Я создал приложение для супружеских отношений, в котором все данные аутентифицированных пользователей в базе данных firebase извлекаются в карточку программы восстановления, но изображения с ним не извлекаются, изображение последнего аутентифицированного пользователя в базе данных применяется ко всем пользователям в recyclerview.
Изображение аутентифицированного пользователя в базе данных
Снимок mainImage (URL-адреса изображения), хранящийся в базе данных Firebase
Изображение хранится в подузле, потому что всякий раз, когда я обновляю изображение в это время, все данные в аутентифицированном узле удаляются, а узел mainImage обновляется.
Это код профиля поиска:
public class Search_Profile extends AppCompatActivity {
private SwipeRefreshLayout mSwipeRefreshLayout;
DatabaseReference databaseReference;
Firebase firebase;
List<User> list = new ArrayList<User>();
RecyclerView recyclerView;
Boolean isScrolling = false;
Context context;
public Search_Profile() {
}
FirebaseRecyclerPagingAdapter<User, UserViewHolder> adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search__profile);
mSwipeRefreshLayout = findViewById(R.id.swipe_refresh_layout);
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(Search_Profile.this));
databaseReference = FirebaseDatabase.getInstance().getReference().child(Dashboard.Database_Path);
