The problem that am facing is with the from-to date and time dialog’s. I have created all of them separate.
On onCreate i have set the current date and time on the dialog’s for the user. i.e for eg 24/7/2012 as todays date. When ever i change/click on the dialog for the from_date to the date for eg: 26/7/2012 then i have change the text of the to_date dialog to 26/7/2012 via setText. The issue that comes here is when i open the to_date dialog the date that appears in the dialog is 24/7/2012 and not 26/7/2012. How can this be achieved same for date and time picker dialog. I have attached the code below.
Thanks in advance.
public Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID_FROM:
Log.i("Date Case", "" + from_day);
return new DatePickerDialog(this, dateListenerfrom, from_year,
from_month, from_day);
case DATE_DIALOG_ID_TO:
Log.i("Date Case", "" + to_day);
return new DatePickerDialog(this, dateListenerto, to_year,
to_month, to_day);
case TIME_DIALOG_ID_FROM:
return new TimePickerDialog(this, timeListenerfrom, from_hours,
from_min, false);
case TIME_DIALOG_ID_TO:
return new TimePickerDialog(this, timeListenerto, to_hours, to_min,
false);
}
return null;

This is onClick
{
if (v == from_date) {
showDialog(DATE_DIALOG_ID_FROM);
}
if (v == to_date) {
showDialog(DATE_DIALOG_ID_TO);
}
if (v == from_time) {
showDialog(TIME_DIALOG_ID_FROM);
}
if (v == to_time) {
showDialog(TIME_DIALOG_ID_TO);
}
}
You have to implement the Below method in your Activity to update the Date/Time to be shown in the Dialog Box.
