android - クラス it.gmariotti.cardslib.library.view.CardListView の拡張エラー

Question

この例のcardslibの例に従おうとしていますが、何が間違っているのか分からない例外が発生しています。

これが私のコードです：

public class FragmentA extends Fragment{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {

        final View view = inflater.inflate(R.layout.cards_teste, container, true);
//      CardView cardView = (CardView) inflater.inflate(R.layout.cards_teste, container, false);
        ArrayList<Card> cards = new ArrayList<Card>();

        //Create a Card
        Card card = new Card(getActivity());

        //Create a CardHeader
        CardHeader header = new CardHeader(getActivity());

        //Add Header to card
        card.addCardHeader(header);
        cards.add(card);

        CardArrayAdapter mCardArrayAdapter = new CardArrayAdapter(getActivity(), cards);

        CardListView listView = (CardListView) view.findViewById(R.id.myList_teste);

        if (listView!=null)
        {
            listView.setAdapter(mCardArrayAdapter);
        }
//      return cardView;
        return view;
    }
}

そして、ここに私のXMLファイルがあります:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <it.gmariotti.cardslib.library.view.CardListView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/myList_teste"/>

</LinearLayout>

スタックトレースは次のとおりです。

誰かが例外が発生する理由とその修正方法を説明できますか?

ありがとう
