错误显示事件描述数据无法转换为列表<EventDescriptionData>

Question

我面对解决这个问题几天我在json中声明数组。在这段代码中，错误显示不兼容的类型:EventDescriptionData不能转换为列表，即setAdapter我不能传递适当的参数。请大家帮帮我。

public class MainActivity extends BaseActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_event_layout);
    }
    @Parcel
    public static class EventDescriptionData {
        /* Data for Pre Event Ticket Crausal Card  */
        @SerializedName("children")
        public List<carouselImage> mPreEventCrausal;      
        }
        @Parcel
        public static class carouselImage {
            @SerializedName("src")
            public String mImgSrc;
        }
}
public class CardPreEventDhamakaView extends LinearLayout {
    private CardPreEventDhamakaView(final Context context, MainActivity .EventDescriptionData eventData) {
        super(context);
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        inflater.inflate(R.layout.cardview_preevent_dhamaka, this, true);
        CardView view = (CardView) findViewById(R.id.cardPreEventParentView);
        Gallery gallery = (Gallery) findViewById(R.id.cardPreEventgallery);
        gallery.setAdapter(new CardPreEventDhamakaViewData(getContext(), eventData));
    }
    public static class CardPreEventDhamakaViewData extends BaseAdapter {
        private Context mContext;
        private List<MainActivity.EventDescriptionData> mCardData;
        public CardPreEventDhamakaViewData(Context context , List<MainActivity.EventDescriptionData> eventData)
        {
            mContext=context;
            mCardData = eventData;
        }
        public int getCount() {
            return mCardData.size();
        }
        @Override
        public Object getItem(int i) {
            return i;
        }
        public long getItemId(int i) { return i; }
        public View getView(int i, View view, ViewGroup viewGroup) {
            ImageView imageView = new ImageView(mContext);
            Picasso.with(mContext).load(mCardData.get(i).mPreEventCrausal.get(i).mImgSrc)
                    .placeholder(R.drawable.placeholder_carousel).into(imageView);
            imageView.setAdjustViewBounds(true);
            imageView.setScaleType(ImageView.ScaleType.FIT_XY);
            imageView.setLayoutParams(new Gallery.LayoutParams(
                    ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
            return imageView;
        }
    }
}

EventDescriptionData public List mPreEventCrausal是carouseImage的集合。要么将此列表作为参数传递给基本适配器，要么创建PreEventDetailsActivity的集合。EventDescriptionData并传递列表。

public CardPreEventDhamakaViewData(Context context , List<PreEventDetailsActivity.EventDescriptionData> eventData) --> no where you are creating a list of EventDescriptionData objects.
