Change items in a listview

[hackhack]

Say you add 10 lines to a listview, can you change the text of say line 5 later? Or do you have to remove everything and repopulate it? (Won't that flash?)

You will need to remove all items after item 5 and then add them again. You can use a ScrollView instead which is easier to work with when working with short-medium sized lists.

A scrollview is like a panel except it can scroll around?

But that means I have to align individual items visually instead of just adding them?

Klaus has collected several examples of using ScrollView instead of ListView: http://www.b4x.com/forum/basic4andr...23-scrollview-examples-summary.html#post47137

Which would be handy if I knew that that was what i was supposed to use. But since I don't know what it does, I'm not going to read about it now...

As I wrote above, if your list is not very long then ScrollView is easier to work with and is easier to customize (when using ScrollView to show a list).

Its just when i asked "A scrollview is like a panel except it can scroll around?" I was hoping for a "yes" or "no".

I glanced at Klauses page, and some of that looks very nice.

ScrollView is a view that contains other views and allows the user to vertically scroll those views.

It's like a small window that you can move around to see something much bigger underneath.
Think like looking at some document paper but through a small square.
The square hole never moves, but you can move the document behind it with your finger.

ScrollView allows for vertical scrolling, it holds a panel, the panel holds the content.
