Question

（对不起，我是我的英语，我不是母语人士）。添加：我已经直接通过网络编辑了json。对于要更改的元素，有时是字符串“”，有时是数组[]，为空或完整。我已经尝试过使用List，String，ArrayList和Array []，但它始终有一个错误（但不在同一位置）。这是失败的方法的代码：

   @Override
   protected void LoadingNews() {
     this.mDisposable = NewsStreams.MostPopularStream(0)
     .subscribeWith(new DisposableObserver<MostPopularStructure>(){
        @Override
        public void onNext(MostPopularStructure mostPopularStructure) {
               mMostPopularResults = mostPopularStructure.getResults();
               UpdateRecyclerView();
               mNewsAdapter.notifyDataSetChanged();
               }
        @Override
        public void onError(Throwable e) {
               Log.e("News","MostPopular.LoadingNews : Error : " + e.getMessage());
               }
        @Override
        public void onComplete() {
        }
    });
}

这是MostPopularStructure的摘录：

public class MostPopularStructure {

@SerializedName("status")
@Expose
private String status;
@SerializedName("copyright")
@Expose
private String copyright;
@SerializedName("num_results")
@Expose
private Integer numResults;
@SerializedName("results")
@Expose
private List<MostPopularResult> results = null;

public String getStatus() {
    return status;
}

public void setStatus(String status) {
    this.status = status;
} …

…和类MostPopularResult哪里出了问题：

public class MostPopularResult {

    @SerializedName("url")
    @Expose
    private String url;
    …
    @SerializedName("des_facet")
    @Expose
    private List<String> desFacet = null;
    **@SerializedName("org_facet")
    @Expose
    private List<String> orgFacet = null;**
    @SerializedName("per_facet")
    @Expose
    private List<String> perFacet = null;
    @SerializedName("geo_facet")
    @Expose
    private List<String> geoFacet = null;
    @SerializedName("media")
    @Expose
    private List<Medium> media = null;

    public String getUrl() {
        return url;
    } …

以及List试用期间的错误消息：

E/News: MostPopular.LoadingNews : Error : java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 1 column 822 path $.results[0].org_facet

String试用期间的错误消息（我已将orgfacet的类型更改为String）：

E/News: MostPopular.LoadingNews : Error : java.lang.IllegalStateException: Expected a string but was BEGIN_ARRAY at line 1 column 3786 path $.results[1].org_facet

对于使用ArrayList和Array []类型的试验，我有与第一次试验相同的信息。

紧随其后的是json（这只是节选，原始内容包含62,000个字符以上！）：

感谢您的帮助和/或建议。

Answer 1

您可以更改“最受欢迎”结构以仅保留所需的数据，因此您应该从其中删除所有％-facet。
