UrlImageViewHelper

UrlImageViewHelper will fill an ImageView with an image that is found at a URL.

Sample Project

The sample will do a Google Image Search and load/show the results asynchronously.

Download

Download the latest JAR or grab via Maven:

<dependency>
    <groupId>com.koushikdutta.urlimageviewhelper</groupId>
    <artifactId>urlimageviewhelper</artifactId>
    <version>(insert latest version)</version>
</dependency>

Usage

UrlImageViewHelper will automatically download and manage all the web images and ImageViews. Duplicate urls will not be loaded into memory twice. Bitmap memory is managed by using a weak reference hash table, so as soon as the image is no longer used by you, it will be garbage collected automatically.

Usage is simple:

UrlImageViewHelper.setUrlDrawable(imageView, "http://example.com/image.png");

Want a placeholder image while it is being downloaded?

UrlImageViewHelper.setUrlDrawable(imageView, "http://example.com/image.png", R.drawable.placeholder);

Don't want to use a placeholder resource, but a drawable instead?

UrlImageViewHelper.setUrlDrawable(imageView, "http://example.com/image.png", drawable);

What if you want to preload images for snazzy fast loading?

UrlImageViewHelper.loadUrlDrawable(context, "http://example.com/image.png");

What if you only want to cache the images for a minute?

// Note that the 3rd argument "null" is an optional interstitial
// placeholder image.
UrlImageViewHelper.setUrlDrawable(imageView, "http://example.com/image.png", null, 60000);

UrlImageViewHelper is pretty smart. It can even load the photo for an Android contact if given a Contact Content Provider URI.

UrlImageViewHelper.setUrlDrawable(imageView, "content://com.android.contacts/contacts/1115", R.drawable.dummy_contact_photo);

FAQ
