title: Android - ImageView bottomCrop instead of centerCrop
body: <p>I'm trying to position an ImageView so that the bottom of the image is always pinned to the bottom of the view, no matter how small the height of the ImageView is. However, none of the scale types seem to fit what I am trying to do. CenterCrop is close, but I don't want the image to be centered. Similar to how CSS would handle absolute positioning.</p>
  
  <p>The reason is, I need to animate the height of the ImageView, but make it seem as though it is "revealing" the upper portion of the image. I assume figuring out this method of cropping the image and animating the ImageView height is the easiest way to do this, but if someone knows of a better way I'd love being pointed in the right direction. </p>
  
  <p>Any help appreciated.</p>
