recyclerview 中没有静态方法 clearInterpolator
No static method clearInterpolator in recyclerview
我尝试将项目插入 recyclerView，但是当我使用 notifyItemInserted 对其进行动画处理时，我面临强制关闭并且消息是 recyclerview 中没有静态方法 clearInterpolator。我不知道那是什么意思。
在此先感谢您的帮助

我觉得你介绍Recycleriew之前应该已经写了很久了。
需要同时更新兼容包
例如：
之前
compile 'com.android.support:appcompat-v7:23.4.0'
现在
compile 'com.android.support:recyclerview-v7:24.2.0'
compile 'com.android.support:appcompat-v7:24.2.0'
注意版本号后面的分号。
