无法使用 viewpager 和 tablayout 创建类 viewmodel 的实例

如何解决无法使用 viewpager 和 tablayout 创建类 viewmodel 的实例

我正在实现 MVVM 并使用 viewpager2，并在片段上附加了 tablayout
我为 tablayout 的每个片段都有一个 viewmodel 类，我收到了这个运行时错误
"无法使用viewpager创建类viewmodel的实例

这是我的视图模型类：

public class Cranesviewmodel extends Androidviewmodel {
    private IndustrialCranesRepository repository;
    private LiveData<List<TrackingModel>> allIndustrialTrackingItems;


    public Cranesviewmodel(@NonNull Application application) {
        super(application);
        repository = new IndustrialCranesRepository(application);
        allIndustrialTrackingItems = repository.getAllIndustrialData();

    }

    public LiveData<List<TrackingModel>> getAllIndustrialTrackingItems() {
        return allIndustrialTrackingItems;
    }

public class Constructionviewmodel extends Androidviewmodel {

    private ConstructionPortMaritimeRepository repository;
    private LiveData<List<ConstructionModel>> allConstructionTrackingItems;


    public Constructionviewmodel(@NonNull Application application) {
        super(application);
        repository = new ConstructionPortMaritimeRepository(application);

        allConstructionTrackingItems = repository.getAllConstructionData();
    }

    public LiveData<List<ConstructionModel>> getAllConstructionTrackingItems()
    {
        return allConstructionTrackingItems;
    }

}

片段代码：

  @Override
    public void onViewCreated(@NonNull View view,@Nullable Bundle savedInstanceState) {
        super.onViewCreated(view,savedInstanceState);
        viewmodel = new viewmodelProvider(requireActivity()).get(Constructionviewmodel.class);

        viewmodel.getAllConstructionTrackingItems().observe(requireActivity(),new Observer<List<ConstructionModel>>() {
            @Override
            public void onChanged(List<ConstructionModel> constructionModels) {
                ConstructionAdapter adapter = new ConstructionAdapter(constructionModels,ConstructionFragment.this);
                constructionRecyclerView.setAdapter(adapter);
                adapter.notifyDataSetChanged();
            }
        });

为什么我会收到此错误？
