Updating Data Causes Recycler View (List Adapter) To Move The Data To The End

Question

I am using List Adapter to display a list of strings.

Whenever I update data on the recycler view it scrolls the data to the end of the list

Any idea what is causing this?

for reference below is the code for the adapter

class TestAdapter(private val taskListener: DetailTaskAdapterListener) : ListAdapter<Task, TestAdapter.TestViewHolder>(DiffUtilCallback) {

    inner class TestViewHolder(private val binding: DetailSubTaskItemBinding) :
        RecyclerView.ViewHolder(binding.root) {
        fun bind(task: Task) {
            binding.checkbox.isChecked = task.isComplete
            binding.task.setText(task.task.trim())
        }

        fun setupListener() {
            binding.checkbox.setOnCheckedChangeListener { _, isChecked ->
                if (isChecked) {
                    binding.task.paintFlags = Paint.STRIKE_THRU_TEXT_FLAG
                } else {
                    binding.task.paintFlags = 0
                }
                getItem(absoluteAdapterPosition).copy(isComplete = isChecked)
            }

            binding.task.setOnFocusChangeListener { view, hasFocus ->
                if(!hasFocus){
                    if(binding.task.text.toString().trim().isEmpty()){
                        taskListener.deleteTask(getItem(absoluteAdapterPosition).taskId)
                    }else{
                        taskListener.updateTask(getItem(absoluteAdapterPosition).taskId, binding.task.text.toString().trim())
                    }
                }
            }
        }
    }

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): TestViewHolder {
        val layoutInflater = LayoutInflater.from(parent.context)
        return TestViewHolder(
            DetailSubTaskItemBinding.inflate(
                layoutInflater, parent, false
            )
        )
    }

    override fun onBindViewHolder(holder: TestViewHolder, position: Int) {
        val task = getItem(position)
        holder.setupListener()
        holder.bind(task)
    }

    companion object DiffUtilCallback : DiffUtil.ItemCallback<Task>() {
        override fun areItemsTheSame(oldItem: Task, newItem: Task): Boolean {
            return oldItem.task == newItem.task
        }

        override fun areContentsTheSame(oldItem: Task, newItem: Task): Boolean {
            return oldItem == newItem
        }
    }
}

code below is the DAO, (note: both insert and update function causes recyclerview to push updated data to the last row)

@Transaction
@Query("SELECT * FROM todo WHERE todoId = :todoId")
fun getTodoDetails(todoId: String): Flow<TodoDetailsEntity>

@Insert(onConflict = OnConflictStrategy.REPLACE)
suspend fun insertTask(task: TaskEntity): Long

@Query("UPDATE task SET task = :title WHERE taskId = :taskId")
suspend fun updateTaskTitle(taskId: String, title: String): Int

Below is the entity model

data class TodoDetailsEntity(
    @Embedded val todo: TodoEntity,
    @Relation(
        parentColumn = "todoId",
        entityColumn = "todoRefId"
    )
    val tasks: List<TaskEntity>,
    @Relation(
        parentColumn = "todoId",
        entityColumn = "noteId"
    )
    val note: NoteEntity?,
    @Relation(
        parentColumn = "todoId",
        entityColumn = "todoRefId"
    )
    val attachments: List<AttachmentEntity>
)

submitList is called in Activity onCreate

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        viewModel.saveTodoId(intent.extras?.getString("todoId")!!)
        todoId = intent.extras?.getString("todoId")
        binding = ActivityDetailsBinding.inflate(layoutInflater)
        setContentView(binding.root)
        setupToolbar()
        setupTestAdapter()
        collectLatestLifecycleFlow(viewModel.uiState) { uiState ->

            testAdapter.submitList(uiState.todoDetails?.tasks)
        }
    }

For reference, whenever I update the data to database, ROOM will automatically move the data to the last index

Before updating

After update
