  请检查下面的代码

  public class PlacesDisplayTask extends AsyncTask<Object, Integer, List<HashMap<String, String>>> {
  
          JSONObject googlePlacesJson;
          GoogleMap googleMap;
  
          @Override
          protected List<HashMap<String, String>> doInBackground(Object... inputObj) {
  
              List<HashMap<String, String>> googlePlacesList = null;
              Places placeJsonParser = new Places();
  
              try {
                  googleMap = (GoogleMap) inputObj[0];
                  googlePlacesJson = new JSONObject((String) inputObj[1]);
                  googlePlacesList = placeJsonParser.parse(googlePlacesJson);
              } catch (Exception e) {
                  Log.d("Exception", e.toString());
              }
              return googlePlacesList;
          }
  
          @Override
          protected void onPostExecute(List<HashMap<String, String>> list) {
              googleMap.clear();
              for (int i = 0; i < list.size(); i++) {
                  MarkerOptions markerOptions = new MarkerOptions();
                  HashMap<String, String> googlePlace = list.get(i);
                  double lat = Double.parseDouble(googlePlace.get("lat"));
                  double lng = Double.parseDouble(googlePlace.get("lng"));
                  String placeName = googlePlace.get("place_name");
                  String vicinity = googlePlace.get("vicinity");
                  LatLng latLng = new LatLng(lat, lng);
                  markerOptions.position(latLng);
                  markerOptions.title(placeName + " : " + vicinity);
                  googleMap.addMarker(markerOptions);
              }
          }
      }
