【中文标题】Android RecyclerView Adapter notifyItemChanged() 获取 IllegalStateException 已经在池中【英文标题】：Android RecyclerView Adapter notifyItemChanged() getting IllegalStateException Already in the pool 【发布时间】：2018-07-10 12:44:25 【问题描述】：我正在使用 Recyclerview 并通过 notifyItemChanged() 对其进行更新 使用线性布局管理器的recyclerView 当从套接字更新数据时，我通过适配器 notifyItemChanged() 更新回收器 套接字每秒发送许多数据，这意味着我每秒调用适配器多次 它可以工作，但是当更新更多次时会出现此错误

【问题讨论】：
【参考方案1】：经过多次搜索并尝试多种解决方案 最后我找到了解决方案 我将 ReyclerView 更改为 listView 并通过此代码更新我的列表
if (itemPos >= company_recycler.getFirstVisiblePosition() && itemPos-1<company_recycler.getLastVisiblePosition())
final View cell = company_recycler.getChildAt(itemPos - company_recycler.getFirstVisiblePosition() );
runOnUiThread(new Runnable()
@Override
public void run()
adapter.getView(itemPos-1, cell, company_recycler);
);
这对我来说很好
【讨论】：
不切换到列表视图是否可以解决此崩溃问题？以上是关于Android RecyclerView Adapter notifyItemChanged() 获取 IllegalStateException 已经在池中的主要内容，如果未能解决你的问题，请参考以下文章
