直升机家伙得到了最后一个问题与我的回收站和这里的事情，Recyclerview将不保存更改的项目的第一个和最后一个数据位置
当我点击该按钮，相应的监听器会改变按钮的颜色，并设置启用为false，这是完美的工作，并在大量的数据运行说，从0到99从1到98的视图将保持按钮的颜色和启用设置为false，但位置0和99将不会粘贴适配器，并会apreciate如果你们中的任何人可以帮助找到问题是什么..或者如果我需要改变一些recyclerview设置，我不知道..反正先谢谢你的帮助。

我会建议你启用的状态存储在您的viewHolder状态，并相应地设置在按钮状态的'onBindViewHolder'。按照相同的背景颜色模式。关键在于，随着所有的回收和物料的继续，最好是控制每个物品的状态，而不是依赖Recyclerview。只是补充一点，我对第一个项目有类似的问题，并且调试意识到对于第一个视图'onBindViewHolder'被多次调用，并且它已经有一段时间了。 – Dibzmania
听起来不错，会尝试并报告回来。 –
