My Application has like below functionality:
I have Done to set the Values with the custom adapter. but now i want to implement the functionality as like add another data, delete showing data, go to next data and back to previous data. In all that functionality only the Blue Values should be change. (that is the orderStatus in code). Left One Value (orderName()) should remain the same. Then how to implement that ?
If i am adding the new data then that should be temporary stored as i want to show that data in to report.
In My Application i am going to add data first time AS like below code:
getOrder function to set the Value of the OrderName and OrderStatus.
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();

// 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();
}
};
And Creating and calling the thread like this:
viewOrders = new Runnable(){
@Override
public void run() {
getOrders();
}
};
thread = new Thread(null, viewOrders, "MagentoBackground");
thread.start();
So Will please help me to give logic for that or give some code that can help me in this to implement that functionality.
Thanks.
On the basis of your question
Here is my answer in few steps and assuming that you are passing your list values in var ‘A’:
1. You should extend
BaseAdapterin yourcustom adapterof the list.2. Set your initial values to
Aand pass it to theadapterandset it to the listview.3. Now if you want to add some more values then
add it in your var Aandcall thenotifyDataSetChanged()which will reflect your new values to the list.4. If you want to show next values then also set the appropriate values in A and call
notifyDataSetChanged().5. If you want to delete then
setOnItemClickListener()to your list and on click remove the values from theAand callnotifyDataSetChanged().Note: To save the list values you can use SQLite. You can follow this tutorial over lisview.
