How I can Contains a listActivity class in a activity class?

Postby Jimmy Malibu » Fri Jul 25, 2008 8:25 pm

Hallo!

I have an activity class (Konsole) and an listActivity class (List5) and I'd like the list contain in the activity class.

i've tried something similar. this won't happen to work, because the ListActivity is designed to be an activity by itself. afaik there may only be one activity at a time.

workarounds:
you could access buttons via the menue and use the ListActivity as the main Activity.
or
you could use your buttons in the main activity and start you ListActivity as a SubActivity.


maybe you could dismantle some of the ListActivity-Layout and add it to your Konsole to do the work ?
