How to highlight all instances of variables that are clicked on?

Question

First image is my Netbeans IDE. As you can see whenever I place the text cursor on a variable, that variable is highlighted everywhere else where it appears. I find this feature very helpful and want to enable it on Android Studio (second image).

Answer 1

Have you try this =>

File -> Settings -> Editor -> General -> Highlight on Caret Movement

Then for my personal use, I checked the three options :

-Highlight matched brace -Highlight current scope -Highlight usages os element at caret

enter image description here

Answer 2

Have you tried Identifier under caret setting?

Probably some mismatch with the colors you have set for Foreground and Background

Check my screenshot and let me know how it goes
