I want to parse the entire JSON file that contains many JSONObjects
"steps". I need to extract all polylines and their points. However, it
returns only the very first value and nothing more. Is anything wrong with
my loop or I just parse the JSON file wrongly? Thx
public void parseDirect(String response) {
PolylineOptions polylineOptions = new PolylineOptions();
List<LatLng> movements = new ArrayList<>();
try{
JSONObject json = new JSONObject(response);
//Retrieve routes from response
JSONObject jsonRoute = json.getJSONArray("routes").getJSONObject(0);
//Retrieve legs from routes
JSONObject legs = jsonRoute.getJSONArray("legs").getJSONObject(0);
//Retrieve steps from legs
JSONArray steps = legs.getJSONArray("steps");
final int numSteps = steps.length();
JSONObject step;
//Retrieve points from steps
for (int i = 0; i < numSteps; i++) {
step = steps.getJSONObject(i);
String pontos =
step.getJSONObject("polyline").getString("points");
movements.addAll(PolyUtil.decode(pontos));
}
// movementsTest.add(new LatLng(52.4634252,-1.8861262));
// movementsTest.add(new LatLng(52.4761324,-1.8608113));
// movementsTest.add(new LatLng(52.4634252,-1.8689613));
polylineOptions.color(Color.RED);
polylineOptions.width(10);
polylineOptions.addAll(movements);
mMap.clear();
mMap.addPolyline(polylineOptions);
Log.i("parser", "parseDirect: " + movements.toString());
}catch(Exception ex){
Log.d("DirectionErr",ex.getMessage());
}
//make use of movements object here
}
