將JSON字符串解析為JSONArray（Android）

Question

我正在嘗試將json字符串解析為JSONArray元素，但是當我嘗試時，我得到“無法轉換為JSONArray”

我的字符串是這種方式（但更長）：

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

我並不在乎“ mylist”或“ myinfo”部分，只需要“ anime”部分。 大約有1000個項目。

我已經驗證了JSON，它是有效的。

這是我的代碼：

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

這是我的問題開始的地方。 我也嘗試過這個：

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

和JSONObject object = new JSONObject（replacedString）; JSONArray替換了Response = object.getJSONArray（“ anime”）;

結果相似

我在這里沒看到什么？ 提前致謝！

請遵循此代碼。

    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();
    }
