Our team decide to use Retrofit 2.0 and I'm doing some initial research on this library. As stated in the title, I want parse some nested JSON objects via Retrofit 2.0 in our Android app.
For example, here is a nested JSON object with the format:
{ "title": "Recent Uploads tagged android", "link": "https://www.flickr.com/photos/tags/android/", "description": "", "modified": "2015-10-05T05:30:01Z", "generator": "https://www.flickr.com/", "items": [ { "title": ... "link": ... "media": {"m":"This is the value I want to get:)"} "description": ... "published": ... "author": ... "author_id": ... "tags": ... }, {...}, ... ] }
I'm interested in the JSON objects inside items
array. I notice there are some posts about parsing nested JSON objects via Retrofit 1.X, but the latest Retrofit 2.0 APIs has changed a lot, which is confusing when adapting them to the new APIs.
Two possible solutions come into my mind:
StringConverter
. (I might be wrong~)Update: We can actually get the raw response by setting JSONElement
as the pojo for the HTTP API interface and use GSONConverter provided by Retrofit as the converter.
Convert to DataFrameAdd the JSON string as a collection type and pass it as an input to spark. createDataset. This converts it to a DataFrame. The JSON reader infers the schema automatically from the JSON string.
Objects can be nested inside other objects. Each nested object must have a unique access path. The same field name can occur in nested objects in the same document.
Assuming your complete JSON looks like
{ "title": "Recent Uploads tagged android", "link": "https://www.flickr.com/photos/tags/android/", "description": "", "modified": "2015-10-05T05:30:01Z", "generator": "https://www.flickr.com/", "items": [ { "member1": "memeber value", "member2": "member value" }, { "member1": "memeber value", "member2": "member value" } ] }
So Pojo classes would be
public class MainPojo { private String title; private String description; private String link; private String generator; private String modified; private ArrayList<Items> items; // Getters setters } public class Items { private String member2; private String member1; // Getters setters }
Note : This is similar solution for your JSON. Members of Items.java can be changed if JSON has other keys.
Update for Pojo as new JSON
public class Items { private String tags; private String author; private String title; private String description; private String link; private String author_id; private String published; private Media media; // Getters and Setters } public class Media { private String m; // Getters and Setters }
