How can I disable Android Lollipop ripple's alpha value?
You can simply put alpha value for bounded ripple.
<ripple xmlns:android="http://schemas.android.com/apk/res/android" android:color="?android:attr/colorAccent"> <item android:id="@android:id/mask"> <color android:color="#42ffffff" /> </item></ripple>for unbounded ripple You can set opacity from color if you know your accent color
<ripple xmlns:android="http://schemas.android.com/apk/res/android" android:color="@color/accent_26" />colors.xml
<resources> ... <color name="accent">#ff33b5e5</color> <color name="accent_alpha26">#4233b5e5</color></resources>
