how to see pictures of memory
<p>I'm creating a "hiding picture" application which copies selected picture(s) from the gallery to application memory. It works perfectly and copies the image successfully form gallery to application memory location <code>/data/data/com.isummation.customgallery/files/</code>, and displays saved picture(s) in a <code>ListView</code>. However, I want to show images in a folder view, like this image:</p>

<p><img src="http://i.stack.imgur.com/dzkNv.jpg" alt="enter image description here"></p>

<p>What can I do to achieve this effect?</p>
