title: IP address textbox in Android?
body: <p>I'm totally new to Android.</p>
  
  <p>I would like to put in a textbox where user can enter an IP address ... but how do I limit the user to only enter numbers? ... and how do I validate?</p>
  
  <p>Is there a ready-made-ip-address-textbox "out there" I can use?</p>
  
  <p>Thanks!</p>
