This article explains how to use ViewModels in custom views :
class SummaryView(context: Context, attrs: AttributeSet?) : ConstraintLayout(context, attrs) {
private val viewModel by lazy {
ViewModelProvider(findViewTreeViewModelStoreOwner()!!).get<SummaryViewModel>()
}
override fun onAttachedToWindow() {
super.onAttachedToWindow()
viewModel.summaryModel.observe(findViewTreeLifecycleOwner()!!, ::populateSummaryView)
}
}
It works well, but how can I use this technique using StateFlow instead of LiveData? How can I do this without having a reference to the fragment?
class SummaryView(context: Context, attrs: AttributeSet?) : ConstraintLayout(context, attrs) {
private val viewModel by lazy {
ViewModelProvider(findViewTreeViewModelStoreOwner()!!).get<SummaryViewModel>()
}
override fun onAttachedToWindow() {
super.onAttachedToWindow()
lifecycleScope.launch {
viewLifecycleOwner.repeatOnLifecycle(Lifecycle.State.STARTED) {
viewModel.summaryModel.collect {
}
}
}
}
}
