By default, Buttons give some feedback while the user is touching them before the touch is released. On Android, the button's background color changes and on iOS the text darkens. However, if I set a custom BackgroundColor for a Button there is no longer any visual feedback on Android that the button is being touched. Is there some way to set a color for the button to use while it is being touched similar to the behavior seen with the default settings?
More generally, the Clicked event seems to fire once the touch is released. Is there an event available for the initial touch?
