hasOverlappingRendering() and two ImageViews

Question

I have a custom View, which contains, amongst others, two ImageViews on top of each other. I set hasOverlappingRendering() to return false, and haven't had any issues while setting alpha.

But doesn't it really contain overlapping rendering (the two ImageViews)? Shouldn't this be a (graphical) error of some sort?

Answer 1

A late answer.. But better late than never. The answer is that doesn't contain overlapping rendering. I found this video really useful.

Google engineers are explaining with an example what is happening when you return false from the hasOverlappingRendering().
