Answer 1

I found a good article about LayoutInflater. The author explains how all the versions of the inflate method work and gives examples of ListView and AlertDialog

Update #1.

This answer recently helped me, too. https://stackoverflow.com/a/5027921/1065835

Answer 2

Here ya go, for some reason using View.inflate instead of inflating from a layoutinflater makes the lint error disappear. Thought I'd post this here since this thread is at the top of the Google Search...

view = View.inflate(context,R.layout.custom_layout,null);

Answer 3

Here is a picture for reference:

return inflater.inflate(R.layout.some_layout, container, true); 
// for the last parameter use true, false or simply don't declare

Answer 4

When you really don't have any parent (for example creating view for AlertDialog), you have no other way than passing null. So do this to avoid warning:

final ViewGroup nullParent = null;
convertView = layoutInflater.inflate(R.layout.list_item, nullParent);

Answer 5

Instead of doing

convertView = infalInflater.inflate(R.layout.list_item, null);

do

convertView = infalInflater.inflate(R.layout.list_item, parent, false);

It will inflate it with the given parent, but won't attach it to the parent.

Answer 6

For AlertDialog bellow code can be used

convertView = layoutInflater.inflate(R.layout.list_item, findViewById(android.R.id.content), false);
