“Avoid passing null as the view root” warning when inflating view for use by AlertDialog

Question

I get the lint warning, Avoid passing null as the view root when inflating views with null as parent, like:

LayoutInfl         


        

Answer 1

Casting null as ViewGroup resolved the warning:

View dialogView = li.inflate(R.layout.input_layout,(ViewGroup)null);

where li is the LayoutInflater's object.
