As mentioned in the comment

mRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {

  @Override
  public boolean onInterceptTouchEvent(RecyclerView recyclerView, MotionEvent motionEvent) {
    if (motionEvent.getAction() != MotionEvent.ACTION_UP) {
        return false;
    }
    View child = recyclerView.findChildViewUnder(motionEvent.getX(), motionEvent.getY());
    if (child != null) {
      // tapped on child
      return false;
    } else {
      // Tap occured outside all child-views.
      // do something
      return true;
    }
  }

  @Override
  public void onTouchEvent(RecyclerView recyclerView, MotionEvent motionEvent) {
  }
});
