MVVM architecture component - how to inject the viewmodel in fragment?












0















I have the following code:



public class ProjectFragment extends LifecycleFragment implements Injectable {

@Inject
ViewModelProvider.Factory viewModelFactory;
private ProjectViewModel viewModel


@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);

viewModel = ViewModelProviders.of(this, viewModelFactory)
.get(ProjectViewModel.class);

// …
}


Source code from :https://proandroiddev.com/mvvm-architecture-viewmodel-and-livedata-part-2-di-1a6b1f96d84b



I would like to use directly the @Inject ProjectViewModel. How can I do that?
I didn't find any example.

  • Inject ViewModel directly impossible. You can do it only with factory. You can check this answer stackoverflow.com/a/44506312/9060113 and Google sample repository github.com/googlesamples/android-architecture-components/blob/…

  • Thx @p.alexey. But why is impossible? Because there's no way to actually pass in a module provider the activity/ fragment context, right?

  • Because, for correct work you can't create ViewModel directly, only through the ViewModelProviders ViewModelProviders.of(this).get(MyViewModel.class). And inject property through factory is a good approach.
