Я хочу получить изображение объекта JSON в информации JSONObject. Но каков наилучший способ сделать это?

Что я сделал до сих пор:

String json = download(url); 

    try { 
     JSONObject result = new JSONObject(json); 
     JSONArray results = result.getJSONArray("movies"); 

     for(int i = 0; i < results.length(); i++) 
     { 
      JSONObject movieObject = results.getJSONObject(i); 
      CouchPotatoMovie movie = new CouchPotatoMovie(movieObject); 
      movies.add(movie); 
     }

Так изображения должны быть в объекте CouchPotatoMovie. Но я не уверен, как их вытащить.

Вы можете быть более точным, какие образы вы хотите найти? – Pshemo

Я хочу получить URL-адреса с плаката, extra_thimbs, poster_original и landscape. Но я не уверен, как их получить – Timmeeh93

@ Timmeeh93 '> result.getJSONArray (" movies ")'. В JSON, который вы опубликовали, нет никаких ключей с именем ** movies **. – fardjad

Создать JSONObject из строки JSON:

JSONObject jsonObject = new JSONObject(jsonString);

и использовать getJSONObject() метод:

JSONObject imagesJsonObject = jsonObject.getJSONObject("info").getJSONObject("images");

Затем, вы можете получить ключи с помощью keys() и использовать getJSONArray() и getString() методы, чтобы получить URL изображения.

Пример:

Чтобы получить URL-адреса из poster:

JSONArray posterJsonArray = imagesJsonObject.getJSONArray("poster"); 
List<String> urls = new ArrayList<String>(); 
for (int i = 0; i < posterJsonArray.length(); i++) { 
    String url = posterJsonArray.getString(i); 
    urls.add(url); 
}

@Pshhemo, жаль, что я новый для stackoverflow, поэтому я не совсем уверен, как его использовать. Но я редактировал мой пост выше. – Timmeeh93

Спасибо большое! :) – Timmeeh93
