java - Simpleadapter(带有子项的 JSON)

Question

我是 Android 开发新手，我花了几天时间尝试让我的应用程序运行，但没有成功。我正在使用 AsyncTask 和 SimpleAdapter，它返回数据，但是我的 JSON 有子项。它是注释的 JSON，有时注释中包含该注释的答案。但我不知道是否在 listView 中执行 listView 。我真的迷路了，我搜索了很多，但没有找到任何关于我的问题的信息。

遵循JSON:

在 protected Void doInBackground(Void...arg0) 内的 AsyncTask 中，我以这种方式进行 JSON 调用:

    JSONArray comentarios = jsonObj.getJSONArray("COMENTARIOS");
    for (int i = 0; i < comentarios.length(); i++) {
      JSONObject c = comentarios.getJSONObject(i);
      String nome = c.getString("nome");
      String comentario = c.getString("comentario");

      HashMap<String, String> comentariotxt = new HashMap<>();

      comentariotxt.put("nome", nome);
      comentariotxt.put("comentario", comentario);

      JSONArray resp = c.getJSONArray("resp");
      if(resp.length() > 0){
          for (int j = 0; j < resp.length(); j++){
              JSONObject d = resp.getJSONObject(j);
              String respostaNome = d.getString("nome");
              String respostaComentario = d.getString("comentario");
              Log.d("respostaNome",respostaNome);

              HashMap<String, String> respostatxt = new HashMap<>();
              respostatxt.put("respostaNome", respostaNome);
              respostatxt.put("respostaComentario", respostaComentario);
              comentarioList.add(respostatxt);
          }
      }
      comentarioList.add(comentariotxt);
  }

但这里已经把一切搞乱了。嗯，我需要两件事。让他们按顺序提出评论和答案，气球响应的外观将与评论气球不同。目前我只做评论的 ListView ，但我也不确定是否需要另一个 ListView 来获取答案。我的意思是……我很失落!有人帮助我吗？

非常感谢你们!

我尝试使用单个对象修改您的json。

请检查以下代码来解析此json:

  try {
        JSONObject jsonObject1 = new JSONObject("{\n" +
                "\t\"COMENTARIOS\": [{\n" +
                "\t\t\"comentarios_id\": \"1053939\",\n" +
                "\t\t\"noticias_id\": \"284901\",\n" +
                "\t\t\"duelos_id\": \"0\",\n" +
                "\t\t\"respostas_id\": \"0\",\n" +
                "\t\t\"videos_id\": \"0\",\n" +
                "\t\t\"nome\": \"ludi\",\n" +
                "\t\t\"email\": \"email@email.com.br\",\n" +
                "\t\t\"ip\": \"186.212.2.226\",\n" +
                "\t\t\"comentario\": \"COMENTÁRIO\",\n" +
                "\t\t\"data_cadastro\": \"2018-04-03 09:34:00\",\n" +
                "\t\t\"status\": \"3\",\n" +
                "\t\t\"gostei\": \"67\",\n" +
                "\t\t\"naogostei\": \"143\",\n" +
                "\t\t\"resp\": []\n" +
                "\t}]\n" +
                "}");
        JSONArray jsonArray = jsonObject1.getJSONArray("COMENTARIOS");
        for (int i = 0; i < jsonArray.length(); i++) {
            JSONObject jsonObject = jsonArray.getJSONObject(i);
            String comentarios_id = jsonObject.get("noticias_id").toString();
            System.out.println("----comentarios_id---" + comentarios_id);
        }

    } catch (JSONException e) {
        e.printStackTrace();
        System.out.println("----comentarios_id---exc--" + e);
    }

注意: 在我传递静态 json 的 json 对象中，您需要传递存储所有 json 的您自己的字符串。
