如何修复android中RxBus中的调用复制方法

为什么不帮助我呢？

在我的应用程序中，我希望使用

RxBus

处理事件，使用MVP设计模式！我想在单击一个

recyclerview

项目时，调用

fragment

中的一个方法
为此，我使用了RxBus
我写了下面的代码，但当点击物品时调用2次方法

RxBus代码：

object RxBus {

    private val publisher = PublishSubject.create<Any>()

    fun publish(event: Any) {
        publisher.onNext(event)
    }

    fun <T> listen(eventType: Class<T>): Observable<T> = publisher.ofType(eventType)
}

class DashboardAvatarsFragment : RoundedBottomSheetDialogFragment(), DashboardAvatarsContracts.View {

    @NonNull
    private lateinit var presenter: DashboardAvatarsPresenterImpl
    private lateinit var token: String
    private lateinit var layoutManager: GridLayoutManager
    private lateinit var adapter: DashboardAvatarsAdapter
    @NonNull
    private var disposable: Disposable? = null

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_dashboard_avatars, container, false)
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        //Initialize
        presenter = DashboardAvatarsPresenterImpl(requireContext(), this)
        layoutManager = GridLayoutManager(requireContext(), 5)
        //Get token
        token = GoodPrefs.getInstance().getString(PrefsKey.USER_JWT_TOKEN.name, "")
        //Send avatar
        disposable = RxBus.listen(EventUpdateAvatar.UpdateAvatar::class.java).subscribe {
            if (it.updateType == EVENTS_UPDATE_SEND_AVATAR) {
                Log.e("uploadAvatarLog", "Event")
                presenter.sendAvatarId(token, it.avatarId)
            }
        }

        //Get avatars list
        presenter.loadData(token)
    }

    override fun showAvatars(res: DashboardAvatarsResponse.Res) {
        adapter = DashboardAvatarsAdapter(requireContext(), res.avatars, res.baseUrl)
        dashboardAvatars_recyclerView.initRecyclerView(layoutManager, adapter)
    }

    override fun updateAvatar() {
        RxBus.publish(EventUpdateAvatar.UpdateAvatar(EVENTS_UPDATE_AVATAR, ""))
        Log.e("uploadAvatarLog", "Receive")
    }
}

我使用了

Log.e
