使用水平滚动设置六边形形状

Question

我正在尝试在水平滚动中设置六边形列表，但没有完成，如何解决？

override fun onBindViewHolder(holder: MyViewholder, position: Int) {

    val pos = position + 1
    val topMargin: Int = pxFromDp(holder.textView.getContext(), -17.toFloat())
    val leftMargin: Int = pxFromDp(holder.textView.getContext(), 51.toFloat()) //3 times of 17

    val param = holder.textView.getLayoutParams() as GridLayoutManager.LayoutParams
    if (pos < 4) {
        param.setMargins(0, 0, 0, 0)
    } else if ((pos + 1) % 5 == 0 || pos % 5 == 0) {
        param.setMargins(0, topMargin, 0, 0)
    } else {
        param.setMargins(0, topMargin, 0, 0)
    }
    holder.textView.setLayoutParams(param)
}
