使用 Cardslib：“CardView 无法转换为 CardNativeView”

Question

我刚刚在我的代码中实现了Cardslib。

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;
}

并实施：

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 及更高版本上运行良好。 在较低版本上，我收到以下错误：

我认为这是 lib 的错误，因为它适用于 API lvl。 20 但它不适用于低版本。

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">

</RelativeLayout>

在您的 xml 文件中将您的类从 CardView 更改为 CardNativeView。
