Simpleadapter（带有子项的JSON）

Question

I'm new to Android development, and I'm trying for several days to make my app work but with no success. I'm using AsyncTask and SimpleAdapter , it returns the data however my JSON has sub items. It's a JSON of comments where sometimes in a comment has the answers of that comment. But I have no idea if I do a listView inside a listView . I'm really lost, I searched a lot and I did not find anything about my problem.

Follow the JSON :

}

In AsyncTask inside the protected Void doInBackground(Void... arg0) I make the JSON call this way:

    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);
  }

But here it already messes everything up. Well, I need two things. Let them bring the comment and the answers in order and the appearance of the balloon responses will be different from the comment balloon. At the moment I'm only doing a listview of the comments, but I'm also not sure if I need another listview for the answers. I mean ... I'm very lost! Someone help me?

Thank you so much guys!

I tried to modify your json with single object.

Please check the below code to parse this 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);
    }

Note: In json object where i am passing static json, you need to pass your own string where all the json is stored.
