I have an ArrayAdapter<int> as a datasource to a spinner. The code blows up
|
|
when the adapter tries to get an item. It seems like it works if T is a
|
|
string but not if T is an int. This was working previously for sure.
|
|
|
|
Sample project attached.
|
|
|
|
Here is the log
|
|
|
|
I/test (19493): string : val = 1,SelectedItemPosition = 0,v.Adapter is
|
|
null : False
|
|
I/test (19493): string: Adapter.Count = 12
|
|
I/test (19493): string: Adapter.GetItem(0)
|
|
I/test (19493): after string selection
|
|
I/test (19493): val = 1,SelectedItemPosition = 0,v.Adapter is null :
|
|
False
|
|
I/test (19493): Adapter.Count = 12
