Error in getListView().getContext()

my code

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
                            getListView().getContext(),
                            android.R.layout.simple_list_item_checked, usernames);
                    setListAdapter(adapter);

is giving me an error.

getListView().getContext() and setListAdapter both have errors when copying into RecipientsActivity.java

  1. cannot resolve method getListView()

  2. cannot resolve method setListAdapter(adapter);

Hey Andy!

What are you extending in RecipientsActivity.java?

Thanks Andy!

The problem is that the method getListView() is actually from the ListActivity class (See here). Therefore, you must extend ListActivity in order to use it.

Hope it helps and, if you have any questions about this, give me a shout :)
