Android. Open new Activity through ListView?
<p>I have a problem with my Android Application. In my Application I have a ListView and each item in it contains some text and an image. I want each of the items to open up a different layout. These layouts will just contain some simple text. But I can't seem to find out how to get my items (in the ListView) to open different layouts. Please help!</p>
