我是Android / RX领域的新手，我正在制作一个使用MVVM架构在Kotlin中使用TMDB API的应用程序。
我的数据模型是：
data class Credits ( val credits: MutableList<Details>)
data class Details(@SerializedName("genres") val genres: MutableList<GenresResults>,
@SerializedName("overview") val overview: String,
@SerializedName("credits") val credits1: MutableList<CreditsResults>,
@SerializedName("title") val title: String,
@SerializedName("vote_average") val vote_average: Double,
@SerializedName("backdrop_path") val backdrop: String,
@SerializedName("id") val id: String)
包含get方法的数据接口是：
interface TMDBApiMovieDetails {
@GET("movie/{id}")
fun getDetails(@Path("id") id: Int,
@Query("language") language: String,
@Query("append_to_response") credits: String,
@Query("api_key") api_key: String)
: Observable<Details>
companion object {
fun create(): TMDBApiMovieDetails {
val retrofit = Retrofit.Builder()
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create()).baseUrl("https://api.themoviedb.org/3/")
.build()
return retrofit.create(TMDBApiMovieDetails::class.java)
}
}
在ViewModel中，我使用以下代码：
class MovieDetailsViewModel( val tmdbApiMovieDetails: TMDBApiMovieDetails)
{
private val refreshSubject: PublishSubject<Unit> = PublishSubject.create()
private val basicApiCall: ConnectableObservable<MutableList<Details>>
private val compositeDisposable = CompositeDisposable()
init {
basicApiCall = refreshSubject
.flatMap { return@flatMap tmdbApiMovieDetails.getDetails(id, "en-US","credits", api_key)
.map { it.credits}
.subscribeOn(Schedulers.io())}
.publish()
compositeDisposable.add(basicApiCall.connect())
}
fun getPopularMoviesRefreshObserver() : Observer<Unit> {
return refreshSubject
}
fun getPopularMoviesRetrievedObservable() : Observable<MutableList<Details> {
return basicApiCall
}
最后，在相关活动（查看）中，我将其用于将结果传递到handleResponse()，它将填充相关的文本和图像字段。
presenter1.getPopularMoviesRefreshObserver().onNext(Unit)
disposable = presenter1.getPopularMoviesRetrievedObservable()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe { handleResponse(it) }
问题是我遇到gson错误，提示：
期望BEGIN_ARRAY但在第1行1372列上为BEGIN_OBJECT
我知道这是指错误的数据模型定义，但我不知道如何正确定义它...
用简单的话来说，我想要的是Details数据类的内容是可引用的，以便我可以使用它们来填充我的details活动。
任何建议？
