android recyclerview 上下滑动导致点击事件和数据错乱问题解决

今天遇到一个奇怪的Bug  上下滑动Item时候 再往上滑 拨打电话 与刚开始不一致，网上很多人说setTag种种，但并没有什么卵用，很鄙视那些复制粘贴的

两种解决方案

getItemViewType(int position){return position} // 这样多种布局应该不方便

在onBidViewHoudle中，添加点击事件的position 不要中onBidViewHoudler的position

用 houdler.getLayoutPosition();

解释

 

/**
 * 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删查改的话，onBidViewHoudler 的 pos不太准确，使用这个方法获取最新位置
