这是我的AllFilesListViewModel课。

class AllFilesListViewModel @ViewModelInject constructor(
    private val pdfItemRepository: PdfItemRepository):ViewModel() {

}

这里是PdfItemRepository课堂。

@Singleton
class PdfItemRepository @Inject constructor(private val pdfItemDao: PdfItemDao){

}

对于pdfItemDao. 我创建了一个名为DatabaseModule. 下面是代码——

@Module
@InstallIn(ApplicationComponent::class)
object DatabaseModule {

    @Provides
    fun provideDatabase(@ApplicationContext context: Context):AppDatabase{
        return AppDatabase.getDataBase(context)
    }

    @Provides
    fun providePdfItemDao(database:AppDatabase):PdfItemDao{
        return database.pdfItemDao()
    }
}

这是AllFilesFragment.kt我使用 viewModel的片段类。

@AndroidEntryPoint
class AllFilesFragment:Fragment(){

    private lateinit var binding:AllFilesFragmentBinding
    private val viewModel by viewModels<AllFilesListViewModel>()


    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? { …

我已正确完成所有操作，但仍然无法在我的项目中使用 Hilt。
