Make ImageView display black portions of image as different color

Question

How can I replace the black color with transparent color (or some other color) in an ImageView?

I load image from web using Picasso:

Picasso.with(getContext()).load("www.abc.com/a.png").into(myImageView);

Currently it looks like this:

The image itself contains the black background, which I want to remove. I tried using myImageView.setColorFilter(Color.BLACK); but it doesn't seem to work.

Andy Developer's answer helped, but I had to manually convert black pixels to pixels of my liking. It is working, although I am not sure if this is the best way.

Picasso.with(getContext()).load(IMAGE_URL).into(new Target() {
    @Override
    public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from)
    {
        Bitmap copy = bitmap.copy(bitmap.getConfig(),true);

        int [] allpixels = new int [copy.getHeight()*copy.getWidth()];
        copy.getPixels(allpixels, 0, copy.getWidth(), 0, 0, copy.getWidth(), copy.getHeight());

        int replacementColor = Color.parseColor("#34495E");
        for(int i = 0; i < allpixels.length; i++) {
            if(allpixels[i] == Color.BLACK)
                allpixels[i] = replacementColor;
        }

        copy.setPixels(allpixels, 0, copy.getWidth(), 0, 0, copy.getWidth(), copy.getHeight());

        myImageView.setImageBitmap(copy);
    }

    @Override
    public void onBitmapFailed(Drawable errorDrawable) { }

    @Override
    public void onPrepareLoad(Drawable placeHolderDrawable) { }
});
