title: Is there a way to pass parameters to a Runnable?
body: <p>I have a thread that uses a handler to post a runnable instance.  it works nicely but I'm curious as to how I would pass params in to be used in the Runnable instance?  Maybe I'm just not understanding how this feature works.</p>
  
  <p>To pre-empt a "why do you need this" question, I have a threaded animation that has to call back out to the UI thread to tell it what to actually draw.</p>
