I created an new AsyncTask and everything seems to be running fine. I just do not know how to retrieve the results and utilize them in the Fragment that is creating the AsyncTask.
How can I retrieve an ArrayList after the AsyncTask has finished running and use that ArrayList in the calling fragment? Is it within the OnPostExecute?
ASYNCTASK
@Override
protected ArrayList<String> doInBackground(String... params) {
// TODO Auto-generated method stub
mArray = new ArrayList<String>();
StringBuilder sb = new StringBuilder(GEOCODING_API_BASE + OUT_JSON);
try {
sb.append("?address=")
.append(URLEncoder.encode(params[0], "UTF-8"));
sb.append("&sensor=false");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String uri = sb.toString();
HttpGet httpGet = new HttpGet(uri);
HttpClient client = new DefaultHttpClient();
HttpResponse response;
StringBuilder stringBuilder = new StringBuilder();
try {
response = client.execute(httpGet);
HttpEntity entity = response.getEntity();
InputStream stream = entity.getContent();
int b;
while ((b = stream.read()) != -1) {
stringBuilder.append((char) b);
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
JSONObject jsonObject = new JSONObject();
try {
jsonObject = new JSONObject(stringBuilder.toString());
double lng = ((JSONArray) jsonObject.get("results"))
.getJSONObject(0).getJSONObject("geometry")
.getJSONObject("location").getDouble("lng");
double lat = ((JSONArray) jsonObject.get("results"))
.getJSONObject(0).getJSONObject("geometry")
.getJSONObject("location").getDouble("lat");
Log.e("latitude", "" + lat);
Log.e("longitude", "" + lng);
String longitude = Double.toString(lng);
String latitude = Double.toString(lat);
mArray.add(longitude);
mArray.add(latitude);
} catch (JSONException e) {
e.printStackTrace();
}
return mArray;
}
@Override
protected void onPostExecute(ArrayList<String> result) {
super.onPostExecute(result);
}
}
CALLING FRAGMENT
case R.id.btnSubmit:
String desc = etDesc.getText().toString().trim();
String loc = etLocation.getText().toString().trim();
String time = btnTime.getText().toString().trim();
String date = btnDate.getText().toString().trim();
String sport = tvSportName.getText().toString().trim();
String title = etTitle.getText().toString().trim();
ParseUser currentUser = ParseUser.getCurrentUser();
// check to see if the values are empty
SportEvent newSportEvent = new SportEvent();
newSportEvent.setSport(sport);
newSportEvent.setTime(title);
newSportEvent.setDate(date);
newSportEvent.setTitle(title);
newSportEvent.setDesc(desc);
newSportEvent.setUser(currentUser);
//getLatLongFromAddress(loc);
new LocationAsyncTask().execute(loc);
// implement user signin first>>>
// newSportEvent.setUser(ParseUser.getCurrentUser());
ParseACL acl = new ParseACL();
acl.setPublicReadAccess(true);
acl.setPublicWriteAccess(true); // objects created are writable
newSportEvent.setACL(acl);
