UrlImageViewHelper will fill an ImageView with an image that is found at a URL.
The sample will do a Google Image Search and load/show the results asynchronously.
Download the latest JAR or grab via Maven:
<dependency>
<groupId>com.koushikdutta.urlimageviewhelper</groupId>
<artifactId>urlimageviewhelper</artifactId>
<version>(insert latest version)</version>
</dependency>
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);
Does it work in list adapters when views are reused? (convertView)
Yes.
