使用setOnitemClick自定义适配器

Question

我有一个微调器包含三个选项＆＃34; ALL＆＃34;，＆＃34; PAYMENTS＆＃34;和＆＃34;费用＆＃34;。这些将显示3个列表视图。 ＆＃34; ALL＆＃34;选项将显示＆＃34; PAYMENT＆＃34;和＆＃34;费用＆＃34;。

我的问题是我想为这两个列表添加setOnItemClickListener。请参阅截图。每当我点击每个列表时，我都会传递某些值。每当我点击付款中的列表时，它将转到paymentdetails活动，每当点击列表中的费用时，它将转到费用明细活动。这应该与＆＃34; ALL＆＃34;相同。每个列表有三种不同的适配器（即ALL，PAYMENT和费用）。代码如下。

try {
    final JSONArray invoices = new JSONArray(common.json);
    if (invoices.length() == 0) {
        (rootView.findViewById(R.id.no_items)).setVisibility(View.VISIBLE);
        return;
    }
    final ArrayList<String[]> invoiceListData = new ArrayList<>();
    for (int i = 0; i < invoices.length(); i++) {
        JSONObject jsonObject1 = invoices.getJSONObject(i);
        String[] data = new String[9];
        data[0] = jsonObject1.getString("ID");
        data[1] = jsonObject1.getString("EntryNo");
        data[2] = jsonObject1.getString("Company");
        data[3] = jsonObject1.getString("Date");
        data[4] = jsonObject1.getString("PaymentMode");
        data[5] = jsonObject1.getString("Amount");
        data[6] = jsonObject1.getString("Type");
        data[7] = jsonObject1.getString("ApprovalDate");
        data[8] = jsonObject1.getString("GeneralNotes");
        invoiceListData.add(data);
    }
    adapter = new CustomAdapter(getContext(), invoiceListData, Common.PREVIOUSPAYMENTS);
    invoiceList.setAdapter(adapter);
    (rootView.findViewById(R.id.list_card)).setVisibility(View.VISIBLE);

    final ArrayList<String[]>PaymentListData=new ArrayList<>();
    final ArrayList<String[]>ExpenseListData=new ArrayList<>();

    for (int i = 0; i < invoiceListData.size(); i++) {
        if (invoiceListData.get(i)[6].equals("Payment")) {

            PaymentListData.add(invoiceListData.get(i));
            invoiceList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    Intent approvalDetailsIntent = new Intent(getContext(),ApprovalDetails.class);
                    approvalDetailsIntent.putExtra(Common.APPROVALID,invoiceListData.get(position)[0]);
                    approvalDetailsIntent.putExtra(Common.ENTRYNO,invoiceListData.get(position)[1]);
                    approvalDetailsIntent.putExtra(Common.PAYMENT_MODE,invoiceListData.get(position)[2]);
                    approvalDetailsIntent.putExtra(Common.PAYMENT_DATE,invoiceListData.get(position)[3]);
                    approvalDetailsIntent.putExtra(Common.AMOUNT,invoiceListData.get(position)[4]);
                    approvalDetailsIntent.putExtra(Common.COMPANY_DETAILS,invoiceListData.get(position)[5]);
                    approvalDetailsIntent.putExtra(Common.GENERAL_NOTES,invoiceListData.get(position)[8]);
                    startActivity(approvalDetailsIntent);
                }
            });
        } else if(invoiceListData.get(i)[6].equals("Expense")) {
           (rootView.findViewById(R.id.list_card)).setVisibility(View.VISIBLE);

            invoiceList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    Intent approvalDetailsIntent = new Intent(getContext(),ApprovalExpenseDetails.class);
                    approvalDetailsIntent.putExtra(Common.APPROVALID,ExpenseListData.get(position)[0]);
                    approvalDetailsIntent.putExtra(Common.REFNO,ExpenseListData.get(position)[1]);
                    startActivity(approvalDetailsIntent);
                }
            });
        }
    }

