CollapsingToolbarLayout with image, fixed aspect ratio

Question

I have an image inside CollapsingToolbarLayout (exactly the same as in the example https://github.com/chrisbanes/cheesesquare ).

However, I want to fix the aspect ratio of the background as 16: 9.

I tried setting android:layout_height="wrap_content" by updating the LayoutParams code in the code, but it does not work.

Any help?

Solved by putting ImageView inside PercentRelativeLayout.
