Question

我在Android中获得Jason回复的经验不足。我的问题是如何解析来自此API {J}的JSON。基本上是为了介绍，我需要参加活动。然后我想创建一个匹配列表并从中创建https://api.the-odds-api.com/v2/odds/?sport=UPCOMING&region=uk&apiKey=e3b70c1881a5d9eec34e4cb256844874。

这是我与API沟通的课程

RecyclerView

不知何故，我参加了这些活动，但不知道如何继续这项活动。我需要一些事件，因为我想创建Match.class（String homeTeam，String awayTeam）的任意对象，并将其传递给循环视图。我在这个JsonTask上这样做，我认为这不是最好的方法。private class JsonTask extends AsyncTask<String, String, String> implements OnVisibleCallback{ protected String doInBackground(String... params) { HttpURLConnection connection = null; BufferedReader reader = null; try { URL url = new URL(params[0]); connection = (HttpURLConnection) url.openConnection(); connection.connect(); InputStream stream = connection.getInputStream(); reader = new BufferedReader(new InputStreamReader(stream)); StringBuffer buffer = new StringBuffer(); String line = ""; while ((line = reader.readLine()) != null) { buffer.append(line+"\n"); Log.d("Response: ", "> " + line); //here u ll get whole response...... :-) } return buffer.toString(); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { if (connection != null) { connection.disconnect(); } try { if (reader != null) { reader.close(); } } catch (IOException e) { e.printStackTrace(); } } return null; } @Override protected void onPostExecute(String response) { super.onPostExecute(response); Log.d("json",response); try { JSONObject jObject = new JSONObject(response); String data = jObject.getString("data"); JSONObject objData = new JSONObject(data); String events = objData.getString("events"); JSONObject eventObj = new JSONObject(events); int numberOfEvents = eventObj.length(); List<Match> matchList= Arrays.asList(new Match("Juventus","Fiorentina")); counter = 1; Log.d("Counter_Ticket_Fragment", String.valueOf(counter)); mAdapter = new MatchAdapter(matchList,counter); changeVisible(); mAdapter.setCallback(this); recyclerView.setAdapter(mAdapter); recyclerView.setItemAnimator(new DefaultItemAnimator()); } catch (JSONException e) { e.printStackTrace(); } } @Override public void changeVisible() { if(mAdapter.getItemCount()>0){ noMatch.setVisibility(View.GONE); } else{ noMatch.setVisibility(View.VISIBLE); } } }在JsonTask OnCreateView中被调用。

这是Match.class

Fragment

这是MatchAdapter

   public class Match  {

private String team_home;
private String team_away;



        public Match(String team_home, String team_away){
            this.team_home = team_home;
            this.team_away = team_away;
        }

public String getHomeTeam() {
    return team_home;
}

public String getAwayTeam() {
    return team_away;
}
}

Answer 1

我建议您更改后端json数据，因为数据结构不合理。

创建一个事件数组，其中数组的每个元素都是一个对象，然后使用下面的代码解析数据

       JSONObject jObject = new JSONObject(response);
        String data = jObject.getString("data");
        JSONObject objData = new JSONObject(data);
        String events = objData.getString("events");
       JSONArray jsonEvent = 
                            objData.getJsonArray(events);
       for(int i=0; i<jsonEvent.length; I++){
             JsonObject jsonObj = jsonEvent.getJsonObject(i);
       }

Answer 2

JSONObject jObject = new JSONObject(response);
            String data = jObject.getString("data");
            JSONObject objData = new JSONObject(data);
            String events = objData.getString("events");
            JSONObject eventObj = new JSONObject(events);
            int numberOfEvents = eventObj.length();


            for(int i = 0; i<numberOfEvents; i++){
                event = eventObj.names().getString(i);
                String matchOne = eventObj.getString(event);
                JSONObject singleEventObj = new JSONObject(matchOne);
                JSONArray participants = singleEventObj.getJSONArray("participants");
                }

我确实迭代了事件名称（键），现在一切都按照要求进行了
