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

ChenXi1995發表於2019-02-28

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
