title: How to set spacing between font when using drawText
body: <p>I am currently writing a custom TextView to draw text. </p>
  
  <p>Here is the code:</p>
  
  <pre><code>canvas.drawText(text, 0, 0, p);
  </code></pre>
  
  <p>But i can't find any api in <code>Canvas</code> or <code>Paint</code> the define a spacing between font. So how can i set different font spacing for different lines of text.</p>
