android – 在滚动RecyclerView时发生很奇怪的事情

概述我正在使用RecyclerView一个长列表,当我滚动太快,有些奇怪的事情发生.有两个问题. 第一个是下图中的一个.项目之一(如图像中的红色边框)粘在屏幕的某个随机部分,并阻止其他项目.当该项目的真实版本在屏幕上可见时,它将消失. 滚动这个长的RecyclerView太快的另一个问题是粘贴onClick效果.一些项目变得可见,就像有人在按压它们. 有关我的适配器的这些问题,还是RecyclerVi 我正在使用RecyclerVIEw一个长列表,当我滚动太快,有些奇怪的事情发生.有两个问题.

第一个是下图中的一个.项目之一(如图像中的红色边框)粘在屏幕的某个随机部分,并阻止其他项目.当该项目的真实版本在屏幕上可见时,它将消失.

滚动这个长的RecyclerVIEw太快的另一个问题是粘贴onClick效果.一些项目变得可见,就像有人在按压它们.

有关我的适配器的这些问题,还是RecyclerVIEw的常见问题？这是我的适配器

       }    }}

解决方法 这是解决我的问题：

动画在某种程度上导致RecyclerVIEw出现问题.所以我的解决方案是删除以下行：

setAnimation(holder.itemVIEw,position);

我没有尝试再次添加动画,但如果你真的需要它,这里有一些有用的东西：How to animate RecyclerView items when they appear.
