android recyclerview 上下滑動導緻點選事件和資料錯亂問題解決

getItemViewType(int position){return position} // 這樣多種布局應該不友善

在onBidViewHoudle中，添加點選事件的position 不要中onBidViewHoudler的position

用 houdler.getLayoutPosition();

解釋 /**

• Returns the position of the ViewHolder in terms of the latest layout pass.
• This position is mostly used by RecyclerView components to be consistent while
• RecyclerView lazily processes adapter updates.
• For performance and animation reasons, RecyclerView batches all adapter updates until the
• next layout pass. This may cause mismatches between the Adapter position of the item and
• the position it had in the latest layout calculations.
• LayoutManagers should always call this method while doing calculations based on item
• positions. All methods in {@link RecyclerView.LayoutManager}, {@link RecyclerView.State},
• {@link RecyclerView.Recycler} that receive a position expect it to be the layout position
• of the item. 大緻意思就是涉及增删查改的話，onBidViewHoudler 的 pos不太準确，使用這個方法擷取最新位置
