Question

JSONArray cities = json.getJSONArray("city");

With the above code got the following output:

{
"id":"1",
"name":"London"
"country":"United Kingdom"
},

{
"id":"2",
"name":"Madrid"
"country":"Spain"
},

{"id":"3",
"name":"Paris"
"country":"France"
},

{
"id":"3",
"name":"Zurich"
"country":"Switzerland"
}

How can I get only the name from the JSON array to a string array?

e.g.: String[] s ={"London","Madrid","Paris","Zurich"}

Answer 1

Loop through the JSONArray and pull out the "name" fields. This is done similarly to your json.getJSONArray("city"); call, only in a loop:

JSONArray cities = json.getJSONArray("city");
JSONObject city = null;
String[] s = new String[cities.length()];

for (int i = 0; i < cities.length(); i++)
{
    city = cities.getJsonObject(i);
    s[i] = city.get("name");
}
