json中有多个不同的嵌套对象以进行改进

Question

我的json图片，请点击1和2 。 希望可以理解。

故事：我想读一次Json页面。 没关系，我对此没有问题。我只能读取第一个单元格中的数据。 其他类中的其他单元格。 而且我通过使用http://www.jsonschema2pojo.org/具有所有类！重要！ 每个不同的类型都包含不同的对象命名列表。

但是，如何通过改型库将每个单元格中的数据分配到不同的类？

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 + '\'' + 
        "}";
    }

Answer 1

可以对同一级别的对象的不同命名进行解析。 可以通过一种方式定义@SerializedName(value="name1", alternate={"name2", "name3"}) String b; 含义定义对象的备用名称。 但是请注意，此对象需要具有相同的数据。 在您的情况下，它将在所有情况下解析“ id”和“ name” ，因为json在所有情况下均包含这两个字段。

另一方面，当您想解析所有字段时，最好使用自定义JsonDeserializer 。 您可以在此处找到如何为GSON库编写自己的反序列化器的示例： Deserializer

Answer 2

Okey我做到了，这是我的解决方案。 而且有效。
