RecycerView在滚动到特定位置时崩溃

Question

我有RecycerView，它有分页，当我滚动一些时候，它正在崩溃。当我慢慢滚动时，它没有崩溃。我已经提供了适配器和活动代码。请让我知道我在这里做错了什么。我已经搜索了相同的问题，但无法在此处捕获错误。

应用程序正在崩溃的内存管理失败，这里的每个项目都分配动画，应用动画不清楚。我已经解决了你的问题花了一天，它为我工作。

@Override public void onViewDetachedFromWindow(ViewHolder holder) { 
super.onViewDetachedFromWindow(holder);
 ((ViewHolder)holder).clearAnimation();
 } 

在我的ViewHolder added方法中：

public void clearAnimation() { 
itemView.clearAnimation(); 
}
