I\'m trying to read JSON from string (obtained from web), but it returns null
.
Specifically, result.append(name + id);
gives me nulln
"id" and "name" are inside the JSON object against the key "rikeard". So you need to make changes like following:
JSONParser parser = new JSONParser();
try {
Object obj = parser.parse(datJ);
JSONObject jsonObject = (JSONObject) obj;
JSONObject rikeardObject = (JSONObject) obj.get("rikeard");
String name = (String) rikeardObject.get("name");
Integer id = (Integer) rikeardObject.get("id");
result.append(name + id);
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (org.json.simple.parser.ParseException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Use this method it's work for me,
private void extractJson(){
String jsonString="{\"rikeard\":{\"id\":2828822,\"name\":\"Rikeard\",\"profileIconId\":688,\"summonerLevel\":30,\"revisionDate\":1422917445000}}";
try {
JSONObject jsonObject=new JSONObject(jsonString);
if(jsonObject!=null){
jsonObject=jsonObject.optJSONObject("rikeard");
if(jsonObject!=null){
String id=jsonObject.optString("id");
Log.d("MainActivity","id="+id);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
Try this:
JSONParser parser = new JSONParser();
try {
Object obj = parser.parse(datJ);
JSONObject jsonObject = (JSONObject) obj;
JSONObject rikeardObject = (JSONObject) jsonObject.get("rikeard");;
String name = (String) rikeardObject .get("name");
Integer id = (Integer) rikeardObject .get("id");
result.append(name + id);
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (org.json.simple.parser.ParseException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
