The id problem would be that you try to define list2 as being an id
provided by android itself (@android:id) but it doesn't exist. It's
not something you just make up.
What I did to make your example work was to change list2 to be
android:id="@+id/list2"
Then for testing, here's how I set the adapters...
String[] mStrings = new String[] { "a", "b", "c" };
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, mStrings));
String[] mStrings2 = new String[] { "d", "e", "f" };
ListView secondList = (ListView) findViewById(R.id.list2);
secondList.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
mStrings2));
Note the first setListAdapter is set up to interact with the first
ListView in my ListActivity.
