How to retrive Images from firestore to recyclerview

I am trying to retrieve images from Firebase Firestore. I am able to retrieve text in RecyclerView successfully however I'm not sure how to retrieve the images.
I had a look at similar questions unfortunately none helped.

public ImageView getProductImage() {

}
public void setProductImage(ImageView productImage) {
ProductImage = productImage;
}
}
Here is the structure of my database

Follow these steps to show images in RecyclerView
Remove ImageView from ProductModel
Add String imageUrl to ProductModel and set its value with the image URL from Firestore (I see from the screenshot that it is named "Image").
In onBindViewHolder from the ProductAdapter, use the position provided to retrieve the appropriate ProductModel from productModelArrayList and pass its imageUrl value to ProductViewHolder.
In ProductViewHolder, use the imageUrl to load the image into the ImageView. (Glide and Picasso are two commonly used library to load images)
PS: Never add UI elements in your model. It will cause lifecycle issues in the future.
Let me know if you have any questions.

Firestore reference in android studio

I'm having some issues referencing a particular collection that is nested (I think that the term) I have attached an image of my database structure below:
EDIT: image of Foods collection
I basically have multiple documents that have a collection within them with the same name. Is there a way I can dynamically select the "Foods" collection depending on the restaurant ID that a user has clicked on the previous page. ie if the user selects a restaurant with ID 01, it should Load "Foods" from a document with ID 01, etc.
here is my code for the fragment loading the foods:
import android.content.Context;
import android.net.Uri;
import android.os.Bundle;
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.example.hostapp.Adapters.FoodAdapter;
import com.example.hostapp.Models.FoodModel;
import com.example.hostapp.R;
import com.firebase.ui.firestore.FirestoreRecyclerOptions;
import com.google.firebase.firestore.CollectionReference;
import com.google.firebase.firestore.FirebaseFirestore;
import com.google.firebase.firestore.Query;
public class MainsFragment extends Fragment {
private FirebaseFirestore db = FirebaseFirestore.getInstance();
private CollectionReference menuref = db.collection("Foods");
private FoodAdapter adapter;
String restaurantid = "";
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_mains, container, false);
Query query = menuref.whereEqualTo("menuid", restaurantid).orderBy("name");
FirestoreRecyclerOptions<FoodModel> options = new FirestoreRecyclerOptions.Builder<FoodModel>().
setQuery(query, FoodModel.class)
.build();
adapter = new FoodAdapter(options);
RecyclerView recyclerView = view.findViewById(R.id.recycler_mains);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this.getActivity()));
recyclerView.setAdapter(adapter);
return view;
}
private void setUpRecyclerView() {
}
#Override
public void onStart() {
super.onStart();
adapter.startListening();
}
#Override
public void onStop() {
super.onStop();
adapter.stopListening();
}
}
for the previous page on click:
import androidx.appcompat.app.AppCompatActivity;

setUpRecyclerView();
}
private void setUpRecyclerView(){
//Get intent
if(getIntent() != null)
categoryid = getIntent().getStringExtra("categoryid");
if(!categoryid.isEmpty() && categoryid != null)
{
Query query = restaurantref.whereEqualTo("categoryid", categoryid).orderBy("name");
final FirestoreRecyclerOptions<Restaurant> options = new FirestoreRecyclerOptions.Builder<Restaurant>().setQuery(query, Restaurant.class).build();
adapter = new RestaurantAdapter(options);
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.restaurant_recycler);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(adapter);
adapter.setOnItemClickListerner(new RestaurantAdapter.OnItemClickListener() {
#Override
public void onItemClick(DocumentSnapshot documentSnapshot, int position) {
Restaurant restaurant = documentSnapshot.toObject(Restaurant.class);
Intent foodlist = new Intent(RestaurantList.this, Foodlist.class);
foodlist.putExtra("restaurantid", documentSnapshot.getId());
startActivity(foodlist);
}
});
}
}
#Override
protected void onStart() {
super.onStart();
adapter.startListening();
}
#Override
protected void onStop() {
super.onStop();
adapter.stopListening();
}
}

According to your comments, to get all Food documents that exist in all sub-collections according to the menuid property, a Firestore collection group query is needed. This query looks like this:
Query menuIdQuery = db.collectionGroup("Foods").whereEqualTo("menuid", yourMenuId);

You can try with delete the setOnItemClickListener and call intent from cardViewViewHolder.itemView.setOnClickListener
