Get String from json with nested json object and nested json arrays with multiple json object, in Android
Date : March 29 2020, 07:55 AM
this one helps. I need to access as String all the single parameters contained in a complex Json. , I've not tried. But i guess it may work. JSONObject obj = new JSONObject(jsonString);
String id = obj.getString("id");
String error = obj.getString("error");
JSONObject result = obj.getJSONObject("result");
int nPeople = result.getInt("nPeople");
JSONArray people = result.getJSONArray("people");
for(int i = 0 ; i < people.length() ; i++){
JSONObject p = (JSONObject)people.get(i);
String namePeople = p.getString("namePeople");
...
}

Hope that helps Try like this. JSON is string.Directly javascript's length property will not works.You have convert it to object first using JSON.parse(). json ='{"results":[{"eventName":"Rey","name":"Tar","dateOfShow":"2017-01-27T22:00:00","userGroupName":"Bit","eventHallName":"Grnn","imageSource":"test2.jpg"},{"eventName":"Gor","name":"Skum","dateOfShow":"2017-01-30T20:00:00","userGroupName":"Gaf","eventHallName":"Gai","imageSource":"test1.jpg"}]}';
res = JSON.parse(json)
alert(res.results.length);

Dine Restaurant","phone":9512556799},"-LZn4vGB7v0frlDywQ1x":
