Why do my line numbers keep disappearing in Android Studio?

Question

I want to display line numbers in my Android Studio editors.

I have turned line numbers ON in preferences

Preferences > Editor > Appearance

However, line numbers do not appear.

If I drop down the View menu and look at the Show Line Numbers option, it is NOT checked.

View > Active Editor > Show Line Numbers

If I check it, line numbers show. However, if I move my cursor to a different character or line, they immediately disappear.

Why is this happening?

Answer 1

as @pgoggijr said already, this is a problem I was having with IDEAVim as well. however, you don't have to turn vim off. Just use the vim commands

:set nu

and

:set nonu

to toggle line numbers on and off, and these stay :)

Answer 2

I'm assuming that you're using the ideaVim emulator.

There seems to be a bug in the ideaVim plugin that has surfaced in recent versions of Android Studio that makes line numbers disappear once the cursor moves

Turn off the emulator (tools > VIM emulator), and it should be fine.
