title: Image scaling for tablets
body: <p>I have an image I want to display in ImageView in my layout. As I don't want a distorted Image, I use <code>android:scaleType = "center"</code>.</p>
  
  <p>It looks good on medium and small devices, on large devices (7" and 10"), it is to small and you can see the borders. How can I prevent this?</p>
