Android: use a datepicker and timepicker from within a Dialog

Question

Hello, I am facing a problem I do not know how to solve... I have an activity, when I click on a particuliar item of the menu linked to this activity, a dialog is displayed and used to add an item. This item has a date and a time, but I do not manage to have a DatePicker and TimePicker within this dialog. I also try passing the activity to the dialog and use this one to display the datepicker., but that does not work. Before this, I handled the creation of such items within another Activity. In this case, it works fine. But I found the Dialog sexier... :-) Would you have any ideas ? Hope I am not too confused..... thanks a lot, Luc

I edit this post to share the code I have difficulties with.

I have a basic Dialog class that tried to use DatePicker and TimePicker. Basically, Eclipse complains that:

• the showDialog is undefined for View.OnClickListener()
• onCreateDialog method: The method onCreateDialog(int) of type EventCreateDialog must override or implement a supertype method
• DatePickerDialog is undefined (as this is not an acitvity)

All this stuff works from within an Activity but I cannot have it working from a Dialog.

Thanks a lot, Luc
