Scaling an image to max available width, keeping aspect ratio and avoiding ImageView extra space

Question

I have this simple layout XML, and a green_square.png file which is 30X30 pixels

Answer 1

There lots of great answers here which actually works. I just what to share the way I do this now with a more modern XML syntax, the constraint view. Trust me constraint view rooks!

of course the tools:context="com.collectsavings.collect.collectpro.LoginAndRegisterPrompt" and android:src="@drawable/green_square" Should all match your app activity context and drawabl resources respectively.
