Android : How to put an ImageView relative to a background image in Android Studio

For my GUI i use the RelativeLayout and want to keep it as it is the best for different screeen resolutions.

For example i have this Background, where i want to put an ImageView exactly over the TV-screen (to show some pictures on the TV).

I want this to work in different screen resolutions.

How can i achieve this? Or is this even possible? Examples are welcome :)
