class HomeCategoryAdapter(private val items: List<IconModel>) : RecyclerView.Adapter<HomeCategoryAdapter.ViewHolder>() {

        /// 设置事件监听，这里是为了处理NestedScrollView嵌套RecyclerView视图点击事件冲突问题，所以取消时ACTION_CANCEL也进行回调

                MotionEvent.ACTION_UP -> {

                    item.click()
                    false // 返回 false 让事件继续传递给 setOnClickListener
                }
                MotionEvent.ACTION_CANCEL -> {
                    NSLog("手指事件取消")
                    item.click()
                    false // 返回 false 让事件继续传递
                }
                else -> {
                    NSLog("else event.action=${event.action}")
                    false
                }
            }
        }
    }

    override fun getItemCount(): Int = items.size
}

布局：

// 禁用 RecyclerView 的嵌套滚动
//home_fun_rv.isNestedScrollingEnabled = false
// 设置 LayoutManager
home_fun_rv.layoutManager = StaggeredGridLayoutManager(5, StaggeredGridLayoutManager.VERTICAL)
// 初始化适配器
cateAdapter = HomeCategoryAdapter(tempArr)
// 设置适配器
home_fun_rv.adapter = cateAdapter
