title: Android ViewPager padding/margin between page fragments
body: <p>Android Market/Google Music seem to be able to have a gap of some sort between the different fragments that are contained in the <code>ViewPager</code>. </p>
  
  <p>Any idea how this is done? Adding margin/padding to the actual fragment view doesn't work, because the view still needs to occupy the entire width of the screen. The 'gap' is only visible when swiping the ViewPager.</p>
