[android][demo] Demonstration of using and styling latest material components
The included Styles show-case the different suggested material buttons following a defined accent color. Defining custom selector based colors allows correct looking disabled states.
The primary style (filled & hovering button) comes with a hard-coded grey disabled color (Internally color/mtrl_btn_bg_color_disabled used in a selector).
Note that especially in Dark Mode the default disabled colors are hardly readable.
Previous documentation / solutions on the internet stated that the disabled state was defined via colorButtonNormal. This is no longer true with the Material Components Button!
The button active and disabled color can instead be overwritten using tint. Ensure to provide a selector color for a visual different disabled look.
Using a button with just a colored outline is one of the new material component button styles. Customizing the button by setting the strokeColor is straight-forward.
Accent colored action text links can now also use a Material Button. This way it is very easy to switch between different button styles. As bonus the ripple effect highlight when pressing the text link works out of the box.
When using with an icon the iconTint must be set too.
