I think this is because we still set backgroundTint in our default MaterialButton style:

https://github.com/material-components/material-components-android/blob/master/lib/java/com/google/android/material/button/res/values/styles.xml#L45

So if you are using a custom android:background, you have to make sure to null out backgroundTint (either app:backgroundTint="@null" or app:backgroundTint="@empty"), so that your custom background doesn’t get tinted.

Or, if all you care about is the color of the button, then you can just use app:backgroundTint instead of android:background, but be sure to set it to a color selector like ours to handle disabled state:

I am using latest version com.google.android.material:material:1.2.0-alpha05. This problem still exists. I can’t override button color using background attribute in XML
