<p>This sample demonstrates the use of XML adapters.</p>
|
|
|
|
<p>An XML Adapter is an XML file which defines the bindings between the data
|
|
retrieved from a
|
|
<a href="../../../reference/android/content/ContentProvider.html"><code>ContentProvider</code></a>
|
|
and the different views of a layout. They are provided by the
|
|
<a href="../../../reference/android/widget/Adapters.html"><code>Adapters</code></a>
|
|
class.</p>
|
|
|
|
Three list activities are provided which illustrate this:
|
|
<ul>
|
|
<li><a href="src/com/example/android/xmladapters/ContactsListActivity.html"><strong>
|
|
ContactsListActivity</strong></a> uses the device's Contacts provider as its input source.
|
|
Contacts with a phone number are displayed, their photo being retrieved by a dedicated
|
|
<a href="src/com/example/android/xmladapters/ContactPhotoBinder.html"><code>ContactPhotoBinder
|
|
</code></a>.</li>
|
|
|
|
<li><a href="src/com/example/android/xmladapters/PhotosListActivity.html"><strong>
|
|
PhotosListActivity</strong></a> retrieves an RSS photo feed and displays the images and their
|
|
titles. The images are downloaded from the URL found in the feed using the
|
|
<a href="src/com/example/android/xmladapters/ImageDownloader.html"><code>ImageDownloader</code>
|
|
</a> helper class.</li>
|
|
|
|
<li><a href="src/com/example/android/xmladapters/RssReaderActivity.html"><strong>
|
|
RssReaderActivity</strong></a> also displays items extracted from an RSS feed. An additional
|
|
<a href="src/com/example/android/xmladapters/UrlIntentListener.html"><code>UrlIntentListener
|
|
</code></a> is used to open a browser when one of the news item is tapped.</li>
|
|
</ul>
