In order to call a method in a custom view from a ViewModel, you need to follow the below steps:
Define a custom interface for the view in the ViewModel, with a method that you want to call from the ViewModel.
Implement this interface in your custom view.
In the ViewModel, create an instance of the custom view by passing the reference of the interface implementation to the constructor of the custom view.
Now you can call the defined method in the interface from the ViewModel instance.
Example:
interface MyCustomViewInterface {
fun doSomething()
}
class MyCustomView(context: Context, attrs: AttributeSet?) :
View(context, attrs), MyCustomViewInterface {
override fun doSomething() {
// Implementation of the method
}
}
class MyViewModel(private val customViewInterface: MyCustomViewInterface){
fun callMyViewMethod() {
customViewInterface.doSomething()
}
}
callMyViewMethod()
method in the ViewModel, which in turn calls the doSomething()
method in the custom view.Please start posting anonymously - your entry will be published after you log in or create a new account. This space is reserved only for answers.
