我已经找到了一些答案,但我不确定为什么我的确失败了......

代码看起来像这样

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        String json = EntityUtils.toString(httpEntity);

        //Convert to JsonArray
        JSONArray jsonArray = new JSONArray(json);

        Log.i(DEBUG_TAG, Integer.toString(jsonArray.length()));

        for (int i = 0; i < jsonArray.length(); i++) {
            JSONObject jsonObject = jsonArray.getJSONObject(i);
            Log.i(DEBUG_TAG, jsonObject.getString(KEY_ID));

            // creating new HashMap
            HashMap<String, String> map = new HashMap<String, String>();
            // adding each child node to HashMap key => value
            map.put(KEY_ID, jsonObject.getString(KEY_ID));
            map.put(KEY_TITLE, jsonObject.getString(KEY_TITLE));
            map.put(KEY_ARTIST, jsonObject.getString(KEY_ARTIST));
            map.put(KEY_DURATION, jsonObject.getString(KEY_DURATION));
            map.put(KEY_VOTECOUNT, jsonObject.getString(KEY_VOTECOUNT));
            map.put(KEY_THUMB_URL, jsonObject.getString(KEY_THUMB_URL));
            map.put(KEY_GENRE, jsonObject.getString(KEY_GENRE));

            //Adding map to ArrayList
            if …
