Change CreateOrderView as below,

class CreateOrderView(generics.CreateAPIView):
    serializer_class = OrderCreateSerializer

    def perform_create(self, serializer):
        return serializer.save(user=self.request.user)

    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        instance = self.perform_create(serializer)
        instance_serializer = OrderListSerializer(instance)
        return Response(instance_serializer.data)

serializer.save() returns the instance that just created or updated. So we use that istance to pass to the OrderListSerializer and returning the corresponding response.

You could overwrite create(), and return whatever you want:

from rest_framework import response, status
(...)
    def create(self, request, *args, **kwargs):
        super().create(request, *args, **kwargs)
        return response.Response(status=status.HTTP_201_CREATED)
(...)

There are several ways you can use here. First,

class CreateOrderView(generics.ListCreateAPIView):
    serializer_class = OrderCreateSerializer

    def perform_create(self, serializer):
        serializer.save(user=self.request.user)

    def list(self, *args, **kwargs):
        serializer_class = OrderListSerializer
        serializer = serializer_class(self.get_queryset())
        return Response(serializer.data)

The alternative would be a conditional if statement, where 

if self.request.method=='POST':
   self.serializer_class = OrderCreateSerializer
elif self.request.method=='GET':
   self.serializer_class = OrderListSerializer
