我有一个RecyclerView列表，在其中显示来自Firestore的所有文档（每个文档都有自己的带有数据的集合），问题是当单击列表项时，如何在新片段中显示来自Firestore的其相应数据
My Firestore collection

在Recycler视图中，我只显示每个项目的名称和图像，但在单击项目后，我想打开一个新片段，其中包含集合中的所有字段
视图模型

class MainViewModel: ViewModel() {
    private val db = FirebaseFirestore.getInstance()
    private val auth = FirebaseAuth.getInstance()
    private val documentsLiveData = MutableLiveData<List<Card>>()

    fun getDocuments() {
        if (auth.currentUser != null){
            db.collection("cards")
                .get()
                .addOnSuccessListener { documents ->
                    val cardList = mutableListOf<Card>()
                    for (document in documents) {
                        val card = document.toObject(Card::class.java)
                        cardList.add(card)
                    }
                    documentsLiveData.value = cardList
                }
                .addOnFailureListener { exception ->
                    Log.e("Document error", exception.message.toString())
                }
        }
        else{
            Log.e("Document error", "Toast error")
        }

    }

    fun getDocumentsLiveData(): LiveData<List<Card>> {
        return documentsLiveData
    }
    

}

适配器

class CardAdapter(private val context: Context,
                  private val list: List<Card>) : RecyclerView.Adapter<CardAdapter.MyViewHolder>() {

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
        val view = LayoutInflater.from(parent.context).inflate(R.layout.item_layout, parent, false)
        return MyViewHolder(view)
    }

    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        val item = list[position]
        holder.itemView.card_name.text = item.name
        holder.itemView.card_description.text = item.description
        Glide.with(context)
            .load(item.img)
            .into(holder.itemView.card_img)
    }

    override fun getItemCount(): Int {
        return list.size

    }

    class MyViewHolder(view: View) : RecyclerView.ViewHolder(view){

    }
}

主片段

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        viewModel = ViewModelProvider(this)[MainViewModel::class.java]

        viewModel.getDocumentsLiveData().observe(viewLifecycleOwner) { cardList ->
            binding.progBar.visibility = View.GONE
            val adapter = CardAdapter(requireContext(), cardList)
            binding.mainRecycler.adapter = adapter
        }
        viewModel.getDocuments()
    }

我试着按元素id搜索，但没有成功
