recycler-adapter

I want the items in a RecyclerView to have touch feedback or ripples when pressed, but they seem to not be working, and I think it's because of the checkbox.

I am working on grid layout using recyclerview in android. The grid occupies a portion of the screen and has a shadow. To get the desired shadow effect I am using an elevation value of 12 dp. But it does not seem to work as I cannot see any elevation (shadow) of the grid. Why is this happening? Does recyclerview not support elevation? <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:id="@+id/activity_grid_layout" android:background="
