无法从GreenRobotEventBus更新回收者视图

Question

[从过去两天开始，我试图设置从Eventbus接收到的回收器视图值，但出现错误，未连接适配器；跳过布局。我已经尝试并测试了互联网上可用的每个代码，例如1. https://github.com/gunhansancar/eventbus-example在适配器中附加数据2. Trying to impact RecyclerView items via EventBus-在适配器类中创建方法，但是什么也没发生

我在事件中得到响应，但无法在回收者视图中使用该响应

代码

  @Subscribe(threadMode = ThreadMode.MAIN)
    fun pickDropChooseEvent (data : PickAddressDone){
        try {
//vehicle list result is a model
            vehicleListResult = data.vehicleListResult

            vehicleAdapter.updateData(vehicleListResult.vehicleCategory!!);
            vehicleAdapter.notifyDataSetChanged();
        }
        catch (exception : Exception )
        {
            Log.d("vehicle info" ,"catch pick drop "+exception.toString())
        }
    }

然后在ViewCreated中我声明了一个方法“ initMembers”来初始化该片段的视图

 private fun initMembers() {
        try{
            vehicleList = ArrayList()
            vehicleList.addAll(vehicleListResponse.vehicleListResult!!.vehicleCategory!!)
            tvDistance.text = vehicleListResult.ride!!.distanceText
            rvVehicleList.setHasFixedSize(true)
            rvVehicleList.layoutManager = LinearLayoutManager(context, LinearLayoutManager.VERTICAL, false)
            rvVehicleList.setAdapter(vehicleAdapter)
           vehicleAdapter = VehicleCategoryAdapter(context!!, vehicleList)


          // i have even tried notify change

        }catch (exception: Exception)
        {
            Log.d("vehicle info", " exception "+exception)
        }

    }

Updat：已解决代码中没有问题，但是问题在Xml ConstraintLayout中。谢谢大家

您应该在onCreateView回调方法中而不在ViewCreated中调用initMembers（）方法>
