如何禁用涟漪效应？
How to disable the ripple effect?
我有一个布局 ConstraintLayout，其中有多个 children，其中一个 child 具有连锁反应
(android:foreground="attr/selectableItemBackground")
和我的parentConstraintLayout也有同样的连锁反应。我的问题是如果 parent 已经有涟漪，或者我们可以使用任何条件方式来禁用涟漪，如何禁用 child 项目涟漪效应。
当我点击 parent 项目时，它同时显示波纹 parent 和 children。

您可以使用透明颜色的自定义样式：
<style name="noRipple" parent="Theme.MaterialComponents">
<item name="rippleColor">@android:color/transparent</item>
</style>
并在您的视图中设置：
