title: Expand clickable area of an ImageView by using padding?
body: <p>I have an ImageView, and I want it to be clickable. The image itself is only 32x32 pixels, but I want the clickable region to be larger so it's easier to hit. I was hoping I could set the layout margin values to increase the size of the imageview's clickable area:</p>
  
  <pre><code>&lt;ImageView
     layout_width="32dip"
     layout_height="32dip"
     layout_margin="20dip" /&gt;
  </code></pre>
  
  <p>That doesn't work, what I could do is just recreate the image resource to have a larger transparent region around it. That's a bit annoying because it's hard to tweak if I ever need to change the clickable region. It's not just a single png either, it's a statelistdrawable so I have to resize 3 different pngs if I ever need to tweak the clickable area.</p>
  
  <p>Anything else I can do?</p>
  
  <p>Thanks</p>
