【问题描述】：
我的应用程序具有以下功能：
我已经完成了使用自定义适配器设置值。但现在我想实现功能，比如添加另一个数据、删除显示数据、转到下一个数据并返回到以前的数据。在所有这些功能中，只有蓝色值应该改变。 （即代码中的 orderStatus）。左一个值 (orderName()) 应该保持不变。那么如何实现呢？
如果我要添加新数据，则应将其临时存储，因为我想在报告中显示该数据。
在我的应用程序中，我将首次添加数据，如下代码：
getOrder函数设置OrderName和OrderStatus的Value。
public void getOrders(){
try{
// if(employee)
// {
System.out.println("You are in Employee");
m_orders = new ArrayList<Order>();
payListForEmployee = new String[] {"Tax Code","Pay period Begin","Pay Frequency","Salary/Wage per pay",
"Net or Gross Amount","KS Employee deduction","KS Employee contributions","Child Support deduction","Payroll giving donation"};
Order o[]=new Order[payListForEmployee.length];
System.out.println("The Length is: "+payListForEmployee.length);
for (int i = 0; i < payListForEmployee.length; i++)
{
o[i]=new Order();
o[i].setOrderName(payListForEmployee[i]);
//myPrefs = this.getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
// for TAXCODE
if(i==0) {
taxCodeValue = PAYEEmployeeDetail.taxCodeFinalValue;
if((taxCodeValue==null)) {
taxCodeValue = "Please select";
}
o[i].setOrderStatus(taxCodeValue);
//System.out.println("The Value is: "+o[i].getOrderStatus());
}
// for Pay Period Frequency
if(i==1) {
//payPeriodValue = myPrefs.getString("payperiod", "12 09 2011");
payPeriodValue = PAYEEmployeeDetail.payPeriodFinalValue;
if((payPeriodValue==null)) {
payPeriodValue = "--/--/----";
}
o[i].setOrderStatus(payPeriodValue);
//System.out.println("The Value is: "+o[i].getOrderStatus());
}
// for Pay frequency
if(i==2) {
//payFrequencyValue = myPrefs.getString("payfrequency", "Weekly");
payFrequencyValue = PAYEEmployeeDetail.payFrequencyFinalValue;
if((payFrequencyValue==null)) {
payFrequencyValue = "Please select";
}
o[i].setOrderStatus(payFrequencyValue);
//System.out.println("The Value is: "+o[i].getOrderStatus());
}
// for salary / wage
if(i==3) {
salaryWageValue = PAYEEmployeeDetail.salaryWageFinalValue;
if((salaryWageValue==null)||(salaryWageValue.equals(""))) {
salaryWageValue = "$0";
}
else{
salaryWageValue = "$"+salaryWageValue;
}
o[i].setOrderStatus(salaryWageValue);
//System.out.println("The Value is: "+o[i].getOrderStatus());
}
// For Gross / Net
if(i==4) {
o[i].setOrderStatus("Gross");
//System.out.println("The Value is: "+o[i].getOrderStatus());
}
// for KS Employee Deduction
if(i==5) {
employeeDeductionValue = PAYEEmployeeDetail.employeeDeductionFinalValue;
if((employeeDeductionValue==null)||(employeeDeductionValue.equals(""))) {
employeeDeductionValue = "0%";
}
o[i].setOrderStatus(employeeDeductionValue);
//System.out.println("The Value is: "+o[i].getOrderStatus());
}
// for KS Employee Contribution
if(i==6) {
employeeContributionValue = PAYEEmployeeDetail.employeeContributionFinalValue;
if((employeeContributionValue==null)||(employeeContributionValue.equals(""))) {
employeeContributionValue = "0%";
}
else{
employeeContributionValue = employeeContributionValue+"%";
}
o[i].setOrderStatus(employeeContributionValue);
//System.out.println("The Value is: "+o[i].getOrderStatus());
}
// for Child Support Deduction
if(i==7) {
childSupportDeductionValue = PAYEEmployeeDetail.childSupportDeductionFinalValue;
if((childSupportDeductionValue==null)||(childSupportDeductionValue.equals(""))) {
childSupportDeductionValue = "$0";
}
else{
childSupportDeductionValue = "$"+childSupportDeductionValue;
}
o[i].setOrderStatus(childSupportDeductionValue);
//System.out.println("The Value is: "+o[i].getOrderStatus());
}
// for Payroll giving donation
if(i==8) {
payrollDonationValue = PAYEEmployeeDetail.payrollDonationFinalValue;
if((payrollDonationValue==null)||(payrollDonationValue.equals(""))) {
payrollDonationValue = "$0";
}
else{
payrollDonationValue = "$"+payrollDonationValue;
}
o[i].setOrderStatus(payrollDonationValue);
//System.out.println("The Value is: "+o[i].getOrderStatus());
}
m_orders.add(o[i]);
//lv.invalidate();
// System.out.println("==> TaXCode Value: "+PAYEEmployeeDetail.taxCodeFinalValue);
// System.out.println("==> PAyPeriod Value: "+PAYEEmployeeDetail.payPeriodFinalValue);
// System.out.println("==> PayFrequency Value: "+PAYEEmployeeDetail.payFrequencyFinalValue);
// System.out.println("==> Salary/Wage Value: "+PAYEEmployeeDetail.salaryWageFinalValue);
// System.out.println("==> Gross/Net Value "+"STATIC VALUE = GROSS");
// System.out.println("==> Employee Deduction Value "+PAYEEmployeeDetail.employeeDeductionFinalValue);
// System.out.println("==> Employee Contribution Value "+PAYEEmployeeDetail.employeeContributionFinalValue);
// System.out.println("==> Child Support Deduction Value "+PAYEEmployeeDetail.childSupportDeductionFinalValue);
// System.out.println("==> PayRoll Donation Value "+PAYEEmployeeDetail.payrollDonationFinalValue);
//
}
// }
// else
// {
// System.out.println("You Are in Employer");
// m_orders = new ArrayList<Order>();
//
// payListForEmployer = new String[] {"Tax Code","Pay period Begin","Pay Frequency","Salary/Wage per pay",
// "Net or Gross Amount","KiwiSaver Member","Employee Deduction","Employee Contributions",
// "Complying Fund Member","Fund Contribution","ESCT Tax Rate","Child Support Deduction","Payroll giving donation"};
//
// System.out.println("The Length is: "+payListForEmployer.length);
//
// Order o[]=new Order[payListForEmployer.length];
// for (int i = 0; i < payListForEmployer.length; i++)
// {
// o[i]=new Order();
// o[i].setOrderName(payListForEmployer[i]);
// o[i].setOrderStatus("Pending");
// m_orders.add(o[i]);
// }
// }
Thread.sleep(100);
Log.i("ARRAY", ""+ m_orders.size());
} catch (Exception e) {
e.printStackTrace();
}
runOnUiThread(returnRes);
}
private Runnable returnRes = new Runnable() {
@Override
public void run() {
if(m_orders != null && m_orders.size() > 0){
m_adapter.notifyDataSetChanged();
for(int i=0;i<m_orders.size();i++)
m_adapter.add(m_orders.get(i));
}
// m_ProgressDialog.dismiss();
m_adapter.notifyDataSetChanged();
}
};
然后像这样创建和调用线程：
viewOrders = new Runnable(){
@Override
public void run() {
getOrders();
}
};
thread = new Thread(null, viewOrders, "MagentoBackground");
thread.start();
所以请帮助我为此提供逻辑或提供一些可以帮助我实现该功能的代码。 谢谢。
