onBindViewHolder 处的 Recyclerview Class

Question

我在 RecyclerView 里面做了 RecyclerView。有ClassCastException在 onBindViewHolder。

错误信息在这里。

    java.lang.ClassCastException: com.work.hany.playinseoul.main.adapter.MainRecyclerViewAdapter$TourViewHolder$TourSectionItemsAdapter$TourItemViewHolder cannot be cast to com.work.hany.playinseoul.main.adapter.MainRecyclerViewAdapter$CategoryViewHolder$CategoryItemViewHolder

    at com.work.hany.playinseoul.main.adapter.MainRecyclerViewAdapter$CategoryViewHolder$CategoryHorizontalAdapter.onBindViewHolder(MainRecyclerViewAdapter.java:216)

    at android.support.v7.widget.RecyclerView$Adapter.onBindViewHolder(RecyclerView.java:6673)

    at android.support.v7.widget.RecyclerView$Adapter.bindViewHolder(RecyclerView.java:6714)

但我无法赶上ClassCastException的TourSectionItemsAdapter onBindViewHolder。因此，我无法在 TourSectionItemsAdapter onBindViewHolder 上检查持有人类型。

只有我在 MainRecyclerViewAdapter onBindViewHolder 上捕获了 ClassCastException。但是 MainRecyclerViewAdapter onBindViewHolder 持有人类型是相同的投 hodler 类。检查屏幕截图。

也许为时已晚，但对于功能读者来说，只需像这样定义 viewPoolprivate val viewPool = RecyclerView.RecycledViewPool()
