How to change toolbar icon colors when switching theme?

Question

Java

The application has dark and light themes. I wanted the colors of the icons to change when switching them.
I have 2 options here so far:
1) separately store black and white versions of icons, have 2 layouts for the menu (one with black icons, the other with white ones)
2) somehow programmatically change their colors

Answer 1

Now I'm sitting on the same thing and I have a third option. I specified android:fillColor="?android:attr/textColor" in the XML of each icon. In a light theme, the text is dark, and in a dark theme, respectively, it is light. The icons will recolor automatically when the theme is changed, I hope. Now I will check.
