title: ViewPager offscreen page limit
body: <p>Is there a way to bypass the normal behavior of <code>ViewPager</code> and its <em>offscreen page limit</em>?
  My <code>ViewPager</code> contains four <code>fragments</code>, each containing a <code>gridview</code> of images. The problem I have is that on instansiation of the <code>ViewPager</code>, two <code>fragments</code> are created, which results in that about 20 images (about 10 per fragment) is downloaded/fetched from catch simultaneously. Is it possible to disable the offscreen page limit?</p>
  
  <p>My goal is to only download images when a <code>fragment</code> is selected, or only when the user is hovering the image. One way to achieve this is to use the <code>onPageSelected</code> listener and set a flag, which tells the <code>GridViewAdapter</code> if it's allowed to download the image or not.</p>
  
  <p>A second way that I can think of is to set a <code>HoverListener</code> on the <code>ImageView</code>, and only download the image on <code>onHover</code>, but that listener is only available in 4.0 and later.</p>
  
  <p>Is there a better way to achieve this?</p>
