Вопрос:
В моем recyclerview адаптере у меня есть два типа представления native ad view type и пункт меню, в моем адаптере ниже я получаю следующую ошибку.
java.lang.ClassCastException: java.util.ArrayList не может быть преобразован в модель.VideoListModel в адаптере.MainListAdapter.onBindViewHolder(MainListAdapter.java:95)

я добавил Model , но все равно получаю сообщение об ошибке. Так какую же ошибку я совершил ?
Комментарии:
1. Возможно, вы передали ArrayList, например ArrayList<ArrayList>, в adapter constractor
2. @mostafa3dmax нет, вот как я прошел
ArrayList<Object> arrayListVideos = new ArrayList<>();3. Добавьте свой код действия, в котором вы создаете экземпляр своего адаптера и RecyclerView
4. @mostafa3dmax я обновил свой код.
5. Я думаю, что ваш код действия неверен! Как вы прошли
List<VideoListModel> modelspublic MainListAdapter(Context context, ArrayList<Object> arrayList)?MainListAdapterПодрядчик получаетArrayList<Object>в качестве вторых параметров, поэтому вы не можете передать егоList<VideoListModel>! Я думаю, вы передалиArrayList<Object> arrayListVideosегоMainListAdapterподрядчику. и в вашемonResultметоде вы передалиmodelsэто ArrayList вarrayListVideos:arrayListVideos.add(models);
Ответ №1:
public class MainListSuperClass {
}
Создайте класс MyUnifiedNativeAd :
public class MyUnifiedNativeAd extends MainListSuperClass{
private UnifiedNativeAd mUnifiedNativeAd;
public MyUnifiedNativeAd(UnifiedNativeAd unifiedNativeAd) {
mUnifiedNativeAd = unifiedNativeAd;
}
public UnifiedNativeAd getUnifiedNativeAd() {
return mUnifiedNativeAd;
}
public void setUnifiedNativeAd(UnifiedNativeAd unifiedNativeAd) {
mUnifiedNativeAd = unifiedNativeAd;
}
}
расширить VideoListModel из MainListSuperClass :
public class VideoListModel extends MainListSuperClass{
...
}
Код адаптера :
public class MainListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private static final int MENU_ITEM_VIEW_TYPE = 0;
private static final int UNIFIED_NATIVE_AD_VIEW_TYPE = 1;
private final Context mContext;
private final ArrayList<MainListSuperClass> arrayList;

this.mContext = context;
this.arrayList = arrayList;

1. у меня нет класса
UnifiedNativeAd. И у меня естьVideoListModelфайл add class2. создайте класс, который расширяет
UnifiedNativeAdlikeMyUnifiedNativeAd extends UnifiedNativeAdиMyUnifiedNativeAdMainListSuperClassimplementate, и изменитеMainListSuperClassтип на interface3. можете ли вы опубликовать код, как это должно быть сделано. полный код..
4. Я отредактировал свой код. Сначала проверьте, не является ли UnifiedNativeAd окончательным, и вы можете расширить его
5. У вас его нет, но можете ли вы расширить его?
