Draw a shape, and make it bigger when user touches
<p>I have seen how to draw a shape in Android, but what I want to know is how to rescale the shape when the user touches over the shape.</p>

<p>Imagine a square into a screen corner, so when you touch it, it grows until fitting the whole screen. I'd like to make that with a transition, animated, not instant.</p>

<p>Any idea of how to do that, or any known resource?</p>
