## 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.

![](https://raw.github.com/koush/UrlImageViewHelper/master/helper2.png)

### Download

Download [the latest JAR](http://repository.sonatype.org/service/local/artifact/maven/redirect?r=central-proxy&g=com.koushikdutta.urlimageviewhelper&a=urlimageviewhelper&v=LATEST

) or grab via Maven:

```xml

    com.koushikdutta.urlimageviewhelper

    urlimageviewhelper

    (insert latest version)

```

### 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:

```java

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

```

Want a placeholder image while it is being downloaded?

```java

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

```

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

```java

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

```

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

```java

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

```

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

```java

// 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.

```java

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

```

### FAQ

**Does it work in list adapters when views are reused? (convertView)**

Yes.
