所以，我已经遵循了许多YouTube教程，以正确了解Android中的Retrofit以及如何将响应中的数据传递到我的适配器并显示列表，但现在没有一个对我有效，我不知道为什么。
在我的MainActivity中，我正在调用RetrofitInstance，因此向我的API发起GET请求并从中获取响应。当我调试我的代码并记录响应时，主体是正确可见的，因为它应该是，但是当我试图将该响应以列表的形式传递给适配器时，问题就发生了。
这是两个文件的代码
主活动代码-

class QuizMainActivity : AppCompatActivity() {
    private lateinit var quizCategoryAdapter: QuizCategoryAdapter
    private lateinit var binding: ActivityQuizMainBinding
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityQuizMainBinding.inflate(layoutInflater)
        setContentView(binding.root)
        hideactionbar()
       setupRecyclerView()
        lifecycleScope.launchWhenCreated {
            val response = try{
                RetrofitInstance.api.getQuizCategories()
            }catch (e:IOException){
                Log.d("QuizCatTag", "IOException"+e)
                return@launchWhenCreated
            }catch (e: HttpException){
                Log.d("QuizCatTag", "HTTPException"+e)
                return@launchWhenCreated
            }
            if(response.isSuccessful && response.body()!=null){
                setupRecyclerView()
               quizCategoryAdapter.quizCategoryList = response.body()!!.category_detail //place where I am sending my response list to my adapter. 
                Log.d("quizCategoryList", quizCategoryAdapter.quizCategoryList.toString() )
            }else{
            Log.d("TASG", "Response not successful")
        }
        }
    }
    private fun hideactionbar() {
        supportActionBar?.hide()
    }
    private fun setupRecyclerView() = binding.quizCategoryRv.apply {
       quizCategoryAdapter = QuizCategoryAdapter(this@QuizMainActivity)
        adapter = quizCategoryAdapter
        layoutManager = LinearLayoutManager(this@QuizMainActivity)
    }
}

字符串
适配器代码-（我也在适配器中使用DiffUtils来处理数据的变化）

class QuizCategoryAdapter(
    private val context: Context
) : RecyclerView.Adapter<QuizCategoryAdapter.QuizCategoryHolder>() {
    private val diffCallBack = object: DiffUtil.ItemCallback<CategoryDetail>(){
        override fun areItemsTheSame(oldItem: CategoryDetail, newItem: CategoryDetail): Boolean {
            return oldItem.category_name == newItem.category_name
        }
        override fun areContentsTheSame(oldItem: CategoryDetail, newItem: CategoryDetail): Boolean {
            return oldItem == newItem
        }
    }
    private val differ = AsyncListDiffer(this, diffCallBack)
    var quizCategoryList : List<CategoryDetail>
        get() = differ.currentList
        set(value) {differ.submitList(value)}
  
    val textList  = quizCategoryList.chunked(3)
      
    class QuizCategoryHolder(binding: QuizCategoryItemBinding) : RecyclerView.ViewHolder(binding.root){
   
         val listTextV = listOf(binding.qciTv1, binding.qciTv2, binding.qciTv3)
    }
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): QuizCategoryAdapter.QuizCategoryHolder {
        return QuizCategoryHolder(QuizCategoryItemBinding.inflate(LayoutInflater.from(context), parent,false))
    }
    override fun getItemCount(): Int {
       return textList.size
    }
    override fun onBindViewHolder(holder: QuizCategoryHolder, position: Int) {
     
        for (i in 0 until textList[position].size){
            if(textList[position][i].category_name==""){
                holder.listTextV[i].isVisible = false
            }else{
                holder.listTextV[i].text = textList[position][i].category_name
            }
        }
            holder.itemView.setOnClickListener{
                val intent = Intent(context, QuizQuestionActivity::class.java)
                context.startActivity(intent)
            }
    }
}

我试图通过Retrofit将从API获取的列表显示到RecyclerView适配器中。但不幸的是，当我将列表传递给我的Adapter类时，它仍然显示为null/empty，并且不显示任何内容。
话虽如此，当我试图将列表作为参数传递给class时，它会显示列表。在我看来，我不认为这是正确的方式。
请引导我，让我知道你的想法。实现这一点的最正确的方法是什么？
