title: animating a drawline in Android
body: <p>I wanted to animate a line on the view. Ex: A progressive line starting at (0,120) and progresses upto (100,120). I've already tried this with plain canvas.drawLine() but was unable to apply an animation while drawing a line. 
  What I wanted to see is once the view is loaded a set of straight lines(of varying length) being drawn on the view. I don't want them as static lines. I wanted to see these lines when they are being drawn on the canvas.</p>
  
  <p>I've tried couple of other options like, using the shape drawables and applying animations from the anim/xmls. Most of them didn't solve my problem. Extensive googling show the animations which are applied to the views directly. Here I dont want to create multiple image views as I'll end up having 6 lines on the view and i need to animate each of the line with different colors. </p>
  
  <p>In future I should be able to move the lines up and down change there colors and do other kind of animations on each one of the lines. </p>
  
  <p>Remembering the above constraints can you suggest me how to write a custom implementation for the same.</p>
