Animations and Transitions - Challenge Task 1 of 3

You need to animate an image (named imageView) so that it scales up to twice its size when it is tapped. Start by simple calling the animate() method of the image. Ben Jakuben

CodeChallenge.java 
// Use the variable named 'imageView'
 private void animate() {
        imageView.setScaleX(0);
        imageView.setScaleY(0);
        imageView.animate().scaleX(1).scaleY(1).start();  //Animation code
    }

I think this is challenge task 2 of 3, no?

Also, I'm still working on this so I don't know the answer yet, but I don't think ImageViews have the method 

setScaleX()

or 

setScaleY()

since I get the following error when running your code snippet:

JavaTester.java:68: error: cannot find symbol
  imageView.setScaleX(0);
           ^
  symbol:   method setScaleX(int)
  location: variable imageView of type ImageView
JavaTester.java:69: error: cannot find symbol
        imageView.setScaleY(0);
                 ^
  symbol:   method setScaleY(int)
  location: variable imageView of type ImageView
