塊引用我正在嘗試實現(xiàn)自動滾動無限 recyclerview，就像 hotstar 在 hotstar VIP 訂閱頁面中擁有它一樣。我試過給定的代碼。對于自動滾動回收器：-binding.rvPartyOfWeek.addOnScrollListener（CustomScrollListener（））private val SCROLLING_RUNNABLE = object : Runnable { override fun run() { val duration = 10 val pixelsToMove = 22 if (!isPartyOfWeekScrolling) { binding.rvPartyOfWeek.smoothScrollBy(pixelsToMove, 0) } mHandler.postDelayed(this, duration.toLong()) }}對于無限滾動：-binding.rvPartyOfWeek.addOnScrollListener(object : RecyclerView.OnScrollListener() { override fun onScrolled(recyclerView2: RecyclerView, dx: Int, dy: Int) { super.onScrolled(recyclerView2, dx, dy) val totalItemCount = layoutManagerparty.itemCount val lastVisibleItem = layoutManagerparty.findLastVisibleItemPosition() if (totalItemCount <= (lastVisibleItem + 3)) { if (totalItemCount > 22) { for (i in 0..10) { listParty.removeAt(0) } } listParty.addAll(listPartySingle) adapterpartyofweek.notifyDataSetChanged() Log.i("Helllo listParty", listParty.size.toString()) } } })它在某些設(shè)備上滾動不流暢，在某些舊設(shè)備上崩潰。

我做了如下：
為 RecyclerView 創(chuàng)建自動滾動
`
private fun autoScroll() {
scrollCount = 0;
var speedScroll: Long = 1200;
val runnable = object : Runnable {
override fun run() {
if (layoutManager.findFirstVisibleItemPosition() >= imageArrayList.size / 2) {
adapter.load()
}
recyclerView.smoothScrollToPosition(scrollCount++)
Log.e(TAG, "run: $scrollCount")
handler.postDelayed(this, speedScroll)
}
}
handler.postDelayed(runnable, speedScroll)
}
`
自動創(chuàng)建平滑滾動
`
layoutManager = object : LinearLayoutManager(this@MainActivity) {
override fun smoothScrollToPosition(recyclerView: RecyclerView, state: RecyclerView.State?, position: Int) {
val smoothScroller = object : LinearSmoothScroller(this@MainActivity) {
override fun calculateSpeedPerPixel(displayMetrics: DisplayMetrics?): Float {
return 5.0f;
}
}
smoothScroller.targetPosition = position
startSmoothScroll(smoothScroller)
}
}
`
