json 中多个不同的嵌套对象进行改造

Question

我的json图，请点击1 和 2。 希望足够理解。

故事： 我想读一遍 Json 页。没关系，我没问题 this.I 只能读取第一个单元格中的数据。不同类中的其他单元格。而且我还通过使用 http://www.jsonschema2pojo.org/ 获得了所有类 重要！！每个不同的类型，包含不同的命名对象列表。

但是如何通过改造库将每个单元格中的数据设置为不同的类？

public class FeaturedList{
  //this my main class
@SerializedName("featured")
private List<FeaturedItem> featured;

@SerializedName("type")
private String type;

@SerializedName("title")
private String title;

public void setFeatured(List<FeaturedItem> featured){
    this.featured = featured;
}

public List<FeaturedItem> getFeatured(){
    return featured;
}

public void setType(String type){
    this.type = type;
}

public String getType(){
    return type;
}

public void setTitle(String title){
    this.title = title;
}

public String getTitle(){
    return title;
}

@Override
public String toString(){
    return 
        "FeaturedList{" + 
        "featured = '" + featured + '\'' + 
        ",type = '" + type + '\'' + 
        ",title = '" + title + '\'' + 
        "}";
    }

     restInsterface = ApiClient.getClient().create(RestInsterface.class);
    Call<List<FeaturedList>> listCall;
    listCall=restInsterface.getFeaturedList();
    listCall.enqueue(new Callback<List<FeaturedList>>() {
        @Override
        public void onResponse(Call<List<FeaturedList>> call, Response<List<FeaturedList>> response) {
            for (FeaturedList item:response.body()){
                Log.i(TAG, "onResponse: "+item.toString());
            }
        }

        @Override
        public void onFailure(Call<List<FeaturedList>> call, Throwable t) {

        }
    });
      }

Answer 1

可以解析同一级别对象的不同命名。一种方式是可以定义 @SerializedName(value="name1", alternate={"name2", "name3"}) String b; 意思是定义对象的备用名称。但要小心这个对象需要有相同的数据。在您的情况下，它将在所有情况下解析 "id"、"name"，因为 json 包含这两个字段在所有情况下。

另一方面，当您想要解析所有字段时，最好使用自定义 JsonDeserializer。您可以在此处找到如何为 GSON 库编写自己的解串器的示例：Deserializer

Okey I did, this is my solution. and it works.

 public class DataList{

@SerializedName("featured")
private List<FeaturedItem> featured;
@SerializedName("products")
private List<ProductsItem> products;
@SerializedName("categories")
private List<CategoriesItem> categories;

private List<CollectionsItem> collections;
@SerializedName("shops")
private List<ShopsItem> shops;

private String type;

@SerializedName("title")
private String title;

public List<FeaturedItem> getFeatured() {
    return featured;
}

    return products;
}
