android - 如何使用 Retrofit 解析嵌套的 json ....？

Question

我不知道如何使用改造解析 json。熟悉使用 Retrofit 解析简单的 json，但不熟悉使用 Retrofit 解析 nested Json。

这是我的 Json 数据......................

  {
         "current_observation": {
             "image": {
                 "url":"http://icons.wxug.com/graphics/wu2/logo_130x80.png",                
                 "title":"Weather Underground",
                 "link":"http://www.wunderground.com"
},
                  {
                  "url":"http://icons.wxug.com/graphics/wu2/logo_130x80.png",               
                 "title":"Weather Underground",
                 "link":"http://www.wunderground.com"
                   }
             }
         }
     }

任何帮助将不胜感激。谢谢。

这是我的简单json方法

public class Country {
    @SerializedName("current_observation")
    @Expose
    private List<Items> items;

    public List<Items> getItems() {
        return items;
    }

    public void setItems (List<Items> items) {
       this.items = items;
    }
}

来了.....

 public class Items {
        @SerializedName("image")
        @Expose
        private String url;
        private String title;
        private String link;

        public String getFlag() {
            return url;
        }
        public String getRank() {
           return link;
        }
        public void setRank(String link) {
            this.link = link;
        }
        public void setFlag(String url) {
            this.url = url;
        }
        public String getCountryname() {
            return title;
        }
        public void setCountryname(String rating) {
            this.title = rating;
        }
    }

主要 Activity 中的代码

Call <Country>  call = apiInterface.getCountries();

        call.enqueue(new Callback <Country>() {
            @Override
            public void onResponse(Call<Country> call, Response<Country>  response) {
                Log.d(TAG,"onSuccess Server Response "+ response.toString());

                Log.d(TAG,"onSuccess received information "+ response.body().toString());
                List<Items> items = response.body().getItems();
                adapter = new RecAdapter(items, getContext().getApplicationContext());
                recyclerView.setAdapter(adapter);

            }

Answer 1

CurrentObservation.class

public class CurrentObservation {

@SerializedName("image")
@Expose
private Image1 image;

public Image1 getImage() {
return image;
}

public void setImage(Image1 image) {
this.image = image;
}
}

例子.java

public class Example {

@SerializedName("current_observation")
@Expose
private CurrentObservation currentObservation;

public CurrentObservation getCurrentObservation() {
return currentObservation;
}

public void setCurrentObservation(CurrentObservation currentObservation) {
this.currentObservation = currentObservation;
}
}

图片1.java

public class Image1 {

@SerializedName("url")
@Expose
private String url;
@SerializedName("title")
@Expose
private String title;
@SerializedName("link")
@Expose
private String link;

public String getUrl() {
return url;
}

public void setUrl(String url) {
this.url = url;
}

public String getTitle() {
return title;
}

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

public String getLink() {
return link;
}

public void setLink(String link) {
this.link = link;
}

}

在主Activity中调用

  Call<Example> ex = BaseUrlClass.getInterface().ex("whatever parameters");
    ex.enqueue(new Callback<Example>() {
        @Override
        public void onResponse(Call<Example> call, Response<Example> response) {
            Example list = response.body();

            CurrentObservation a = list.getCurrentObservation();
            List<Image1> im = a.getImage();
            for (int i = 0;i<im.size();i++){
                Image1 image1= im.get(i);
                String a = image1.getTitle();
                String b = image1.getUrl();
                String c = image1.getLink();
            }
        }

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

        }
    });

最后在您的界面中

public interface ApiUtils {

@GET("")  //whatever url
Call<Example> ex();  //or any parameter
}
