Upload image from a url to an Infowindowadapter

Question

I am trying to show an image from a URL on an "Infowindowadapter", but it is never shown. I’m using the Volley library to upload images.

Someone has an idea how to solve this problem?

//no fragment mapa
 map.setInfoWindowAdapter(adapter);

//o adapter
public class InfoViewDetailAdvertiser implements InfoWindowAdapter {

private final View myContentsView;

private ArrayList<Advertiser> advertisers;
private ImageLoader mImageLoader;
private RequestQueue queue;

private NetworkImageView localImage;
private TextView localName;
private TextView localAddressStreetNumber;
private TextView localAddressDistrict;
private TextView localAddressCityState;
private TextView localPhoneNumber;

public InfoViewDetailAdvertiser(Activity activity, ArrayList<Advertiser> advertisers) {
    this.advertisers = advertisers;
    myContentsView = activity.getLayoutInflater().inflate(R.layout.adapter_local, null);

    queue = RequestSingleton.getInstance(
            activity.getApplicationContext()).getRequestQueue();

    mImageLoader = new ImageLoader(this.queue, new LruBitmapCache(
            LruBitmapCache.getCacheSize(activity.getApplicationContext())));
}

public Advertiser getAdvertiser(String id) {
    for (Advertiser advertiser : advertisers) {
        if (id.equals(String.valueOf(advertiser.getId()))) {
            return advertiser;
        }
    }
    return null;
}

@Override

    mapView();
    Advertiser advertiser = getAdvertiser(marker.getTitle());
    loadData(advertiser);

    return myContentsView;

        } else {

I was able to solve the problem. It was necessary to download the image manually. How did the code turn out:

private void loadImage(Marker marker) {
    if (((BitmapDrawable) localImage
            .getDrawable()) == null) {
        new DownloadImage(localImage, marker).execute(urlImage);
    }
    private class DownloadImage extends AsyncTask<String, Void, Bitmap> {

    private ImageView icone;
    private Marker marker;

    public DownloadImage(ImageView imageView, Marker marker) {
        icone = imageView;
        this.marker = marker;
    }

    @Override
    protected Bitmap doInBackground(String... URL) {

        String imageURL = URL[0];
        Bitmap bitmap = null;
        try {
            // Download Image from URL
            InputStream input = new java.net.URL(imageURL).openStream();
            bitmap = BitmapFactory.decodeStream(input);

        } catch (Exception e) {
            e.printStackTrace();
        }
        return bitmap;
    }

    @Override
    protected void onPostExecute(Bitmap result) {
        if (result != null) {
            icone.setImageBitmap(result);
        } else {
            icone.setBackgroundResource(R.drawable.ic_launcher);
        }
        marker.showInfoWindow();
    }
}
