Hello, how I can transfer the realization of interface class into hilt in my ViewModel. I can't use @Binds, because after creating ViewModel I should fulfil some method to calculate the required realization of this interface.

Nice one. Can we use constructor injection to inject viewmodel in the same fragment?

@abhisheksaxena518 4 жыл бұрын

After going through some stackoverflow answers and issue trackers, if you have to setup actionbar with navcontroller then FragmentContainerView will not be able to find the associated NavController. In order to resolve this issue, simply replace it with and find the controller traditionally like navController = findNavController(R.id.default_navHost_fragment) Bug Report: issuetracker.google.com/issues/142847973

What if we inject the factory into a method then set the fragment factory inside it? @Inject fun setFactory(factory: CustomFactory) { supportFragmentManager.fragmentFactory = factory } Since the injection is done before the call to super.onCreate() Please correct me if I’m wrong

@JohnDoe-wx3zm 2 жыл бұрын

Mitch, is constructor injection that big of a deal? The whole FragmentFactory thing seems like a lot of boilerplate, especially when you can just field inject (I know filed injection is supposed to be bad, but does the FragmentFactory have any tangible upsides?)

How to use viewBinding with such a fragment? Since it directly takes in the layout

@devanshu_on_youtube 4 жыл бұрын

I suggest creating an abstract base class for a view-binding fragment that uses the usual Fragment() empty constructor and inflate the view using DataBindingUtil in the onCreateView method. You can still provide the layout as a dependency in the constructor of this base class, and have full control over whether you choose to use the helpful Fragment constructor with the layooutId or use DataBindingUtil instead. Hope that helps :)

How is the injection working in your NavHostFragment if you're using the value in onAttach? onAttach comes before onCreate in the lifecycle of the Fragment. When does Hilt do injection in the Fragment lifecycle?

@codingwithmitch 3 жыл бұрын

In on attach for fragments. Same as with dagger.

Having Fragment with non default constructor that contains parameters is totally wrong. Because when the Activity killed by system and after coming back to the app, system can't recreate the fragment

@vasiliychernov2123 Жыл бұрын

That's the reason they introduced FragmentFactory, you provide your own factory which knows how to create your Fragment with non-default constructor.
