推荐答案

您可以定义是否图像是使用光盘的高速缓存上盘缓存：

You can define whether image was cached on disc using disc cache:

File cachedImage = imageLoader.getDiscCache().get(imageUrl);
if (cachedImage.exists()) {
    /// image is cached
}

您可以检查每个图像的URL，定义哪些图像缓存并适当配置ViewPager。

You can check every image URL, define which images are cached and configure ViewPager appropriately.
