我将数据显示在ListView中，如以下代码所示：
private class OrderAdapter extends ArrayAdapter<Employer> {
private ArrayList<Employer> items;
public OrderAdapter(Context context, int textViewResourceId, ArrayList<Employer> items) {
super(context, textViewResourceId, items);
this.items = items;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.paye_list_row, null);
}
Employer o = items.get(position);
if (o != null) {
TextView tt = (TextView) v.findViewById(R.id.toptext);
TextView bt = (TextView) v.findViewById(R.id.value);
if (tt != null) {
tt.setText(o.getOrderName()); // Setting the Value here
}
if(bt != null){
if(position==0)
bt.setText(o.getTaxcode()); // Setting the Value here
if(position==1)
bt.setText(o.getPayPeriod()); // Setting the Value here
if(position==2)
bt.setText(o.getPayFrequency()); // Setting the Value here
if(position==3)
bt.setText(o.getSalaryWage()); // Setting the Value here
if(position==4)
bt.setText(o.getNetGrossAmount()); // Setting the Value here
if(position==5)
bt.setText(o.getKiwiSaverMember()); // Setting the Value here
if(position==6)
bt.setText(o.getEmployeeDeduction()); // Setting the Value here
if(position==7)
bt.setText(o.getEmployeeContribution()); // Setting the Value here
if(position==8)
bt.setText(o.getComplyingFundMember()); // Setting the Value here
if(position==9)
bt.setText(o.getFundContribution()); // Setting the Value here
if(position==10)
bt.setText(o.getESCTTaxRate()); // Setting the Value here
if(position==11)
bt.setText(o.getChildSupportDeduction()); // Setting the Value here
if(position==12)
bt.setText(o.getPayrollDonation()); // Setting the Value here
}
}
return v;
}
}
我将数据手动添加到我的另一个ArrayList中，如下代码：
// Set Employee one by one
ArrayList<Employer> tempEmployerList = employerList;
System.out.println("=================================" +
"=IN end Document================================");
System.out.println(" tempEmployerList Size:" +tempEmployerList.size());
Employer m = new Employer();
// My Code for to add data
m = new Employer();
m.setTaxcode(taxCodeValue);
m.setPayPeriod(payPeriodValue);
m.setPayFrequency(payFrequencyValue);
m.setSalaryWage(salaryWageValue);
m.setNetGrossAmount("Gross");
m.setKiwiSaverMember(kiwiSaverMemberValue);
m.setEmployeeDeduction(employeeDeductionValue);
m .setEmployeeContribution(employeeContributionValue);
m.setComplyingFundMember(complyingFundMemberValue);
m.setFundContribution(fundContributionValue);
m.setESCTTaxRate(ESCTTaxRateValue);
m.setChildSupportDeduction(childSupportDeductionValue);
m.setPayrollDonation(payrollDonationValue);
employerList.add(m);
如果我想在日志猫中显示该数据，则可以通过以下代码看到它：
// TO DISPLAY DATA
for(int j=0;j<tempEmployerList.size();j++)
{
System.out.println("================ Employee: "+(j+1)+"======================");
m = new Employer();
m=tempEmployerList.get(j);
//System.out.println("TaxCodeHeading: "+(j+1)+" = "+m.getOrderName());
System.out.println("TaxCode: "+(j+1)+" = "+m.getTaxcode());
System.out.println("PayPeriod: "+(j+1)+" = "+m.getPayPeriod());
System.out.println("Frequency: "+(j+1)+" = "+m.getPayFrequency());
System.out.println("Salary/Wage: "+(j+1)+" = "+m.getSalaryWage());
System.out.println("NetGross Amount: "+(j+1)+" = "+m.getNetGrossAmount());
System.out.println("KiwiSaverMember: "+(j+1)+" = "+m.getKiwiSaverMember());
System.out.println("Employee Deduction: "+(j+1)+" = "+m.getEmployeeDeduction());
System.out.println("Complying Fund Member: "+(j+1)+" = "+m.getComplyingFundMember());
System.out.println("Fund Contribution: "+(j+1)+" = "+m.getFundContribution());
System.out.println("ESCT Tax Rate: "+(j+1)+" = "+m.getESCTTaxRate());
System.out.println("Child Support Deduction: "+(j+1)+" = "+m.getChildSupportDeduction());
System.out.println("Payroll giving Donation: "+(j+1)+" = "+m.getPayrollDonation());
}
一切正常。但是现在，如果我添加了更多的员工，那么我想在单击下一步按钮时将其一一显示在列表视图中。
那么怎么可能。
请帮我。
谢谢。
最佳答案
在下一个和上一个按钮事件将Employer对象更改为列表中的下一个或上一个项目的情况下，将一个Employee对象声明为Activity中的一个字段，并从该字段加载您的适配器数据，并调用adapter.notifyDataSetChanged（）方法。
