Hi,
I'm trying to recreate the UI screen called 'My Places' that is used
in the Weather Channel app. I'd attach a screenshot of it but I'm not
sure if I can when posting here. It seems they're using two listviews
one on top of the other, but I'm not sure for certain. Could anybody
confirm this for me? If they are doing this, how is this done? I've
tried to implement this, but without full success. My top listview
'Add a place' 'comes up correctly, but the bottom listview will not
appear/populate for me? I shall attach my code so far......
Any help would be greatly appreciated.
Thanks
Simon
