Spinner dropdown list is jumping while scrolling

Question

Why is my spinner jumping while scrolling? I\'m simply doing following:

ArrayAdapter adapter = new ArrayAdapter(v.getContext(), l         


        

Answer 1

I was faced with this.

Problem is anroidx update libs

UPDATE: as Bill Bunting comment "alpha04" is ok now

Resolve by revert version appcompat from "alpha02/alpha03" up to "alpha04"

implementation 'androidx.appcompat:appcompat:1.1.0-alpha04'

or better

implementation 'androidx.appcompat:appcompat:1.0.2' -> for more stable

Answer 2

This is a very annoying, but known bug fixed in 1.1.0-alpha04 of appcompat, as per the release notes Fixed AppCompatSpinnerscrolling in dropdown mode
