我认为它与线程有关，但我找不到解决方法。

class MovieDetailViewModel(application: Application) : BaseViewModel(application) {
    private val movieAPIService = MovieAPIService()
    private val disposable = CompositeDisposable()
    val oneMovie = MutableLiveData<Movie>()

    fun loadData(id: Int){
        getMovie(id)
    }

    private fun getMovie(id: Int) {
        println(id)
        disposable.add(movieAPIService.getMovie(id)
            .observeOn(Schedulers.io())
            .subscribeOn(AndroidSchedulers.mainThread())
            .subscribeWith(object : DisposableObserver<FirstModel2>(){
                override fun onComplete() {

                }

                override fun onNext(t: FirstModel2) {
                    val movie : OneMovie = t.data
                    oneMovie.value = movie.movie
                }

                override fun onError(e: Throwable) {
                    e.printStackTrace()
                }

            }))
    }
}

我在第一个fragment中使用api在recyclerview中显示电影，当我点击它时，我想切换到第二个fragment并使用id显示电影的详细信息又是电影

Answer 1

您在 observeOn 和 subscribeOn 中混合了调度程序。交换它们。
