How to change the color of a Material Floating Action Button while being pressed?

Question

How can I change the color of the FAB while the button is being pressed? I don't see a property like onPressed().

Answer 1

You can use the app:rippleColor in your layour or the rippleColor attribute in the FAB style.

Where fab_ripple should be a selector.

Something like:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
      <item android:alpha="..." android:color="?attr/colorOnSecondary" android:state_pressed="true"/>
      <item android:alpha="..." android:color="?attr/colorOnSecondary" android:state_focused="true"/>
      <item android:alpha="..." android:color="?attr/colorOnSecondary" android:state_hovered="true"/>
      <item android:alpha="..." android:color="?attr/colorOnSecondary"/>

</selector>
