Question

我目前已连接到Spotify sdk，我目前正在寻找能够让用户搜索曲目并且它将返回曲目编号。我已经按照sdk指南跟踪一首歌，我得到了响应作为JSON响应，但是当我尝试从我得到的字符串响应在android中创建一个JSONArray时，它告诉我它无法创建JSONArray。我目前得到的回应是这样的

我的android代码看起来像这样

 try {
            response = httpClient.execute(httpPost);
            responseBody = EntityUtils.toString(response.getEntity());
            try {
                jsonArray = new JSONArray(responseBody);
            } catch (JSONException e) {
                e.printStackTrace();
            }

提前感谢您的帮助〜Rockyfish

Answer 1

这样做

JSONObject jObj;
try {
        jObj = new JSONObject(responseBody);
    } catch (JSONException e) {
        e.printStackTrace();
    }

Spotify Android SDK搜索曲目编号
