Zodiac Sign Imageのようなカスタムデータを表示したいリストビューがあります。ゾディアック タイトル。Zodiac コンテンツといくつかのボタン。問題は、データが表示されないことです。すべての行をデバッグし、アイテムが適切に配列リストに追加され、次にアダプターに追加されますが、リストビューは画面に空で表示されます。

ZodicAdapter クラスの getCount() では、0 として返されます。

それを次のようにします

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return items.size();
}
