title: RecyclerView item not showing ripples/touch feedback when the item has a checkbox
body: <p>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.</p>
  
  <p>The ripple is only shown when long pressing, but a simple press won't show it.</p>
  
  <p>May someone help me to fix it? Thanks in advance.</p>
  
  <p>PD: I was using a ListView, and the item layout parent was a LinearLayout. The ripples were working fine. After moving to RecyclerView, the items ripples don't work. I tried with the LinearLayout again, but still not working.</p>
  
  <p>Here's the layout file</p>
