Android Question [CustomListView] Save position on screen

[m643]

Hello all,

I'm using the customListView class to show many items in the list. Everytime when I open an other activity and come back to the main activity, the customlistview loads again and the position on the screen is gone. Is it possible to save this position, so the user don't have to scroll again?

I checked the statemanager module, but I don't get this working for the customlistview. Can the statemanager do this job for me?

Thank you

You might be filling the list in Activity_Resume Sub .

It should do .. Add these subs to CustomListView class

Public Sub GetScrollPosition As Int       'get current scroll position
   Return sv.ScrollPosition
End Sub

Public Sub ScrollToPosition(Position As Int)     'immediately scroll to new position
   sv.ScrollToNow(Position) 
   'DoEvents  should not be neccessary ....
End Sub

Then when you leave main activity run below code ... and store this in Global Var or StateManager.

 iScrollPos  = CLV1.GetScrollPosition

When you return to main activity reset the scroll position with ...

CLV1.ScrollToPosition(iScrollPos)
