Android Question Relative view position

Hello

I have 4 image views from the designer and I need to know how can I get the relative position of those views (Top and Left).

MyImage.Top and MyImage.Left only give me the absolute position.

I founded this: https://www.b4x.com/android/forum/threads/get-relative-view-position.39389/#post-334085

but have a runtime error (after press yes to continue works)



Thanks in advance for any help!
