Firestore обновляется только при доступе через определенное действие Android. ⇐ JAVA

[Anonymous]

Я работаю над приложением для Android, в котором пользователи могут добавлять и удалять рестораны из избранного с помощью действия RestaurantPage. Когда я получаю доступ к действию RestaurantPage из действия UserFavourites и пытаюсь удалить ресторан из моего избранного, Firestore успешно обновляется, удаляя ресторан из моего избранного в базе данных. Однако когда я захожу в ресторан через действие «Поиск», я не могу удалить его из избранного (Firestore не обновляется при нажатии кнопки «Избранное»). Вот код моей активности RestaurantPage, активности UserFavourites, активности поиска и класса AppManager. Я новичок в разработке Android, поэтому буду очень признателен за любую помощь!
Страница ресторана:


import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.widget.Button;

import java.util.ArrayList;

public class RestaurantPage extends AppCompatActivity {

Button favourited;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
EdgeToEdge.enable(this);
setContentView(R.layout.menu_restaurantpage);
favourited = findViewById(R.id.favouriteButton);

Restaurant currRestaurant = AppManager.getCurrentRestaurant();

ArrayList currFavourites = AppManager.getCurrentUser().getFavourites();
Log.d("CURR USER", AppManager.getCurrentUser().getUsername());

int i = 0;
boolean flag = false;
while (i < currFavourites.size() && !flag){
if (currFavourites.get(i).getName().equals(currRestaurant.getName())){
flag = true;
}
i++;
}

if (flag) {
favourited.setText("Remove from favourites");
}
else {
favourited.setText("Add to favourites");
}

favourited.setOnClickListener((view) -> {
ArrayList currentFavourites = AppManager.getCurrentUser().getFavourites();
int j = 0;
boolean flag2 = false;
while (j < currentFavourites.size() && !flag2) {
if (currentFavourites.get(j).getName().equals(currRestaurant.getName())) {
flag2 = true;
}
j++;
}

if (flag2) {
AppManager.getCurrentUser().removeFavourite(currRestaurant);
favourited.setText("Add to favourites");
}
else {
AppManager.getCurrentUser().addFavourite(currRestaurant);
favourited.setText("Remove from favourites");
}
AppManager.uploadUser(AppManager.getCurrentUser());
});

}

}

Избранное пользователя:


public class UserFavourites extends AppCompatActivity implements AdapterView.OnItemSelectedListener {

private FirebaseAuth authenticate;
private ArrayList userList;

private User currentUser;

private SearchView favouritesBar;

private RecyclerView favouritesRecyclerView;

private SearchAdapter searchAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
EdgeToEdge.enable(this);
setContentView(R.layout.menu_favourites);
authenticate = FirebaseAuth.getInstance();

favouritesRecyclerView = findViewById(R.id.favourites_list);

favouritesRecyclerView.setItemAnimator(new DefaultItemAnimator());
favouritesRecyclerView.addItemDecoration(new DividerItemDecoration(this, LinearLayoutManager.VERTICAL));
currentUser = AppManager.getCurrentUser();
if (currentUser == null){
Log.d( "USER FAIL", "No user found");
startActivity(new Intent(UserFavourites.this, HomeScreen.class));
return;
}
else {
Log.d("USER FOUND", "User found");
}

searchAdapter = new SearchAdapter(currentUser.getFavourites(), UserFavourites.this, new SearchAdapter.ItemClickListener() {
@Override
public void onItemClick(Restaurant restaurant) {
Log.d("NEWPAGE", "User sent to restaurant page for " + restaurant.getName());
AppManager.setCurrentRestaurant(restaurant);
startActivity(new Intent(UserFavourites.this, RestaurantPage.class));
}
});

}

}

Поиск:
public class Search extends AppCompatActivity implements AdapterView.OnItemSelectedListener {

protected ArrayList searchList;

private DrawerLayout nav_layout;

nav_toolbar = findViewById(R.id.nav_toolbar);
nav_view = findViewById(R.id.navigationView);
nav_view.setItemIconTintList(null);

searchRecyclerView = findViewById(R.id.search_list);
searchRecyclerView.setItemAnimator(new DefaultItemAnimator());
searchRecyclerView.addItemDecoration(new DividerItemDecoration(this, LinearLayoutManager.VERTICAL));
searchList = AppManager.getRestaurants();

else {
Log.d("USER FOUND", "User found");

}

searchAdapter = new SearchAdapter(searchList, Search.this, new SearchAdapter.ItemClickListener() {
@Override
public void onItemClick(Restaurant restaurant) {
Log.d("NEWPAGE", "User sent to restaurant page for " + restaurant.getName());
AppManager.setCurrentRestaurant(restaurant);
startActivity(new Intent(Search.this, RestaurantPage.class));

}
});

}
