I am trying to display recyclerview list data using adapter. So far there is no error and I think my code logic is correct, but it didn't show the list when I run the app.

Below is my MainActivity code

```
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    val activityMainBinding = ActivityMainBinding.inflate(layoutInflater)
    setContentView(activityMainBinding.root)
    setSupportActionBar(activityMainBinding.mainToolbar)
    binding = activityMainBinding.contentMain

    val rv = binding.recyclerView
    val clickListener = { view: View, bandName:String ->
        //Deal with click feature later, show the list first
    }
    adapter = RVAdapter(clickListener)
    rv.adapter = adapter
    rv.layoutManager = LinearLayoutManager(this)
    adapter.submitlist(bandResources.values.toMutableList())

```

Below is my RVAdapter code

```
class RVAdapter(private val clickListener: (view:View, bandName: String)->Unit)
    : ListAdapter<BandInfo,RVAdapter.ViewHolder>(Diff())
{    
    inner class ViewHolder(val bandRowBinding : BandRowBinding)
        : RecyclerView.ViewHolder(bandRowBinding.root) {
        init {
            bandRowBinding.root.setOnClickListener{
                //Deal with click feature later, show the list first
            }
        }
    }    
    private var bands = mutableListOf<BandInfo>()   
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
        val bandRowBinding = BandRowBinding.inflate(LayoutInflater.from(parent.context),
            parent, false)
        return ViewHolder(bandRowBinding)
    }    
    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        val binding = holder.bandRowBinding
        bands[position].let{
            binding.bandTitle.text = it.name
            binding.bandCreated.text = it.time
        }
    }    
    fun submitlist(items: MutableList<BandInfo>){
        bands = items
    }

```

Where did I go wrong?
