title: android: how to animate-translate single layer of a LayerDrawable
body: <p>I've looked through the android animation classes but I'm not sure that I'm seeing what I'm looking for. I was wondering if it is possible to add a translate animation (changing the X coordinates) to a single layer of a LayerDrawable? I found the TranslateAnimation class but it seems like that only works with the entire ImageView, and I just want to animate one single layer of my LayerDrawable. Any advice? Thanks in advance.</p>
