B4J Question Save tableview items to file

[kazem forghani]

Hello
I've saved this way tableview items:

Dim items As List = ListContent.Items
File.WriteList(File.GetFileParent(URL), File.GetName(URL), items)

The stored information is:

How can tableview all items saved in the file so that you can read them again and added tableview?
I also saw the error was: https://www.b4x.com/android/forum/threads/save-tableview-items-to-file.58121/
Thank you

Assuming that the items are strings or numbers (and not nodes) then you can use RandomAccessFile to create a binary file with the data:

raf.WriteB4XObject(items, 0)
Dim items As List = read.ReadB4XObject(items, 0)

You can create a CSV file with StringUtils library.

Not items in a file txt (written with Map) stored?
