I need an example to understand how I can go through a jsonArray. This is the example I'm using
/** Receives a JSONObject and returns a list */
public List<HashMap<String,String>> parse(JSONObject jObject){
JSONArray jPlaces = null;
JSONArray jPlacesAll = 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);
}
My class PlaceJSONParser {} takes all json elements and puts them in an array, but I need to check the terms [] of each to filter the city and then put it in the array. I could not access the terms [] can you give me a force ??
The complete class:
public class PlaceJSONParser {
/** Receives a JSONObject and returns a list */
public List<HashMap<String,String>> parse(JSONObject jObject){
JSONArray jPlaces = null;
JSONArray jPlacesAll = 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;
HashMap<String, String> terms = null;
List<HashMap<String, String>> termsList = new ArrayList<HashMap<String,String>>();
/** 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="";
String terms= null;
try {
description = jPlace.getString("description");
id = jPlace.getString("id");
reference = jPlace.getString("reference");
/**
* Formata o endereço para o autocomplete
* */
String[] parts = description.split("-");
String part1 =parts[0]; // endereço , bairro
description = part1;
/** Acrescenta os endereços */
place.put("description", description);
place.put("_id",id);
place.put("reference",reference);
} catch (JSONException e) {
e.printStackTrace();
}
return place;
}
}
