viewmodelproviders deprecated
The ViewModelProviders
class in Kotlin has been deprecated in recent versions of Android. This class was previously used to obtain instances of ViewModel
in an activity or fragment.
To address this deprecation, we can use the ViewModelProvider
class instead. Here are the steps to migrate from ViewModelProviders
to ViewModelProvider
:
Import the
ViewModelProvider
class:kotlin import androidx.lifecycle.ViewModelProvider
Create an instance of
ViewModelProvider
using theViewModelProvider
constructor, passing in theViewModelStoreOwner
(such as the activity or fragment) and an optionalViewModelProvider.Factory
:kotlin val viewModelProvider = ViewModelProvider(this)
Use the
get()
method of theViewModelProvider
instance to obtain an instance of the desiredViewModel
class. Pass in the class name of theViewModel
as the parameter:kotlin val viewModel = viewModelProvider.get(YourViewModel::class.java)
You can now use the
viewModel
instance to interact with your ViewModel as usual.
That's it! By following these steps, you can migrate from using ViewModelProviders
to using ViewModelProvider
in Kotlin.
