Android Question Randomize the list

[Programing Center]

Hi, i have a List and i want to Randomize my List
For example my List content is :

    Dim listview As ListView
Dim list As List
list.Initialize
list.Add("Banana")
list.Add("home")
list.Add("car")
list.Add("cat")
list.Add("B4a")

For i = 0 To list.Size -1
    listview.AddSingleLine(list.Get(i))
Next

I want to randomly move items from my list
Is there any code?

I want to randomly move items from my list

If you mean that you want to select items from the list in random order then use something like this ...

Private Sub getRandomItem(input As List) As String
    If (input.Size < 1) Then Return ""
    Dim i As Int = Rnd(0, input.Size)
    Dim selection As String = input.Get(i)
    input.RemoveAt(i)
    Return selection
End Sub

The list will be progressively destroyed, so use a copy of your real list.

Learn the code. Should be trivial to make it work with a list.

Tip: never use ListView. Only xCLV.
