无论我使用复选框从以前的HealthCartActivity中选择的哪个，我都尝试在我的Recycler视图的AmountCartActivity中显示序列号。而且，我已经实现了一些代码，但是我没有获得序列号。

Answer 1

您必须在serialNumber上添加AmountCartModel。这样可以解决您的问题

Answer 2

如下所示在您的AmountCartModel中放置一个ID；

limit

然后从每个视图检索此序列号。由于您要发送意图表单onBackPressed（）;将该列表作为附加内容附加到意图上，

[
  {
    $group: {
      _id: "$myDoc,homepage_domain",
      count: {$sum: 1},
      entry: {
        $push: {
          location_city: "$myDoc.location_city",
          homepage_domain: "$myDoc.homepage_domain",
          country: "$myDoc.country",
          employee_linkedin: "$myDoc.employee_linkedin",
          linkedin_url: "$myDoc.inkedin_url",
          homepage_url: "$myDoc.homepage_url",
          industry: "$myDoc.industry",
          read_at: "$myDoc.read_at"
        }
      }
    }
  }, {
    $limit : 50000
  }, {
    $skip: 50000
  }
],
{
  allowDiskUse: true
},
print(
  db.Or9.insert({
    "HomepageDomain":myDoc.homepage_domain,
    "location_city":myDoc.location_city
  })
)

请确保您要从中扩展列表的对象（AmountCarModel）扩展了Parcelable，并在onResume（）的HealthServiceActivity中捕获它

或者，也许是最好的方法，是在如下所示的Retrofit onResponse（）方法中将序列号附加到HealthServiceActivity内；

public class AmountCartModel {

private int serialNumber; // add this line
private String testName;
private String testPrice;
private Integer totalPrice;


public AmountCartModel() {
    this.serialNumber= serialNumber; // add this line
    this.testName = testName;
    this.testPrice = testPrice;
    this.totalPrice = totalPrice;
}

public int getSerialNumber (){
} // add this line

public void setSerialNumber(int serialNumber) {
}// add this line also

Answer 3

好吧，您可以解决。而且您不必仅在模型中保留serialNumber变量即可跟踪其位置。

您可以将position的{{1}}参数变量用于序列号和计数。

即

onBindViewHolder()

Answer 4

在AmountCartModel中，serialNumber的数据类型为String

在放置对象的同时进行设置计数= extras.getInt（“ serialNumber”）;

        //Just add your data in list
        AmountCartModel mydata = new AmountCartModel();  // object of Model Class
        mydata.setTestName(testName );
        mydata.setTestPrice(testPrice);

        mydata.setTotalPrice(Integer.valueOf(totalPrice));

        mydata.setSerialNumber(counting);

并且您将其存储在ArrayList中，而没有for循环，因此每次只有一个对象包含在您的arraylist中

Answer 5

尝试这种方式

int count = 0;
@Override
    public void onClick(View v) {

        switch (v.getId()) {

                    case R.id.submit_button:

                        int totalAmount = 0;
                        int totalPrice = 0;
                        String testName = "";
                        String testPrice="";




                        List<TestListModel> stList = ((RecyclerAdapter) madapter)
                                .getTestList();


                       for (int i = 0; i < stList.size(); i++) {
                            TestListModel singleStudent = stList.get(i);

                           //AmountCartModel serialNumber = stList.get(i);


                           if (singleStudent.isSelected() == true) {

                                testName = testName + "\n" + singleStudent.getTest_name().toString();
                                testPrice = testPrice+"\n" + singleStudent.getTest_price().toString();


                                count++;

                                totalAmount = Integer.parseInt(stList.get(i).getTest_price());

                                totalPrice = totalPrice + totalAmount;

                            }
                       }


                        Toast.makeText(HealthServicesActivity.this,
                                "Selected Lists: \n" + testName+ "" + testPrice, Toast.LENGTH_LONG)

                        Intent in= new Intent(HealthServicesActivity.this, AmountCartActivity.class);

                        in.putExtra("test_name", testName);
                        in.putExtra("test_price", testPrice);

Answer 6

我找到了答案。我已经完成了如下序列号的代码。在这里，我在元素前面得到序列号。在此代码中，我获取了一个int变量并使用值1进行了初始化。此后，我在for循环中调用srNo变量，然后在for循环的末尾递增。

                    int srNo = 1;

                    List<TestListModel> stList = ((RecyclerAdapter) madapter)
                            .getTestList();


                   for (int i = 0; i < stList.size(); i++) {
                        TestListModel singleStudent = stList.get(i);

                       if (singleStudent.isSelected() == true) {


                           testListId = testListId+ "\n" + Integer.parseInt(String.valueOf(srNo));

                           testName = testName + "\n" + singleStudent.getTest_name().toString();
                           testPrice = testPrice+"\n" + singleStudent.getTest_price().toString();

                           srNo++;

                            totalAmount = Integer.parseInt(stList.get(i).getTest_price());

                            totalPrice = totalPrice + totalAmount;


                        }
                   }

Answer 7

@Override
    public void onBindViewHolder(ViewHolder holder, int position) 
    holder.id.setText(String.valueOf(" "+(position+1)));

使用上述方法。
