Why are you not create the lib for retranslate from RxJO->LD?
Hi,我看你的写法转换后还需要手动Dispose?
`private class LiveDataObservable(
private val liveData: LiveData,
private val valueIfNull: T? = null
) : Observable() {
override fun subscribeActual(observer: io.reactivex.Observer<in T>) {
if (!checkMainThread(observer)) {
return
}
val relay = RemoveObserverInMainThread(observer)
observer.onSubscribe(relay)
liveData.observeForever(relay)
}
private inner class RemoveObserverInMainThread(private val observer: io.reactivex.Observer<in T>)
: MainThreadDisposable(), Observer<T> {
override fun onChanged(t: T?) {
if (!isDisposed) {
if (t == null) {
if (valueIfNull != null) {
observer.onNext(valueIfNull)
} else {
observer.onError(
ReactiveStreamNullElementException(
"convert liveData value t to RxJava onNext(t), t cannot be null")
)
}
} else {
observer.onNext(t)
}
}
}
override fun onDispose() {
liveData.removeObserver(this)
}
}
}
