title: Live character count for EditText
body: <p>I was wondering what the best way to do a live character count of an edit-text box is in Android. I was looking at <a href="http://developer.android.com/reference/android/view/KeyEvent.html" rel="noreferrer">this</a> but I couldn't seem to make any sense of it. </p>
  
  <p>To describe the problem, I have an EditText and I'm trying to limit the characters to 150. I can do this with an input filter, however I want to show right below the text box the number of characters a user has entered(Almost like stack overflow is doing right now).</p>
  
  <p>If someone could write a small snippet of example code or point me in the right direction I'd appreciate it a lot.</p>
