如何禁用涟漪效应？

Question

I have a layout ConstraintLayout which has multiple children, and one child is having the ripple effect

(android:foreground="attr/selectableItemBackground")

and my parent ConstraintLayout also have the same ripple effect. My question is how to disable the child item ripple effect if the parent is already having the ripple, or any conditional way we can use to disable ripple.

when I click on parent item it shows both ripple parent as well as children.

Answer 1

You can use custom style with a transparent color:

<style name="noRipple" parent="Theme.MaterialComponents">
    <item name="rippleColor">@android:color/transparent</item>
</style>

and set in your view:

style="@style/noRipple"

Hope it helps!
