如何在Android上使用计时器进入recyclerView

为什么不帮助我呢？

在我的应用程序中，我希望在每个

recyclerView

项目中显示计时器
我用Kotlin语言写下面的代码，但是当滚动

recyclerView

计时器重置并且从开始时间重新开始时，不要继续
我的问题是计时器重置，我想在滚动

回收视图

项目时，计时器未重置，我想继续计时器

我的适配器代码：

class AuctionsTodayAdapter(val context: Context, val model: MutableList<AuctionsTodayResponse.Res.Today>) :
    RecyclerView.Adapter<AuctionsTodayAdapter.MyHolder>() {

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyHolder {
        val view = LayoutInflater.from(context).inflate(R.layout.row_bidzila_list, parent, false)
        return MyHolder(view)
    }

    override fun getItemCount(): Int {
        return model.size
    }

    override fun onBindViewHolder(holder: MyHolder, position: Int) {
        val modelUse = model[position]
        holder.setData(modelUse)
    }

    override fun onViewAttachedToWindow(holder: MyHolder) {
        val pos = holder.adapterPosition
        val modelUse = model[pos]
        holder.handler.post { holder.timer(modelUse.calculateEnd, 1000) }
    }

    override fun onViewDetachedFromWindow(holder: MyHolder) {
        if (holder.timmer != null) {
            holder.timmer.cancel()
        }
    }

    inner class MyHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {

        var handler = Handler(Looper.getMainLooper())
        lateinit var timmer: CountDownTimer

        fun setData(model: AuctionsTodayResponse.Res.Today) {
            model.image.let {
                Glide.with(context)
                    .load(Constants.BIDZILA_BASE_URL + it)
                    .apply(RequestOptions.diskCacheStrategyOf(DiskCacheStrategy.RESOURCE))
                    .into(itemView.rowBidzila_img)
            }
            model.title.let { itemView.rowBidzila_title.text = it }
        }

        fun timer(millisInFuture: Long, countDownInterval: Long): CountDownTimer {
            timmer = object : CountDownTimer(millisInFuture * 1000, countDownInterval) {
                override fun onTick(millisUntilFinished: Long) {
                    var seconds = (millisUntilFinished / 1000).toInt()
                    val hours = seconds / (60 * 60)
                    val tempMint = seconds - hours * 60 * 60
                    val minutes = tempMint / 60
                    seconds = tempMint - minutes * 60
                    itemView.rowBidzila_timer.rowBidzila_timer.text =
                        String.format("%02d", hours) + ":" + String.format(
                            "%02d",
                            minutes
                        ) + ":" + String.format("%02d", seconds)
                }

                override fun onFinish() {
                    itemView.rowBidzila_timer.rowBidzila_timer.text = "Finished"
                }
            }.start()

我如何修理它？

您可以使用模型。在这个模型中，你可以设置最后的计数值。在您的ViewHolder中，您将从模型的最后计算值开始计算时间。我希望您理解

这不是一个好的解决方案，但您可以使用

setIsRecycleable（false）

@KaranMer，我如何使用它？你能把我上面的代码寄给我吗？亲爱的朋友，我真的需要你的帮助，在oncreateviewholder中，你可以使用

holder.setIsRecyclable（false）找不到
holder
info
onCreateViewHolder
！使用你的viewholder对象谢谢亲爱的，但是你能帮我把上面的代码发给我吗？请亲爱的朋友，因为我是业余爱好者，真的需要你的帮助。请告诉我的朋友，我真的需要你的帮助，请把我上面的代码发给我。请谢谢，亲爱的。我会等你你在这里吗，我的朋友？你能帮助我吗？
