Get the displayed size of an image inside an ImageView

The code is simple:

<ImageView android:layout_width="fill_parent"
           android:layout_height="fill_parent"
           android:src="@drawable/cat"/>

Notice the ImageView used fill_parent for width and height.

The image cat is a small image and it will be zoomed in to fit the ImageView, and keep the width/height ratio at the same time.

My question is how to get the displayed size of the image? I tried:

imageView.getDrawable().getIntrinsicHeight()

But which it the original height of the image cat.

I tried:

imageView.getDrawable().getBounds()

But which returns Rect(0,0,0,0).
