下面是我的Fragment1.kt整体代码

class Fragment1 : Fragment() {
    private lateinit var binding: Fragment1Binding
    private lateinit var list : ArrayList<TasksItem>
    private lateinit var recyclerView: RecyclerView
    private lateinit var manager: RecyclerView.LayoutManager
    private lateinit var myAdapter: RecyclerView.Adapter<*>
    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_1, container, false)
    }
    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        recyclerView = view.findViewById(R.id.app_list)
        recyclerView.setHasFixedSize(true)
        list = arrayListOf()
        manager = LinearLayoutManager(this.requireContext())
        GroomedKidzApi.retrofitService.getTasksProgress().enqueue(object :
            Callback<List<TasksItem>?> {
            override fun onResponse(
                call: Call<List<TasksItem>?>,
                response: Response<List<TasksItem>?>
            ) {
                val responseBody = response.body()
                if (responseBody != null) {
                    recyclerView = view.findViewById<RecyclerView>(R.id.app_list).apply {
                        myAdapter = TaskAdapter(response.body()!!)
                        layoutManager = manager
                        adapter = myAdapter
                        Log.e("TAG", "response 33: "+ (response.body()) )
                    }
                }
            }
            override fun onFailure(call: Call<List<TasksItem>?>, t: Throwable) {
            }
        })
        var adapter = TaskAdapter(list)
        recyclerView.adapter = adapter
        adapter.setOnItemClickListener(object : TaskAdapter.OnItemClickListener {
            override fun onItemClick(position: Int) {
                    val intent = Intent(activity,ViewTaskActivity::class.java).apply{
                        putExtra("taskname", list[position].taskName)
                        putExtra("desc", list[position].taskDesc)
                        putExtra("category", list[position].category)
                        putExtra("duedate", list[position].dueDate)
                        putExtra("assignee", list[position].assignee)
                        putExtra("point", list[position].pointEarned)
                        Log.d("Fragment1", "onViewCreated executed")
                }
                startActivity(intent)
            }
        })
    }
}

字符串
下面是TaskAdapter的整体代码

class TaskAdapter(val list: List<TasksItem> ) : RecyclerView.Adapter<TaskAdapter.MyViewHolder>() {
    private var listener2: OnItemClickListener? = null
    interface OnItemClickListener {
        fun onItemClick(position: Int)
    }
    fun setOnItemClickListener(listener: OnItemClickListener){
        listener2 = listener
    }
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
        val itemView = LayoutInflater.from(parent.context).inflate(R.layout.item,
            parent,false)
        return MyViewHolder(itemView,listener2)
    }
    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        val currentitem = list[position]
        holder.TaskName.text = currentitem.taskName
        holder.Date.text = currentitem.dueDate
        holder.Assignee.text = currentitem.assignee
        holder.Status.text = currentitem.taskStatus
    }
    override fun getItemCount(): Int {
        return list.size
    }
    class MyViewHolder(itemView : View, listener: OnItemClickListener?) : RecyclerView.ViewHolder(itemView){
        val TaskName : TextView = itemView.findViewById(R.id.tvTaskname)
        val Assignee : TextView = itemView.findViewById(R.id.tvAssignee)
        val Date : TextView = itemView.findViewById(R.id.tvDate)
        val Status : TextView = itemView.findViewById(R.id.tvStatus)
        init {
            itemView.setOnClickListener{
                listener?.onItemClick(adapterPosition)
            }
        }
    }
}

onItemClick内部的Log.d("Fragment1", "onViewCreated executed")的logcat没有被调用。但是，可以成功调用其他函数。
为什么onItemClick没有被调用？所有函数都工作正常，即使是API。
注：适配器很好，setOnClickListener也能得到位置
