RecyclerView with DiffUtil implementation guide correctly when using LiveData in Android 14
I tried several approaches but none seem to work. I've been working on this all day and I'm working with a `RecyclerView` that uses `DiffUtil` to update its items when I receive new data through a `LiveData` object... However, I’m working with an scenario where the changes are not reflected in the UI even after the data source is updated. The `DiffUtil` is configured correctly, but it seems that the `RecyclerView` adapter is not being notified of the changes. In my implementation, I have a `ViewModel` with a `LiveData<List<Item>>`. When the `items` list is updated, I call `adapter.submitList(newList)` to update the UI. Here’s a snippet of how I'm observing the data: ```kotlin viewModel.items.observe(viewLifecycleOwner) { newList -> adapter.submitList(newList) } ``` I ensured that the `DiffUtil.ItemCallback<Item>` is overridden properly: ```kotlin class ItemDiffCallback : DiffUtil.ItemCallback<Item>() { override fun areItemsTheSame(oldItem: Item, newItem: Item): Boolean { return oldItem.id == newItem.id } override fun areContentsTheSame(oldItem: Item, newItem: Item): Boolean { return oldItem == newItem } } ``` However, when the list is updated, I still see the old data in the `RecyclerView`. I've tried adding logs to check if the `observe` function is triggered and if `submitList` is being called with the correct data. The logs show that the new data is indeed different from the old data, so `DiffUtil` should recognize that there are changes. I suspect there might be something related to the lifecycle of the `LiveData` or the way I'm using `submitList`. I’m using Android 14 and the latest version of the `RecyclerView` library. Can anyone guide to troubleshoot why my `RecyclerView` isn't updating as expected? I'm open to any suggestions. I'm working in a Ubuntu 22.04 environment. Is this even possible?
