包含联系信息的Android联系人列表

Question

是否有人实施了与https://developer.android.com/training/contacts-provider/retrieve-names.html处写的相同的Android联系人列表？我对理解这个源代码有一些问题

public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        ...
        // Gets the ListView from the View list of the parent activity
        mContactsList =
            (ListView) getActivity().findViewById(R.layout.contact_list_view);
        // Gets a CursorAdapter
        mCursorAdapter = new SimpleCursorAdapter(
                getActivity(),
                R.layout.contact_list_item,
                null,
                FROM_COLUMNS, TO_IDS,
                0);
        // Sets the adapter for the ListView
        mContactsList.setAdapter(mCursorAdapter);
    }
