title: What's the difference between ViewFlipper and ViewSwitcher
body: <p>They both inherit <code>ViewAnimator</code>. I know that <code>ViewSwitcher</code> allows only two views, while <code>ViewFlipper</code> allows more. But why did Android create <code>ViewSwitcher</code>, if it is just a <code>ViewFlipper</code> with 2 views? Are there any other differences? On what condition will be using the one superior than the other?</p>
