Android :: Android - Showing Default Image In Gallery Elements

I believe this is pretty trivial but I can't get it to work. I want to display a default image in gallery elements (ImageViews) while their actual image is being fetched from the net. Right now, nothing is shown for an ImageView which its image has yet to arrive. Once it arrives it is immediately shown. What I tried is right after the instantiation of the ImageView to call its setImageResource function like so:

final ImageView i = new ImageView(mContext);
i.setImageResource(R.drawable.loading);

But it doesn't seem to work. Below is the full getView() function.

public View getView(int position, View convertView, ViewGroup parent) {
final ImageView i = new ImageView(mContext);
i.setImageResource(R.drawable.loading);
// if the drawbale is in the buffer - fetch it from there
Drawable bufferedImage = DataManager.getInstance().getImagesBuffer()[position];
if (bufferedImage != null){ i.setImageDrawable(bufferedImage);
BitmapDrawable drawable = (BitmapDrawable) i.getDrawable();
drawable.setAntiAlias(true);
} // if drawable is not in buffer - fetch it from the net via AsyncImageLoader
else { String imageUrl = DataManager.getInstance().getImageBufferInstance().getImageUrl(position);
Drawable downloadedImage = AsyncImageLoader.getInstance().loadDrawable(imageUrl, new ImageCallback() {
public void imageLoaded(Drawable imageDrawable, String imageUrl) {
if (imageDrawable == null) { imageDrawable = getResources().getDrawable(R.drawable.icon);
} i.setImageDrawable(imageDrawable); BitmapDrawable drawable = (BitmapDrawable) i.getDrawable();
drawable.setAntiAlias(true);
} } ); i.setImageDrawable(downloadedImage);
} i.setLayoutParams(new CoverFlow.LayoutParams(Utils.getInstance().getScreenWidth() / 2, Utils.getInstance().getScreenHeight() / 2));
i.setScaleType(ImageView.ScaleType.CENTER_INSIDE); return i;
