I am building an android application where I am using AutoComplete text to show the search of google place name. Now the problem I am facing is if I enter space between 2 words, it stops displaying any results.
For Ex. - On writing the text "new" it will suggest me "new dehli", "new zealand" etc., when I use a space after the word "new", it stops displaying any result. I have tried couple of things along with: - input = input.replaceAll(" ","%20");
After debugging, I checked that the results are coming but they are not adding in my simple list using adapter. But it looks like the simple list adapter is not adding the space character and there by not displaying the result.
Here is the code -
oncreateview -
atvPlaces = (AutoCompleteTextView) findViewById(R.id.atv_places); atvPlaces.setThreshold(1); atvPlaces.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { placesTask = new PlacesTask(); placesTask.execute(s.toString()); } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub } }); /** A method to download json data from url */ private String downloadUrl(String strUrl) throws IOException{ String data = ""; InputStream iStream = null; HttpURLConnection urlConnection = null; try{ URL url = new URL(strUrl); // Creating an http connection to communicate with url urlConnection = (HttpURLConnection) url.openConnection(); // Connecting to url urlConnection.connect(); // Reading data from url iStream = urlConnection.getInputStream(); BufferedReader br = new BufferedReader(new InputStreamReader(iStream)); StringBuffer sb = new StringBuffer(); String line = ""; while( ( line = br.readLine()) != null){ sb.append(line); } data = sb.toString(); br.close(); }catch(Exception e){ Log.d("Exception while downloading url", e.toString()); }finally{ iStream.close(); urlConnection.disconnect(); } return data; } // Fetches all places from GooglePlaces AutoComplete Web Service private class PlacesTask extends AsyncTask<String, Void, String>{ @Override protected String doInBackground(String... place) { // For storing data from web service String data = ""; // Obtain browser key from https://code.google.com/apis/console String key = "key=AIzaSyC3qD9x9SbFGgK69xGtmyieAKaS0kMcpLE"; String input=""; try { input = "input=" + URLEncoder.encode(place[0], "utf-8"); input = input.replaceAll(" ", "%20"); } catch (UnsupportedEncodingException e1) { e1.printStackTrace(); } // place type to be searched String types = "types=geocode"; // Sensor enabled String sensor = "sensor=false"; // Building the parameters to the web service String parameters = input+"&"+types+"&"+sensor+"&"+key; // Output format String output = "json"; // Building the url to the web service String url = "https://maps.googleapis.com/maps/api/place/autocomplete/"+output+"?"+ parameters; try{ // Fetching the data from web service in background data = downloadUrl(url); }catch(Exception e){ Log.d("Background Task",e.toString()); } return data; } @Override protected void onPostExecute(String result) { super.onPostExecute(result); // Creating ParserTask parserTask = new ParserTask(); // Starting Parsing the JSON string returned by Web Service parserTask.execute(result); } } /** A class to parse the Google Places in JSON format */ private class ParserTask extends AsyncTask<String, Integer, List<HashMap<String,String>>>{ JSONObject jObject; @Override protected List<HashMap<String, String>> doInBackground(String... jsonData) { List<HashMap<String, String>> places = null; PlaceJSONParser placeJsonParser = new PlaceJSONParser(); try{ jObject = new JSONObject(jsonData[0]); // Getting the parsed data as a List construct places = placeJsonParser.parse(jObject); }catch(Exception e){ Log.d("Exception",e.toString()); } return places; } @Override protected void onPostExecute(List<HashMap<String, String>> result) { String[] from = new String[] { "description"}; int[] to = new int[] { android.R.id.text1 }; // Creating a SimpleAdapter for the AutoCompleteTextView SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), result, android.R.layout.simple_list_item_1, from, to); Toast.makeText(getApplicationContext(), placesTask+"", Toast.LENGTH_LONG).show(); // Setting the adapter atvPlaces.setAdapter(adapter); } }
Here is placejson code -
public class PlaceJSONParser {
/**
* Receives a JSONObject and returns a list
*/
public List<HashMap<String, String>> parse(JSONObject jObject) {
JSONArray jPlaces = null;
try {
/** Retrieves all the elements in the 'places' array */
jPlaces = jObject.getJSONArray("predictions");
} catch (JSONException e) {
e.printStackTrace();
}
/** Invoking getPlaces with the array of json object
* where each json object represent a place
*/
return getPlaces(jPlaces);
}
private List<HashMap<String, String>> getPlaces(JSONArray jPlaces) {
int placesCount = jPlaces.length();
List<HashMap<String, String>> placesList = new ArrayList<HashMap<String, String>>();
HashMap<String, String> place = null;
/** Taking each place, parses and adds to list object */
for (int i = 0; i < placesCount; i++) {
try {
/** Call getPlace with place JSON object to parse the place */
place = getPlace((JSONObject) jPlaces.get(i));
placesList.add(place);
} catch (JSONException e) {
e.printStackTrace();
}
}
return placesList;
}
/**
* Parsing the Place JSON object
*/
private HashMap<String, String> getPlace(JSONObject jPlace) {
HashMap<String, String> place = new HashMap<String, String>();
String id = "";
String reference = "";
String description = "";
try {
description = jPlace.getString("description");
id = jPlace.getString("id");
reference = jPlace.getString("reference");
place.put("description", description);
place.put("_id", id);
place.put("reference", reference);
} catch (JSONException e) {
e.printStackTrace();
}
return place;
}
}
Help is appreciated.
