custom gallery with swipe
<p>What is the best way to present a full screen picture gallery read from a directory.</p>

<p>I was thinking of using an ImageView for full screen bitmap display and then using viewPager for swipeing to the next image. 
Which would mean that I would need to have at least PICTURE,PICTURE+1 and PICTURE-1 always in memory.</p>

<p>is this proper way or is there a better one?</p>
