DataBinding implementation guide UI on ViewModel Change with LiveData in Android 14
I'm prototyping a solution and I need help solving I'm relatively new to this, so bear with me... Hey everyone, I'm running into an issue that's driving me crazy. I'm working with an scenario where my UI is not updating when the LiveData in my ViewModel changes. I'm using Android 14 and DataBinding in my project, and I've set everything up according to the best practices. However, the UI does not reflect the changes in the LiveData. Here’s a simplified version of my code: In 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: ```kotlin class MyFragment : Fragment() { private lateinit var binding: FragmentMyBinding private lateinit var viewModel: MyViewModel override fun onCreateView( inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle? ): View { binding = DataBindingUtil.inflate(inflater, R.layout.fragment_my, container, false) viewModel = ViewModelProvider(this).get(MyViewModel::class.java) binding.lifecycleOwner = this binding.viewModel = viewModel return binding.root } } ``` In my layout (fragment_my.xml): ```xml <layout xmlns:android="http://schemas.android.com/apk/res/android"> <data> <variable name="viewModel" type="com.example.MyViewModel"/> </data> <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@{viewModel.data}"/> </layout> ``` I've verified that `updateData` is being called properly when I make changes, but the TextView does not update. There are no errors in the logs, and the LiveData observer seems to not be firing as expected. I’ve also checked that the `lifecycleOwner` is set correctly. What could I be missing here? Is there a specific configuration scenario with DataBinding and LiveData in Android 14? How would you solve this? I'm working in a Debian environment. Any advice would be much appreciated. Any help would be greatly appreciated!
