title: Get the size of a text in TextView
body: <p>I have a problem placing a textView at specified center's x and y coordinates.
  Firstly, I tried to set the text in the textView, and to move the view with the width and the height of the view 
  <a href="https://stackoverflow.com/questions/6653359/how-to-move-a-textview-to-an-x-and-an-y-in-a-relativelayout/6654371#6654371">from this link</a>.</p>
  
  <p>But it doesn't work, and I'd like to try something else.
  I'd like to know if there is a method to get the size which a specified text will take in my textView? 
  I mean, I know the text and the textSize, how can I get the width and the height my textView will take?</p>
  
  <p>Something like the method <code>(NSString)sizeWithFont;</code> for those who know iPhone dev.</p>
