Android开发recyclerView监听滑动距离，超过多少

直接上代码吧，应该你们也看得懂。

val scrollDistance = CUtils.getScreenHeightPx(mContext)/2
    mBinding.srrvDatas.recyclerView.addOnScrollListener(object :RecyclerView.OnScrollListener(){

        override fun onScrollStateChanged(recyclerView: RecyclerView, newState: Int) {
            super.onScrollStateChanged(recyclerView, newState)
        }

        override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
            super.onScrolled(recyclerView, dx, dy)
            // dy > 0 时为向上滚动
            // dy < 0 时为向下滚动
            scrollY += dy
            LogUtils.i("onScrolled","onScrolled")
            dealBaiduMatchTip(scrollY >= scrollDistance && MyApplication.currentUserInfo?.baiduMatchState != 1)

        }
    })

dealBaiduMatchTip方法参数就是个布尔值show。代码中scrollY定义在类变量即可
