I likes to change the subtitle of the action bar.
There’s any implementation?
You can do something like this in ActionBar loaded event,
const nativeView = (<ActionBar>args.object).nativeViewProtected; nativeView.setSubtitle("Your Subtitle");
How to change text color and size?
If you just want to change color you can do something like this,
But if you want to change text size etc, I think you will have to add a Custom View / do it through Android themes.
