Get nested JSON object from a JSON Array - arrays

Question

May i know how to get JSON object from an json array??
JSON:
[
{
"id": 1,
"user": {
"id": 20710,
"username": "abc",
"first_name": "",
"last_name": "",
},
"action": {
"name": "xxx",
"date": 19/01/01,
},
},
{
"id": 2,
"user": {
"username": "xyx",
"first_name": "xxx",
"last_name": "yyy",
},
"action": {
"name": "xxx",
"date": 19/05/01,
},
},]
I want to get username of these users in a list, but i cant get the value when i get this json from api as JSONArray.
My code:
public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
Log.d("Create Response", response.toString());
ArrayList<String> list = new ArrayList<String>();
JSONArray jsonArray = response;
try {
if (jsonArray != null) {
int len = jsonArray.length();
for (int i=0;i<len;i++){
JSONObject c=response.getJSONObject(1);
String id = c.getString(i);
HashMap<String, String> map = new HashMap<String, String>();
map.put("id", id);
feeds_List.add(map);
}
}
I cannot use
JSONObject object=JsonArray.getJSONObject("user");
here,
it only accept int for getJSONObject("user"); if it is JSONArray

You can use like this also.Suppose response String is userInfo
ArrayList<String> usernames = new ArrayList<String>();
JSONArray userList = new JSONArray(userInfo);
for (int j = 0; j < userList.length(); j++) {
JSONObject userObject = new JSONObject(userList.getString(j));
String user = userObject.getString("user");
JSONObject usernameInfo = new JSONObject(user);
usernames.add(usernameInfo.getString("username"));
}
Try this, if not working please mention me in comment.
