Hi,
I am interested to have tabpanel for my application. I have achieved this by
inheriting the class TabActivity. Now I want each sub-sequent activity
should have the same tabpanel and from R & D, I came to know that this is
possible by using ActivityGroup.
I have followed below steps
1) Created the TabActivity which has two tabs.
2) one of the activity from these tab, I have inherited from ActivityGroup.
3) Now I am intrested to open a child activity inside this activity.
To do this I have used below code
var intent = new Intent();
intent.SetClass(Parent, typeof(Activity1));
View childView =
this.LocalActivityManager.StartActivity("SubscriptionActivity",
intent).DecorView;
this.SetContentView(childView);
4) On Activity1 page, I have one spinner control. I have populated/declared
as below
Spinner spinner = FindViewById<Spinner>(Resource.Id.spinner);
spinner.ItemSelected += new
EventHandler<ItemEventArgs>(spinner_ItemSelected);
var adapter = ArrayAdapter.CreateFromResource(Parent,
Resource.Array.planets_array, Android.Resource.Layout.SimpleSpinnerItem);
adapter.SetDropDownViewResource(Android.Resource.Layout.SimpleSpinnerDropDownItem);
spinner.Adapter = adapter;
The above steps populate the spinner value correctly but when I tried to
change value by tapping over the spinner control it gives below issue.
W/WindowManager( 44): Attempted to add application window with unknown

I think this issue is with the context I am providing to the spinner
control. But I am unable to solve it.
Please help me with suggestion or code samples or please tell me how to use
spinner control in child activity or activitygroup.
Thanks,
Nilesh
