“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

You should use AlertDialog.Builder.setView(your_layout_id), so you don't need to inflate it.

Use AlertDialog.findViewById(your_view_id) after creating the dialog.

Use (AlertDialog) dialogInterface to get the dialog inside the OnClickListener and then dialog.findViewById(your_view_id).
