Question

我正在使用地理编码来获取城市名称字符串数组的LatLng。问题是，首先，所有城市的名称都很好，但是几个小时后，它并没有首先获得一个城市，然后又获得了两个……现在我被四个城市所识别。我正在将城市名称更改为原始坐标旁边的一个小城市，但是问题仍然存在，而且还在不断增加。我留给我我的MapsActivity和我的地理编码：

（我已经不得不由Badalona改变巴塞罗那，由Azucaica改变托莱多，现在我遇到了塞维利亚和莱昂的麻烦） MapsActivity：

package dam.javazquez.tuvotocuenta.util;

    @Override

        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));

        for (String provincia : provincias) {
            try {
                String[] parts = Geocode.getLatLong(this, provincia).split(",");
                String lat = parts[0];

                        mMap.addMarker(new MarkerOptions().position(loc).icon(BitmapDescriptorFactory.fromResource(R.drawable.podemos)).title("Barcelona"));

                } else {
                    if (provincia.equals("Azucaica")) {
                        mMap.addMarker(new MarkerOptions().position(loc).icon(BitmapDescriptorFactory.fromResource(R.drawable.pp)).title("Toledo"));
                    } else {
                        mMap.addMarker(new MarkerOptions().position(loc).icon(BitmapDescriptorFactory.fromResource(R.drawable.pp)).title(provincia));
                    }
                }
            } catch (IOException e) {
                e.printStackTrace();
            }

        }
        mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
        mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 5));
    }
}

地理编码：

public class Geocode {

    public static String getLatLong(Context ctx,String address) throws IOException {
        Geocoder geocoder = new Geocoder(ctx);
        double latitude = 0;
        double longitude = 0;
        List<Address> addresses;
        addresses = geocoder.getFromLocationName(address, 1);
        if(addresses.size() >= 0) {
            latitude= addresses.get(0).getLatitude();
            longitude= addresses.get(0).getLongitude();
        }

        String result = latitude +","+ longitude;
        return result;
    }
}

非常感谢您！
