android - 切换到夜间模式时我的应用程序崩溃

问题描述

<style name="Theme.Foodly" parent="Theme.AppCompat.DayNight.NoActionBar">

    lateinit var recl_view:RecyclerView
    recl_view = view.findViewById(R.id.frg_main_rec_view)
    recl_view.layoutManager = LinearLayoutManager(activity)
    recl_view.adapter = MainAdapter(activity as Context,list)

错误显示在这里

 Process: com.example.foodly, PID: 9860
     kotlin.UninitializedPropertyAccessException: lateinit property recl_view has not been initialized

仅当我们从暗模式切换到亮模式时才会显示此错误，反之亦然。
