解析JSON字符串JSONArray（安卓）

问题描述：

我试图JSON字符串解析到一个JSONArray元素，但是当我尝试，我得到“无法转换到JSONArray”解析JSON字符串JSONArray（安卓）

我的字符串是这样（但方式更长）：

{ 
"mylist": { 
    "myinfo": { 
     "user_id": 6225804,

我并不真正关心“mylist”或“myinfo”部分，只需要“动漫”部分。有大约1000件物品。

我验证了我的JSON并且它是有效的。

这是我的代码：

JSONObject object = new JSONObject(replacedString); 
JSONArray replacedResponse = new JSONArray(replacedString);

，这里是我的问题开始的地方。我也试过这样：

JSONObject object = new JSONObject(replacedString); 
JSONArray replacedResponse = object.getJSONArray("mylist");

和的JSONObject对象=新的JSONObject（replacedString）; JSONArray replacedResponse = object.getJSONArray（“anime”）;

类似的结果

我在这里没有看到什么？提前致谢！

MYLIST不是一个数组，它与MyInfo的（对象）和动画（阵列）的对象，...尝试http://www.jsonschema2pojo.org/得到正确的POJO – Fusselchen

我试过也与此： JSONArray replacedResponse = object.getJSONArray（“anime”）; 它抛出：org.json.JSONException：没有值的动画 – emboole

比它应该导致类似于'对象 - > getJsonObject（mylist） - > getJsonArray（动漫）' – Fusselchen

答

请按照此代码。

String stringObj = "[YOUR JSON]"; 

    // first Convert string into JsonObject 
    try { 
     JSONObject jsonObject = new JSONObject(stringObj); 

     // Inside the above object you have "mylist" key and the respective JsonObject so 
     JSONObject myListObject = jsonObject.optJSONObject("mylist"); 

     // Insdide mylist you have myinfo Json and anim JsonArray 
     if(myListObject == null) { 
      return; 
     } 

     JSONObject myinfoObject = myListObject.optJSONObject("myinfo"); 
     JSONArray animeJsonArray = myListObject.optJSONArray("anime"); 

     // check null for myinfoObject and animeJsonArray and do the operation 

    } catch (JSONException e) { 
     e.printStackTrace(); 
    }

我是一个简单的人。我理解这个解释。我复制，粘贴和修改我自己的代码。有用。我将答案标记为正确。 – emboole
