Android Studio calculate total price

I wanna ask how can I sum all patty price and display in the total ? The total is in activity_main.xml layout while all the product price is in view_product.xml .
Screenshot of app
As you can see the grey color text is per patty price , and the right side black text is price after multiply the quantity of patty. I want all the black text to sum up and show at below total.

In view_product.xml you are only displaying the price, but that's not where the actual data is located so your question shouldn't be that the prices are in view_product.xml and you want to show in activity_main.xml, but your question should be -
Where is the data located
How to make the necessary calculations
Where to show it. .
Your data regarding the prices are in products object. So, in order to calculate the total you just need to add one more method which calculates the total
private double calculateTotal(ProductDataSet productDataSet) {
double totalPrice = 0.0;
for(int i=0; i<productDataSet.size(); i++) {
totalPrice += productDataSet.get(i).getPrice();
}
return totalPrice;
}
The result of this you can store in a new value or show directly in the textView itself.
((TextView)findViewById(R.id.finalTotalPrice)).setText(calculateTotal(products).toString());
This you can call anywhere after createInitialProductList(). I hope this helps and makes it clear for you.

Firestore data can't display on RecyclerView

The app quit when I change the line I am facing a problem when I try to develop an Android App that display the data from Firestore.
.
Can I know why it is not displaying the data on my RecyclerView and EventPage? I have rechecked everything, but I still can't find out why data doesn't show on EventPage.
EventPage.java

private static final String TAG = "DashboardFragment";

adapter = new FirestoreRecyclerAdapter<EventModel, EventViewHolder>(options) {
#Override

holder.textViewEDate.setText(model.getEDate());
holder.textViewEVenue.setText(model.getEVenue());
holder.textViewEDesc.setText(model.getEDesc());
}
#NonNull
#Override
public EventViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
//Changes on XML file. Try it.

make Sure your model class String variables are equal to your firestore data feild because it is very important to retrieve data from firestore
private String eventName;
private String eventDate;
private String eventVenue;
private String eventDescription;
//Constructor
public EventModel(){}
public EventModel(String eventName, String eventDate, String eventVenue, String eventDescription){
this.eventName = eventName;
this.eventDate = eventDate;
this.eventVenue = eventVenue;
this.eventDescription = eventDescription;
}
public String geteventName() {
return eventName;
}
public void seteventName(String eventName) {
this.eventName = eventName;
}
public String geteventDate() {
return eventDate;
}
public void seteventDate(String eventDate) {
this.eventDate = eventDate;
}
public String geteventVenue() {
return eventVenue;
}
public void seteventVenue(String eventVenue) {
this.eventVenue = eventVenue;
}
public String geteventDescription() {
return eventDescription;
}
public void seteventDescription(String eventDescription) {
this.eventDescription = eventDescription;
}

This looks wrong:
Query query = db.collection("event").orderBy("ASC").limit(10);
You are telling Firestore to sort by a field called ASC, which doesn't exist in your screenshot, so no documents are returned.
You probably want to sort on the ascending date, which you can do with:
Query query = db.collection("event").orderBy("eventDate", Direction.ASCENDING).limit(10);
Note that while the above will fix the problem of the documents not showing, they will still show up in the wrong order. This is because your eventDate field is not useful for sorting dates.
Strings in Firestore are sorted lexicographically, and in that order, "12/7/2021" becomes before "13/6/2021".
If you want to fix this problem, you can either store the dates as Firestore's built-in Timestamp type, or use a string format that allows sorting, like "2021-07-12" (which is *after* "2021-07-13"`.

Data binding user model and login

I am trying to incorporate a user model into my application while using data binding. And I am trying to get the user to sign up using firebase authentication email and password. But when my sign up button is clicked nothing happens.
I have a way for my login activity working using my own custom observable string class but I am just trying out a different method for this.
my user model:
public class User extends BaseObservable {
private String email;
private String password;
private String confPassword;
private String username;
#Bindable
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
notifyPropertyChanged(BR.email);
}
#Bindable
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
notifyPropertyChanged(BR.password);
}
#Bindable
public String getConfPassword() {
return confPassword;
}
public void setConfPassword(String confPassword) {
this.confPassword = confPassword;
notifyPropertyChanged(BR.confPassword);
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
signUpViewModel:
public class SignUpViewModel extends ViewModel {
public void firebaseSignUp(String email, String password, String confPassword){
if (!TextUtils.isEmpty(email) && !TextUtils.isEmpty(password) && !TextUtils.isEmpty(confPassword)) {
if (android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches()) {
if (password.length() > 6) {
if (password.equals(confPassword)) {
FirebaseAuth.getInstance().createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {

well found the answer, I was just missing a line of code:
signUpBinding.setUser(user);
works after I added this in.

CardView not displaying content due any errors

I created a Recyclerview in my main_activity and I wanted to use this cardview in a partial activity... I put extras variables and data to the new activity but any thing not showing in new activity...
this is my partial xml code (hotel_page.xml) :

This is My HotelPageList.java :

public class HotelPageAdapter extends RecyclerView.Adapter<HotelPageAdapter.MyViewHolder> {
private Context mContext;
private List<HotelPageList> hotelPage;
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title1, count1;
public ImageView thumbnail1, overflow1;
public MyViewHolder(View view) {
super(view);

}

this.hotelPage = hotelPage;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.hotel_page, parent, false);
return new MyViewHolder(itemView);
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
final HotelPageList hotel = hotelPage.get(position);
holder.title1.setText(hotel.getName());
holder.count1.setText(hotel.getNumOfRooms() + " اتاق");
// loading hotel cover using Glide library
Glide.with(mContext).load(hotel.getThumbnail()).into(holder.thumbnail1);
}
#Override
public int getItemCount() {return hotelPage.size();}
}
and this is result:
