getItemViewType(int position){return position} // 這樣多種佈局應該不方便
在onBidViewHoudle中,新增點選事件的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. 大致意思就是涉及增刪查改的話,onBidViewHoudler 的 pos不太準確,使用這個方法獲取最新位置
