函数onBindViewHolder中的RecyclerView.ViewHolder投放错误

Question

我正在尝试使用recyclerview持有人显示商品清单。 可以使用两种不同的布局显示项目。

但是当我尝试从RecyclerView.ViewHolder转换为我的Viewholder类型时，出现转换错误

（我正在尝试使用recyclerview而不是listview，因为我尝试的方式是，我的列表项上的点击侦听器具有某种缓存。如果我显示列表的前10个元素，则每个元素都有一个onclicklistener滚动，当我单击项目11时，按字节，它正在记录位置1。我已经看到我可能会使用onDetachedFromWindow为项目设置一个空侦听器，这就是我试图对recyclerview进行的操作）

我的recyclerview适配器：

public class WaypointArrayAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private static final int CELL_TYPE_CURRENT_POS = 0;
    private static final int CELL_TYPE_WAYPOINT = 1;
    private List<Cell> cellArrayList;
    private List<Waypoint> waypointList;
    private LayoutInflater layoutInflater;
    private OnItemClickListener mListener;
    Context context;

    public WaypointArrayAdapter(Context context, List<Cell> cellList, List<Waypoint> waypointList) {
        layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        this.context = context;
        this.cellArrayList = cellList;
        this.waypointList = waypointList;
        setListener();
    }

    public void addItem(Cell cell) {
        cellArrayList.add(cell);
    }

    @Override

我的片段：

public class ByTrailList extends Fragment {
// ...
@Override
@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,

        View view = inflater.inflate(R.layout.fragment_by_trail_list, container, false);
        waypointListView = (RecyclerView) view.findViewById(android.R.id.list);
waypointListView = (RecyclerView) view.findViewById(android.R.id.list);

                        displayResult(location);
        }

// ...

private void displayResult(Location aLocation) {

waypointListView.setLayoutManager(new LinearLayoutManager(getContext()));
            waypointListView.setItemAnimator(new DefaultItemAnimator());
            waypointListView.setAdapter(waypointArrayAdapter);
