Universal Image Loader: Fading between default background and the image to be loaded

I am using the library Universal Image Loader and I have configured it using the following:



DisplayImageOptions displayImageOptions = new DisplayImageOptions.Builder().resetViewBeforeLoading(true).cacheInMemory(true).cacheOnDisk(false).considerExifParams(false).displayer(new FadeInBitmapDisplayer(300)).delayBeforeLoading(300).handler(new Handler()).build();


On each RecyclerView item/row there is a default background image that gets replaced with a local image. I want the the user to scroll over the RecyclerView and see that default icon as it fades into the local image.



Using the above configuration line, the app fades the image into the placeholder within the row ignoring the default background icon completely. Also, it fades all background images even when they are loaded into the memory.



I have even used .showImageOnLoading() and it did not even show the image. I have increased the fading time and loading time (delayBeforeLoading()) without luck.



The behavior I want is to allow the user to scroll a RecylerView and see the default background icons of the placeholder as they fade into the local image I am loading into that placeholder.



Can this be accomplished using Universal Image Loader? Thanks.



Edit: I have found and used this example:



imageLoader.displayImage(imageUrl, imageView, options, new SimpleImageLoadingListener() 
@Override
public void onLoadingComplete()
Animation anim = AnimationUtils.loadAnimation(MyActivity.this, R.anim.fade_in);
imageView.setAnimation(anim);
anim.start();

);


It has the same issues as the first solution. I have searched for a way to bypass the onLoadingComplete when the image is in memory to skip animation on that special circumstance without luck, too.