    Padapter = new CustomAdapter(getContext(),PaymentListData,Common.PREVIOUSPAYMENTS); //Global variable
    invoiceList.setAdapter(Padapter);
    (rootView.findViewById(R.id.list_card)).setVisibility(View.VISIBLE);
    Eadapter = new CustomAdapter(getContext(),ExpenseListData,Common.PREVIOUSPAYMENTS);
                    invoiceList.setAdapter(adapter);
    (rootView.findViewById(R.id.list_card)).setVisibility(View.VISIBLE);

    // Values passing for payments only.I dont know whether invoiceListData.get()..is correct or not.

    invoiceList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Intent approvalDetailsIntent=new Intent(getContext(),ApprovalDetails.class);

    //values passing for expense only
    invoiceList.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            startActivity(approvalDetailsIntent);
      }

Answer 1

您无法为列表中的项目设置onclicklistener！您必须为customAdapter中的每个视图设置onclicklistener

Answer 2

如果所有3种类型的数据类型相同，请遵循某些开发规则。

为数据创建POJO（模型）类。它可以帮助您以结构化的方式存储数据。

<强> InvoiceData.java

public class InvoiceData {

    private String Id;
    private String EntryNo;
    private String Company;
    private String Date;
    private String PaymentMode;
    private String Amount;
    private String Type; // "ALL", "Income", "Expense"
    private String ApprovalDate;
    private String GeneralNotes;

    public String getId() {
        return Id;
    }

    public void setId(String id) {
        Id = id;
    }

    public String getEntryNo() {
        return EntryNo;
    }

    public void setEntryNo(String entryNo) {
        EntryNo = entryNo;
    }

    public String getCompany() {
        return Company;
    }

    public void setCompany(String company) {
        Company = company;
    }

    public String getDate() {
        return Date;
    }

    public void setDate(String date) {
        Date = date;
    }

    public String getPaymentMode() {
        return PaymentMode;
    }

    public void setPaymentMode(String paymentMode) {
        PaymentMode = paymentMode;
    }

    public String getAmount() {
        return Amount;
    }

    public void setAmount(String amount) {
        Amount = amount;
    }

    public String getType() {
        return Type;
    }

    public void setType(String type) {
        Type = type;
    }

    public String getApprovalDate() {
        return ApprovalDate;
    }

    public void setApprovalDate(String approvalDate) {
        ApprovalDate = approvalDate;
    }

    public String getGeneralNotes() {
        return GeneralNotes;
    }

    public void setGeneralNotes(String generalNotes) {
        GeneralNotes = generalNotes;
    }
}

使用模型

设置这样的数据

final ArrayList<InvoiceData> invoiceListData = new ArrayList<>();

JSONObject jsonObject1;

InvoiceData rowObject;

for (int i = 0; i < invoices.length(); i++) {

    jsonObject1 = invoices.getJSONObject(i);

    rowObject = new InvoiceData();

    rowObject.setId(jsonObject1.getString("ID"));
    rowObject.setEntryNo(jsonObject1.getString("EntryNo"));
    rowObject.setCompany(jsonObject1.getString("Company"));
    rowObject.setDate(jsonObject1.getString("Date"));
    rowObject.setPaymentMode(jsonObject1.getString("PaymentMode"));
    rowObject.setAmount(jsonObject1.getString("Amount"));
    rowObject.setApprovalDate(jsonObject1.getString("ApprovalDate"));
    rowObject.setGeneralNotes(jsonObject1.getString("GeneralNotes"));
    rowObject.setType("Expense");

    invoiceListData.add(rowObject);
}

adapter = new CustomAdapter(getContext(), invoiceListData, Common.PREVIOUSPAYMENTS);

invoiceList.setAdapter(adapter);

并在Listview上设置项目点击监听器（确保它是listview b'z recycleler视图没有这样的方法）

invoiceList.setOnItemClickListener(new OnItemClickListener()
{
    @Override 
    public void onItemClick(AdapterView<?> arg0, View arg1,int position, long arg3)
    { 
        InvoiceData rowObject = adapter.getItem(position);

        if(rowObject != null) {

            if(rowObject.getType().equals("Expense")) {
                // write different code for Expense here

            } else if(rowObject.getType().equals("Income")) {
                // write different code for Income here
            }


        }

    }
});

希望这会有所帮助......
