LayoutInflater expects android.content.Context argument type when inflating view

Question

I get rare errors from users when inflating view inside ListView's Adapter. LayoutInflater is retrieved like this:

inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

And layout is inflated here:

convertView = inflater.inflate(R.layout.bla_bla, null);

Stacktrace points to IllegalArgumentException caused by bad context that LayoutInflater uses in method createView()

How can I influence which context LayoutInflater uses? Does this depend on wheather I called getSystemService() method with application Context, or with activity's context?

In my current code, activity is extended from SherlockFragmentActivity ActionBarSherlock's class.

Any help is appreciated, here's the whole stacktrace:

How can I influence which context LayoutInflater uses?

Start by not using getSystemService(). Call getLayoutInflater() on the Activity.

Does this depend on wheather I called getSystemService() method with application Context, or with activity's context?

Yes.

In my current code, activity is extended from SherlockFragmentActivity ActionBarSherlock's class.

All the more reason why you should use getLayoutInflater(), so that you get the correct results.
