Hi, I am using tabstripviewer from the excellent example.
Using the designer I created Page3 which holds Page3ListView1 as a listview
Everything works great,
Except when the data is updated I want to redo the loop with the new data or over-write the listview with the new data- getting rid of the old data and just showing the most recent data (which includes the old data plus new items)
What happens in the listview is that I can add things to end but not start over or reinitialize it?
Does not seem to do anything.
How do i re-start the listview as empty?
B4X:
Private TabStrip1 As TabStrip
Private Page3ListView1 As ListView
Private MasterList As List 'master list of data in file
Private DisplayList As List 'list in display format
B4X:
Activity.LoadLayout("Main")
TabStrip1.LoadLayout("Page1", "HOME")
Dim logo As Bitmap
logo = LoadBitmap(File.DirAssets, "logo.png")
Logo1.Bitmap=logo
TabStrip1.LoadLayout("Page2", "SETTNGS")
TabStrip1.LoadLayout("Page3", "VIEW DATA")
Activity.AddMenuItem("Jump to HOME", "mnu1")
Activity.AddMenuItem("Jump to SETTINGS", "mnu2")
Activity.AddMenuItem("Jump to VIEW DATA", "mnu3")Everything works great,
B4X:
for i = 1 to intenddata
Page3ListView1.AddSingleLine(strdata(i))
