I have a RecyclerView with a ConstraintLayout as the root View of each item.
I am setting the ConstraintLayout background as a selector, the selector is defined as:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="?attr/selectableItemBackground" android:state_pressed="true" />
<item android:drawable="@color/colorAccent" android:state_activated="true" />
<item android:drawable="@android:color/transparent" />
</selector>
My goal was to have the ripple effect when an item is pressed, and change the item's background to the accent color when the item is selected.
The problem is, selectableItemBackground works on any View's background, but if I place it on the selector as it is, my app crashes as soon as the ConstraintLayout is inflated.
If I remove the ?attr/selectableItemBackground and substitute it for any color, the selector works just fine.
Here's the simplified crash error on Logcat:
