I'm looking for something like an Array, but it needs to store multiple data types. The Oracle Java tutorials says, "An array is a container object that holds a fixed number of values of a single type." So if I can't use an array for multiple types, what do I use?
I've got this code that only adds one marker to the map at a time because it writes over my lat and long values each loop and only passes the last to the onPostExecute. So I will need something like an array to pass multiple forms of contact info. ie I'm pulling the location from each JSON string, but I need to pull and pass the name & phone number too to the UI from this background thread.
try {
String apples = endpoint.listContactInfo().execute().toString();
JSONObject jObject = new JSONObject(apples);
JSONArray jsonArr = jObject.getJSONArray("items");
for(int i =0 ; i<jsonArr.length() ;i++ ){
JSONObject jsonObj1 = jsonArr.getJSONObject(i);
// Storing each json item in variable
String id = jsonObj1.getString(TAG_ID);
String nameFirst1 = jsonObj1.getString(TAG_FIRSTNAME);
String nameLast1 = jsonObj1.getString(TAG_LASTNAME);
String emailAddress1 = jsonObj1.getString(TAG_EMAIL);
String streetAddress1 = jsonObj1.getString(TAG_ADDRESS);
String phone1 = jsonObj1.getString(TAG_PHONE);
//test to see if made it to string
Log.d("YOUR_TAG", "First Name: " + nameFirst1 + " Last Name: " + nameLast1);
address = coder.getFromLocationName(streetAddress1,5);
Address location1 = address.get(0);
// SET LAT LNG VALUES FOR MARKER POINT
lati = location1.getLatitude();
longi = location1.getLongitude();
Log.d("Location", "Location:" + lati + " " + longi);
}
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return (long) 0;
}
// ADD MARKER TO MAP UI
protected void onPostExecute(Long result) {
mMap.addMarker(new MarkerOptions()
.position(new LatLng(lati, longi))
.title("Hello world"));
}
You can use an ArrayList
.
ArrayList<Object> listOfObjects = new ArrayList<Object>();
And then add items to it.
listOfObjects.add("1");
listOfObjects.add(someObject);
Or create your own object that encapsulates all the field that you require like
public class LocationData {
private double lat;
private double longitude;
public LocationData(double lat, double longitude) {
this.lat = lat;
this.longitude = longitude;
}
//getters
//setters
}
and then add your lat/long pairs to an ArrayList
of type LocationData
ArrayList<LocationData> listOfObjects = new ArrayList<LocationData>();
listOfObjects.add(new LocationData(lat, longitude));
