create an array of all the keys in a JSONObject Android

Question

Hi im wanting to create an array of all the keys in a JSONObject. my understanding (please correct me if i'm wrong) is that i need to convert the JSONObject to a Map and then create an Array from this does anyone know how to do this?

Answer 1

No need to convert JSONObject to a Map and then create an Array of keys just use JSONObject.names() for getting all keys in an JsonArray then convert it to Array or ArrayList. example:

JSONObject  json = new JSONObject("json object string");
JSONArray namearray=json.names();  //<<< get all keys in JSONArray
