title: ImageView is not visible
body: <p>I have two <code>ImageView</code> items in <code>FrameLayout</code>: <em>imageView1</em> and <em>imageView2</em>. <em>imageView1</em> is visible and <em>imageView2</em> is positioned out of screen when activity starts. Then I rotate <code>FrameLayout</code> on some user event using <code>RotateAnimation</code> so <em>imageView2</em> should become visible and <em>imageView1</em> should go out of screen. But <em>imageView2</em> still remains invisible. Does anyone know what's the reason?</p>
  
  <p>The code is too large and complicated to show here. But as I have figured out the main problem in translating and rotating images using <em>setImageMatrix</em> function and special behavior of <code>FrameLayout</code> or <code>ImageView</code>, which crop image if it is out of their bounds.</p>
