}

公共类MyAdapter扩展了RecyclerView.Adapter { 私有列表上下文； 私有列表myDataList； 公共MyAdapter（列表上下文）{ this.context=上下文； myDataList=新的ArrayList（）； } @凌驾 public ViewHolder onCreateViewHolder（视图组父级，int-viewType） { //替换为您的布局 View=LayoutFlater.from（parent.getContext（））.flate（R.layout.amount\u cart\u row，parent，false）； 返回新的ViewHolder（视图）； } @凌驾 公共无效onBindViewHolder（ViewHolder，int位置）{ //在此处将数据设置为布局组件。。 //获得金额 /*myDataList.get（position.getTestName（）； myDataList.get（position.getTestPrice（）*/ holder.testName.setText（myDataList.get（position.getTestName（））； holder.testPrice.setText（myDataList.get（position.getTestPrice（））； holder.textView2.setText（myDataList.get（position.getSerialNumber（））； } @凌驾 public int getItemCount（）{ /*如果（myDataList.size（）！=0）{ //如果列表不为空，返回列表大小！ 返回myDataList.size（）； } 返回0*/ 返回myDataList.size（）； } 公共void setMyDataList（列表myDataList）{ //正在从片段获取列表。 this.myDataList=myDataList； notifyDataSetChanged（）； } 公共类ViewHolder扩展了RecyclerView.ViewHolder{ TextView testName、testPrice、textView2； 公共视图持有者（视图项视图）{ 超级（项目视图）； //itemView.findViewById testName=itemView.findviewbyd（R.id.test\u name\u one）； testPrice=itemView.findviewbyd（R.id.test\u price）； textView2=itemView.findViewById（R.id.textView2）； } } } @凌驾 public void onBackPressed（）{ super.onBackPressed（）； 星触觉（新） 意图（AmountCartActivity.this，HealthServicesActivity.class））； 完成（）； } } 这是我的密码

在这里，我使用HealthActivity，在这个类中，通过使用recycler视图，我在recycler视图中显示了testList。我通过复选框选择testList，将其传递给recycler视图的AmountCartActivity，并且，我计算所选testList的总量，得到结果，并将结果传递给AmountCart活动通过bundle，我在bundle中得到正确的结果，但是，当我试图在textView中显示总量时，它什么也不显示

我的第二个问题是

我正在尝试将序列号显示到我的AmountCartActivity of recycler视图，无论我使用复选框从以前的HealthCartActivity中选择哪个。并且，我已经实现了一些代码，但我不知道如何解决它。请帮助我

第1期

数据应通过构造函数传递到适配器。问题可能只是向构造函数添加另一个参数：

public MyAdapter(List<AmountCartModel> context, List<AmountCartModel> myDataList) {
                    this.context = context;
                    myDataList = this.myDataList;

                }

公共MyAdapter（列表上下文，列表myDataList）{ this.context=上下文； myDataList=this.myDataList； } 或者

要将选择支持添加到

RecyclerView

实例，请执行以下操作：

• 确定要使用的选择键类型，然后构建一个

  ItemKeyProvider

• 实现

  ItemDetailsLookup

  ：它允许选择库访问给定动作的RecyclerView项的相关信息
