Loading Images In Gridview Using Universal Image Loader

I'm using the Universal Image Loader 1.8.6 library for loading dinamically images taken from web. The ImageLoaderConfiguration configuration is the following: ImageLoaderConfigurat

Solution 1:

I have solved the problem

I was just declaring option, but I wans't using it, so I have modified the line:

imageLoader.displayImage(basePath+immagine, iv);

into:

imageLoader.displayImage(basePath+immagine, iv, options);

and I have added in the options the method:

.cacheOnDisc(true)

Solution 2:

Caching is not enabled by default in UIL, so if you want use the cache you should use

// Create default options which will be used for every //  displayImage(...) call if no options will be passed to this methodDisplayImageOptionsdefaultOptions=newDisplayImageOptions.Builder()
    ...
    .cacheInMemory()
    .cacheOnDisc()
    ...
    .build();
ImageLoaderConfigurationconfig=newImageLoaderConfiguration.Builder(getApplicationContext())
    ...
    .defaultDisplayImageOptions(defaultOptions)
    ...
    .build();
ImageLoader.getInstance().init(config); // Do it on Application start

And while loading image use:

// Then later, when you want to display image
ImageLoader.getInstance().displayImage(imageUrl, imageView); // Default options will be used

Another way is

DisplayImageOptionsoptions=newDisplayImageOptions.Builder()
    ...
    .cacheInMemory()
    .cacheOnDisc()
    ...
    .build();
ImageLoader.getInstance().displayImage(imageUrl, imageView, options);
