无法解析方法'fromJson(org.json.JSONObject,java.lang.Class <me.myrottentomatoes.Result []>)'

Question

在fromJson方法中,在我的类Result中,我想将JsonObject反序列化为Result类型的ArrayList.

public static ArrayList<Result> fromJson(JSONObject items) {
    ArrayList results = new ArrayList<Result>();
    Gson gson = new Gson();
    return results = gson.fromJson(items, Result[].class);
}

我无法找到此错误的解决方案:

Cannot resolve method 'fromJson(org.json.JSONObject, java.lang.Class<me.myrottentomatoes.Result[]>)'

对我来说,看起来我正在向方法传递正确的参数.请帮忙,谢谢.这是Result类:

public class Result {

@Expose
private Boolean adult;
@SerializedName("backdrop_path")
@Expose
private String backdropPath;
@SerializedName("genre_ids")
@Expose
private List<Integer> genreIds = new ArrayList<Integer>();
@Expose
private Integer id;
@SerializedName("original_language")
@Expose
private String originalLanguage;
@SerializedName("original_title")
@Expose
private String originalTitle;
@Expose
private String overview;
@SerializedName("release_date")
@Expose
private String releaseDate;
@SerializedName("poster_path")
@Expose
private String posterPath;
@Expose
private Double popularity;
@Expose
private String title;
@Expose
private Boolean video;
@SerializedName("vote_average")
@Expose
private Double voteAverage;
@SerializedName("vote_count")
@Expose
private Integer voteCount;

//get's and set's...
//and the method public static ArrayList<Result> fromJson(JSONObject items)

Answer 1

该fromJson方法的第一个参数是com.google.gson.JsonObject,而不是org.json.JSONObject.

请参阅:https://github.com/google/gson/blob/master/UserGuide.md

另外需要注意的是,你的第二个参数应该是ArrayList.class,而不是Result[].class.
