ImageLoader加载图片时加入淡入效果

ImageLoader.getInstance().displayImage(imagesPath, imageView, initRoundedOptions(rounded), new SimpleImageLoadingListener() {
    final List<String> displayedImages = Collections.synchronizedList(new LinkedList<String>());

    @Override
    public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
        super.onLoadingComplete(imageUri, view, loadedImage);
        if (loadedImage != null) {
            ImageView imageView = (ImageView) view;
            // 是否第一次显示
            boolean firstDisplay = !displayedImages.contains(imageUri);
            if (firstDisplay) {
                // 图片淡入效果
                FadeInBitmapDisplayer.animate(imageView, 500);
                displayedImages.add(imageUri);
            }
        }
    }
});
