Data Binding implementation guide UI After LiveData Change in Fragment with ViewModel
I can't seem to get I've encountered a strange issue with I just started working with I'm working on a personal project and I'm working with an scenario where my UI is not updating when the LiveData in my ViewModel changes... I'm using Android Studio Bumblebee (2021.1.1) and `androidx.lifecycle:viewmodel-ktx:2.4.1`. My setup involves Data Binding in a Fragment, and I have a LiveData object that should trigger updates to the UI, but it doesn't seem to work. Here’s a snippet of my ViewModel: ```kotlin class MyViewModel : ViewModel() { private val _data = MutableLiveData<String>() val data: LiveData<String> get() = _data fun updateData(newData: String) { _data.value = newData } } ``` In my Fragment, I’ve set up data binding like this: ```kotlin class MyFragment : Fragment() { private lateinit var binding: FragmentMyBinding private val viewModel: MyViewModel by viewModels() override fun onCreateView( inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle? ): View? { binding = DataBindingUtil.inflate(inflater, R.layout.fragment_my, container, false) binding.lifecycleOwner = this binding.viewModel = viewModel return binding.root } } ``` In my layout XML, I have the following to bind the LiveData: ```xml <TextView android:id="@+id/myTextView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@{viewModel.data}" /> ``` When I call `viewModel.updateData("New Value")`, I can see in the logs that the LiveData is updated, but the TextView doesn't reflect this change. I’ve double-checked that the `lifecycleOwner` is set correctly, and I can confirm that the TextView is properly linked to the LiveData in the layout. I also tried using `notifyPropertyChanged` with a custom binding adapter, but it didn’t help either. I suspect there might be some scenario with the lifecycle or how Data Binding is set up, but I need to figure out what I might be missing. Any ideas on why the UI isn’t updating as expected? I'm working on a web app that needs to handle this. I'm coming from a different tech stack and learning Kotlin. Is this even possible? Thanks for any help you can provide!
