AppCompat Toolbar: Change Overflow Icon Color in ActionMode

Question

With the AppCompat Toolbar, I want to be able to change the color of the overflow menu icon on ActionMode change.

For example, the overflow icon will be white in normal

Answer 1

None of the answers here helped me change the overflow icon color of ActionMode independently from the overflow icon color of the normal Toolbar (without resorting to case-by-case styling in code). After some trial and error, I thought that we might override theme attribute of ActionMode independently from Toolbar, and it worked!

In the base theme, we specify the style of action mode like usual:

In our custom ActionModeStyle we do whatever styling we want, and also specify a theme attribute:

textColorSecondary will also change the back button color, but we can easily override that one using actionModeCloseButtonStyle.
