title: Explain ClickableViewAccessibility
body: <p>Concerning <a href="https://stackoverflow.com/a/19506010/1587329">the SO swipe code</a>, Android lint gave the warning</p>
  
  <blockquote>
    <p>OnSwipeTouchListener#onTouch should call View#performClick when a click is detected [ClickableViewAccessibility]</p>
  </blockquote>
  
  <p>In the <a href="http://tools.android.com/tips/lint-checks" rel="noreferrer">description of the warning</a>, it says:</p>
  
  <blockquote>
    <p>If a View that overrides onTouchEvent or uses an OnTouchListener does not also
    implement performClick and call it when clicks are detected, the View may not
    handle accessibility actions properly. Logic handling the click actions should
    ideally be placed in View#performClick as some accessibility services invoke
    performClick when a click action should occur.</p>
  </blockquote>
  
  <p>How do you "handle accessibility actions properly"?</p>
