Your layout file isn't valid. You also have many expandable layouts and it's unclear which of those are being expanded/collapsed during the animations.

From watching your video it doesn't seem that expandablelayout is to blame for the "flicking". It's either something in your code on in the complexity of your layout file. Please be also aware that ConstraintLayouts are still sometimes buggy so your problem might be related to that.

In any case I'm closing this report since the information here isn't enough to analyse the problem. Please try to reduce your code to as few lines as possible while still reproducing the problem. For more general Android help please try StackOverflow.
