小编use*_*501的帖子

我正在使用hilt并试图将我的导入SessionManager到我的AuthViewModel班级中。

当查看谷歌关于hilt with ViewModel的文档时，我们可以看到它们能够注入ExampleRepository repository到所述的构造函数中ExampleViewModel

public class ExampleViewModel extends ViewModel {

  private final ExampleRepository repository;
  private final SavedStateHandle savedStateHandle;

  @ViewModelInject
  ExampleViewModel(
      ExampleRepository repository,
      @Assisted SavedStateHandle savedStateHandle)
    {
    this.repository = repository;
    this.savedStateHandle = savedStateHandle;
  }
  ...
}

和

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    exampleViewModel = new ViewModelProvider(this).get(ExampleViewModel.class);
  }

每当我尝试对我的项目执行此操作时，我都会不断收到错误消息。
