Dim lstCodes As ListView
lstCodes.Initialize("ListView")
lstCodes.AddTwoLinesAndBitmap2("...
lstCodes.AddTwoLinesAndBitmap2("...

From the activity module

Sub Activity_Create(FirstTime As Boolean)
Activity.LoadLayout("layout")
Activity.AddView(mdlSubs.populateList(), 0dip, 0dip, 100dip, 100dip) ' java.lang.NullPointerException
...
End Sub

Click is not working on the Listitem Listview in activity module.

Sub lstCodes_ItemClick (Position As Int, Value As Object)
Log(Value)
End Sub

Change
lstCodes.Initialize("ListView")
to
lstCodes.Initialize("lstCodes")
