Android 开发中实现 RecyclerView 触控滑块到达屏幕底部边缘的自定义 listeners 逻辑

 recyclerview.addOnScrollListener(object: RecyclerView.OnScrollListener() {

    
         override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
    
             super.onScrolled(recyclerView, dx, dy)
    
             if (isSlideToBottom(recyclerView)) {
    
                 //滑动到底部了

         }
    
     })
    
     }
    
  
    
     private fun isSlideToBottom(rv: RecyclerView?): Boolean {
    
     if (rv == null) return false
    
     return rv.comp
