android - 更改纬度和经度时，地理编码器无法使用更新地址

Question

每次我移动 map 时，它都会进入 onLocationChanged block ，并且还会获取新的纬度和经度，但它不会更新地址，但会显示首次加载的地址。我正在使用以下内容更新地址:

@Override
public void onLocationChanged(Location location) {

    Log.e("change" , "change");

    double latitude = location.getLatitude();
    double longitude = location.getLongitude();

    try {
        Geocoder geo = new Geocoder(this, Locale.getDefault());
        List<Address> addresses = geo.getFromLocation(latitude, longitude, 1);
        if (addresses.isEmpty()) {

            Log.e("TAG", "Waiting for Location");
        }
        else {
            if (addresses.size() > 0) {
                Log.e("TAG", addresses.get(0).getFeatureName() + ", " + addresses.get(0).getLocality() + ", " + addresses.get(0).getAdminArea() + ", " + addresses.get(0).getCountryName());
                //yourtextfieldname.setText(addresses.get(0).getFeatureName() + ", " + addresses.get(0).getLocality() +", " + addresses.get(0).getAdminArea() + ", " + addresses.get(0).getCountryName());
                //Toast.makeText(getApplicationContext(), "Address:- " + addresses.get(0).getFeatureName() + addresses.get(0).getAdminArea() + addresses.get(0).getLocality(), Toast.LENGTH_LONG).show();
            }
        }
    }
    catch (Exception e) {
        e.printStackTrace(); // getFromLocation() may sometimes fail
    }
}

Geocoder 在某些设备上不可用，请使用 Google API Client 代替 Geocoder
