title: Overlap problem with Android ListView selector
body: <p>I am trying to style my ListView with two 9-patch background images (16px * 9px), one dark image for default state and another green image for selected and pressed state. </p>
  
  <p>It works except for just one problem that when I select or press one list item, it seems that the selected item overlap the next one a little bit as I can see some pixels of the green background image is on the top of next item.</p>
  
  <p>How to fix that?</p>
