使用 Cardlib： "CardView cannot be cast to CardNativeView"

Question

我刚刚在我的代码中实现了cardlib。

我正在使用以下代码来实现TopColoredCard：

ArrayList<Card> cards = initCard();
updateAdapter(cards);    
...
private ArrayList<Card> initCard() {
    //Init an array of Cards
    ArrayList<Card> cards = new ArrayList<>();
    for (int i = 0; i < AppData.mTitles.length; i++) {
        TopColoredCard card = new TopColoredCard(getApplicationContext());
        card.setColorResourceId(AppData.mColors[i]);
        card.setTitleOverColor(AppData.mTitles[i]);
        card.setSubTitleOverColor(subTitle(i));
        cards.add(card);
    }
    return cards;
}

并实现：

compile 'com.android.support:cardview-v7:21.0.3'
compile 'com.github.gabrielemariotti.cards:cardslib-core:2.0.1'
compile 'com.github.gabrielemariotti.cards:cardslib-recyclerview:2.0.1'
compile 'com.github.gabrielemariotti.cards:cardslib-cards:2.0.1'

它在Android 5.0及更高范围内效果很好。在较低版本上，我会收到以下错误：

我认为这是LIB的错误，因为它在API LVL上起作用。20但是它在较低版本上不起作用。

也许你们中的任何人都可以帮助我。

//编辑：这是我的layout.xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="@color/background_material_light"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <include
        android:id="@+id/toolbar_actionbar"
        layout="@layout/toolbar_default"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
    <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipeRefreshLayout"

        android:layout_below="@id/toolbar_actionbar">
        <view

            android:layout_height="match_parent"
            class="it.gmariotti.cardslib.library.recyclerview.view.CardRecyclerView"
            android:id="@+id/recycler" />
    </android.support.v4.widget.SwipeRefreshLayout>

</RelativeLayout>

将您的类从XML文件中的CardView更改为cardNativeView。
