MVVMwithRetrofit-如何处理Repository中的大量LiveData？

我正在关注这个关于使用 MVVM 和 Retrofit 的教程

用户将 MutableLiveData 放置在 Repository 类中的位置：

public class MovieRepository {
    private static final ApiInterface myInterface;
    private final MutableLiveData<EntityMovieOutputs> listOfMovies = new MutableLiveData<>();

private static MovieRepository newsRepository;

    public static MovieRepository getInstance(){
        if (newsRepository == null){
            newsRepository = new NewsRepository();
        }
        return movieRepository;
    }

    public MovieRepository(){
        myInterface = RetrofitService.getInterface();
    }

I'm building a simple app and what I noticed is my repository class is quickly being filled with a lot of MutableLiveData objects. Is this actually the correct way to implement MVVM, LiveData, and the Repository pattern?

Edit1:________________________________________________

I've created an AdminLiveData object that just holds the LiveData and has getters.

But how would I get reference to the ViewModel inside my AdminRepo class so I can notify the LiveData inside the ViewModel when the Retrofit Network call is complete?

private AdminService  adminService;
    
public AdminRepo(Application application) {
        BaseApplication baseApplication = (BaseApplication) application;
        RetrofitClient client = baseApplication.getRetrofitClient();
        adminService = client.getRetrofit().create(AdminService.class);  

        //AdminViewModel viewModel = (AdminViewModel) .... 
        // Not sure how to get reference to the viewmodel here so I can get the 
        // LiveData object and call postValue after the retrofit calls
}

    public void getFirstPageMembers(int offset, int limit) {
        adminService.getUsersPaginitation(offset, limit).enqueue(new Callback<List<UserInfo>>() {
            @Override
            public void onResponse(@NonNull Call<List<UserInfo>> call, @NonNull Response<List<UserInfo>> response) {
                if (response.body() != null) {
                    //firstPageLiveData.postValue(response.body());
                    //Since I create the LiveData inside the ViewModel class 
                   //instead, how do I get reference to the ViewModel's LiveData?
                }
            }

            @Override
            public void onFailure(@NonNull Call<List<UserInfo>> call, @NonNull Throwable t) {
                //firstPageLiveData.postValue(null);
            }
        });
    }

The AdminViewModel:

public class AdminActivityViewModel extends AndroidViewModel {

    private AdminRepo repo;

    private AdminLiveData adminLiveData = new AdminLiveData();
    
    public AdminActivityViewModel(@NonNull Application application) {
        super(application);

        repo = new AdminRepo(application);
    }

How do I get reference to the AdminViewModel from inside my AdminRepo class?
