我是Android开发的新手，我正在尝试几天让我的应用程序正常工作但没有成功。
我正在使用AsyncTask和SimpleAdapter，它会返回数据，但我的JSON包含子项。这是JSON条评论，评论中有时会有评论的答案。但我不知道我是否在listView内进行了listView。我真的迷路了，我搜索了很多，但我没有发现任何关于我的问题。
按照 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);
}
但是这里已经把一切搞得一团糟了。好吧，我需要两件事。让他们按顺序带来评论和答案，气球响应的外观将与评论气球不同。目前我只是对评论进行列表浏览，但我也不确定是否需要另一个列表视图来获得答案。我的意思是......我很失落！有人帮帮我吗？
非常感谢你们！
答案 0 :(得分：1)
我尝试用单个对象修改 json 。
请检查以下代码以解析此 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);
}
Note:在我传递静态json的json对象中，你需要传递你自己的字符串来存储所有的json。
