Question

我试图将json字符串解析为JSONArray元素，但是当我尝试我得到＆＃34;无法转换为JSONArray＆＃34;

我的字符串是这样的（但更长）：

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

我真的不在乎＆＃34; mylist＆＃34;或者＆＃34; myinfo＆＃34;部分，只是＆＃34;动漫＆＃34;部分是必要的。大约有1000个项目。

我已经验证了我的JSON，它是有效的。

这是我的代码：

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

这是我的问题开始的地方。我也试过这个：

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

和 JSONObject object = new JSONObject（replacementString）; JSONArray replacementResponse = object.getJSONArray（＆＃34; anime＆＃34;）;

有类似的结果

我在这里看不到什么？提前谢谢！

请遵循此代码。

    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();
    }
