使用Cardslib：「CardView不能轉換爲CardNativeView」

我剛剛在我的代碼中實現了Cardslib。使用Cardslib：「CardView不能轉換爲CardNativeView」

我用下面的代碼來實現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; 
}

並實現了：

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'

它運作良好，在Android 5.0及更高版本。較低版本我得到以下錯誤：

我認爲這是11b的缺陷，因爲它適用於API拉特。 20，但它不適用於較低版本。

也許任何人都可以幫助我。

你還可以在佈局文件中發佈你的CardListView嗎？ – Sharj

@Sharj編輯我的帖子。 – ich5003

更改從CardView你的類CardNativeView在XML文件中。
