地图上添加标记。）

private ArrayList<CustomerRequestList> dataList;
   Activity thisActivity;
   Context context;
   ApiInterface apiInterface = ApiClient.getRetrofit().create(ApiInterface.class);

    public CustomerListAdapter(ArrayList<CustomerRequestList> dataList) {
        this.dataList = dataList;
    }

    @Override
    public CustomerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
        View view = layoutInflater.inflate(R.layout.activity_driver_request_list, parent, false);
        return new CustomerViewHolder(view);   
    }

    @Override
    public void onBindViewHolder(CustomerViewHolder holder, int position) {                    holder.txtCusName.setText(dataList.get(position).getCustomerName());
        holder.txtCusPhon.setText(dataList.get(position).getPhonenumber()); 
        holder.txtCusFrom.setText(dataList.get(position).getFromLoc());
        holder.txtCusTo.setText(dataList.get(position).getToLoc());    
        String FromLat = dataList.get(position).getPickupLat();
        String FromLng = dataList.get(position).getPickupLng();
        String DropLat = dataList.get(position).getDropLat();
        String DropLng = dataList.get(position).getDropLng();            
        Utilities.printV("CustomerLoginResponse===>", FromLat);
        Utilities.printV("CustomerLoginResponse===>", FromLng);
        Utilities.printV("CustomerLoginResponse===>", DropLat);
        Utilities.printV("CustomerLoginResponse===>", DropLng);  
    }

    @Override
    public int getItemCount() {
        return dataList.size();
    }

    class CustomerViewHolder extends RecyclerView.ViewHolder {

        TextView txtCusName, txtCusFrom, txtCusPhon, txtCusTo;

        CustomerViewHolder(View itemView) {
            super(itemView);
            txtCusName = itemView.findViewById(R.id.txt_Customer_Name);
            txtCusPhon = itemView.findViewById(R.id.Customer_phonenumber);
            txtCusFrom = itemView.findViewById(R.id.Customer_PickLocation);
            txtCusTo = itemView.findViewById(R.id.Customer_DropLocation);
        }
    }

（请帮我在地图上添加多个标记以获取所有json数据）
