Android错误：我在折叠单元格上存在问题，该问题在单击并显示时没有动画？

Question

我希望使用此代码不会在点击时折叠动画。跳过动画时，打开时没有动画  Xml：

    <com.ramotion.foldingcell.FoldingCell xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:folding-cell="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        folding-cell:additionalFlipsCount="2"
        folding-cell:animationDuration="1000"
        folding-cell:backSideColor="@color/bgBackSideColor"
        folding-cell:cameraHeight="30">

错误：
