如何在RecyclerView的项中使用自定义视图？

我正在尝试在RecyclerView的每个项目中使用ProgressWheel。

如果没有ProgressWheel，它可以正常工作，但是当我在RecyclerView项目中使用这个ProgressWheel时，就会出现异常。

每次添加ProgressWheel后，都会给我以下异常：

适配器方法：
@Override
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType)
    {
        // TODO Auto-generated method stub
        final View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.wallpaper_grid_item, viewGroup, false);

        return new ViewHolder(view);
    }
@Override
public void onBindViewHolder(final ViewHolder viewHolder, final int position)
    {
    }
请展示您的活动/片段和用于RecyclerView项的XML文件。 附上源代码将更好。 - krossovochkin
@ScionofIkshvaku，没有进度轮，它能正常工作吗？ - Smashing
你尝试过在不使用RecyclerView的情况下使用这个Wheel吗？ - krossovochkin
@krossovochkin 是的，我已经在 ListView 中使用过它，效果很好。现在，我想将 ListView 更改为 RecyclerView。 - Amrut Bidri
你确定路径正确吗 com.todddavies.components.progressbar.ProgressWheel？ - vovahost
