How to display only cache memory images in ViewPager using Universal Image Loader Android?


I want to display only those images that were loaded into cache memory once we downloaded from url using Universal Image Loader

Example

I have 15 URLS to download image and display inViewPager, but out of them only 5 were downloaded and i closed the app.. Now i don't have any internet connection to get all the other images from web, but app will show only 5 images and remaining pages will be blank..

Is is possible to get the list of only those images from cache Memory??

How can we restrict ViewPager from other blank pages?

I have successfully implemented Universal Image Loader, but got stuck on these issues.

Any idea/suggestion/sample would be appreciated..

Thanks


Solution

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

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

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