将数据从 BroadcastReceiver 传递到 ViewModel 或 Repository

Question

我正在尝试发送我在视图模型或存储库中的广播（在清单中注册）中收到的数据并不是特别重要，我尝试通过实时日期和 RxJava2 来完成，但是广播中有数据 class 我可以看到，但它不会进入视图模型或存储库，谢谢。

class MyBroadcastReceiver  : BroadcastReceiver() {

private val dataList = MutableLiveData<ArrayList<Words>>()
private var observer: Observable<ArrayList<Words>> = Observable.just(arrayListOf())

@SuppressLint("CheckResult")
override fun onReceive(context: Context?, intent: Intent?) {



    val arrayObject =
        intent?.extras?.getParcelableArrayList<Words>("KEY") as ArrayList<Words>?
   
    dataList.postValue(arrayObject)

    arrayObject.let { dataList.postValue(it) }

    arrayObject.let { observer = Observable.just(it) }

    observer = Observable.create { emitter: ObservableEmitter<ArrayList<Words>> ->
            emitter.onNext(arrayObject!!)
            emitter.onComplete()
        }
}

fun getDataList() : LiveData<ArrayList<Words>> = dataList

fun getDataListRx() : Observable<ArrayList<Words>> = observer
    .subscribeOn(Schedulers.io())
    .observeOn(AndroidSchedulers.mainThread())
}

ViewModel class:

class MyViewModel(
private val broadcastReceiver: MyBroadcastReceiver,
private val activity: DaggerActivity) : ViewModel() {

init {
    test()
}

@SuppressLint("CheckResult")
private fun test() {
    broadcastReceiver.getDataListRx()?.subscribe({
        Log.d("WAS_INTENT", "DateRepSuccess")

    },{
        Log.d("WAS_INTENT", "DateRepError")

    })

    broadcastReceiver.getDataList().observe(activity, Observer {
        Log.d("WAS_INTENT", "DateRepSuccessLiveData")

    })
}}

经过多次尝试，我发现 liveData 有效，所以也许有人会需要它。 RxJava 仍然没有，我还不知道为什么。
