访问嵌套的JSON Android [英] Access Nested JSON Android
本文介绍了访问嵌套的JSON Android的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想知道如何在Android中访问此JSON的值:
{
"dados": [{
"Id": 3,
"IdChamado": 3,
"Chamado": "value",
"Solicitante": "value",
"Acao": "",
"ItemDeCatalogo": "Mobile | Instalação",
"InicioPrevisto": "06/01/2017 08:11:00",
"TerminoPrevisto": "06/01/2017 08:22:00"
}, {
"Id": 4,
"IdChamado": 4,
"Chamado": "value",
"Solicitante": "value",
"Acao": "",
"ItemDeCatalogo": "value",
"InicioPrevisto": "06/01/2017 08:11:34",
"TerminoPrevisto": "06/01/2017 08:11:34"
}],
"success": true,
"erroAplicacao": false
}
例如,我需要访问值"IdChamado","chamado","Solicitante".我见过嵌套数组的答案,但是jsonObjects具有实际名称,例如
I need to access the values "IdChamado", "chamado", "Solicitante", for example. I've seen nested arrays answers but with jsonObjects having an actual name, like this .
PS:对不起,我忘了发布代码了:
PS: I'm sorry I forgot to post my codes:
//Method called when the doInBack is complete
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
try {
JSONObject jsonObject = new JSONObject(result);
JSONArray jArray = jsonObject.getJSONArray("dados");
Log.i("***2nd JSON ITSELF***", result);
for (int i=0; i<jArray.length(); i++) {
JSONObject jsonPart = jArray.getJSONObject(i);
int id = jsonPart.getInt("id");
Log.i("***id***", String.valueOf(id));
String chamado = jsonPart.getString("Chamado");
Log.i("***Chamado***", chamado);
String solicitante = jsonPart.getString("solicitante");
Log.i("***Solicitante***", solicitante);
String itemDeCatalogo = jsonPart.getString("itemDeCatalogo");
Log.i("***Item de Catalogo***", itemDeCatalogo);
}
}catch(JSONException e) {
e.printStackTrace();
}// END CATCH
}// END POST EXECUTE
[已解决]:非常感谢您,这就是我喜欢编码的原因(不要害怕问愚蠢的问题).与您作为答案发送的代码配合使用,效果都很好.我以为会更复杂. xD
[SOLVED]: Thank you so much people, you are the reason I like to code (Not be afraid of asking stupid questions). It all worked well with the codes you sent as answer. I thought it would be more complicated. xD
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
try {
JSONObject jsonobject = new JSONObject(result);
JSONArray jsonarray = jsonobject.getJSONArray("dados");
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jobject = jsonarray.getJSONObject(i);
String idChamado = jobject.getString("IdChamado");
String solicitante = jobject.getString("Solicitante");
Log.i("**id**", idChamado);
Log.i("**solicitante**", solicitante);
}
}catch(JSONException e) {
e.printStackTrace();
}// END CATCH
}// END POST EXECUTE
推荐答案
JSONObject jsonobject = new JSONObject("your JSON String here");
JSONArray jsonarray = jsonobject.getJSONArray("dados");
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jsonobject = jsonarray.getJSONObject(i);
String IdChamado = jsonobject.getString("IdChamado");
String Solicitante = jsonobject.getString("Solicitante");
}
请尝试这个
