报错信息如下

我使用的是GridLayoutManager遇到的这种数组下标越界，于是我绞尽脑汁（其实也没有 哈哈哈），从网上搜寻为啥，找了半天，也没说因为个啥，就只有解决方案，如下：

 recyclerView.layoutManager = MyGridLayoutManager(activity, 6)

/**
 * 自己复写MyGridLayoutManager类，避免了由RecyclerView可能出现的holder数组越界Bug
 */

class MyGridLayoutManager(
    context: Context?,
    spanCount: Int

) : GridLayoutManager(context, spanCount) {

    override fun onLayoutChildren(
        recycler: Recycler,
        state: RecyclerView.State
    ) {
        try {
            super.onLayoutChildren(recycler, state)
        } catch (e: IndexOutOfBoundsException) {
            e.printStackTrace()
        }
    }
}
