The InputList function in B4A is deprecated.
The B4XDialog (XUI Views library) with a B4XListTemplate (mentioned by 
@zed ) is a good alternative.
Some sample code:
	
	
	
	
	
	
	
	
	
		Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Public keuzedialog As B4XDialog
End Sub
Public Sub Initialize
    B4XPages.GetManager.LogEvents = True
End Sub
Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
End Sub
Private Sub Button1_Click
    keuzedialog.Initialize(Root)
    keuzedialog.PutAtTop = True
    keuzedialog.BackgroundColor = Colors.White
    Dim width As Int = GetDeviceLayoutValues.Width - 10dip
    Dim height As Int = GetDeviceLayoutValues.Height - 100dip
    Dim keuzelst As List
    keuzelst.Initialize
    keuzelst.Add("id1 - een heel lange tekst voor de eerste keuze die normaal gezien niet op 1 regel kan.")
    keuzelst.Add("id2 - een korte tekst")
    keuzelst.Add("id3 - een redelijk korte naam")
    Dim listtpl As B4XListTemplate
    listtpl.Initialize
    listtpl.Resize(width,height)
    listtpl.Options = keuzelst
    listtpl.CustomListView1.AsView.SetLayoutAnimated(0, 0dip, 0dip, width - 10dip, height)
    listtpl.CustomListView1.sv.SetLayoutAnimated(0, 0dip, 0dip, width - 10dip, height)
    listtpl.CustomListView1.DefaultTextBackgroundColor = xui.Color_White
    listtpl.CustomListView1.DefaultTextColor = xui.Color_Black
    keuzedialog.ButtonsHeight = 50dip        ' set to 1dip to force the user to select
    Wait For (keuzedialog.ShowTemplate(listtpl, "", "", "Cancel")) Complete (Result As Int)
    If Result = xui.DialogResponse_Positive Then
        xui.MsgboxAsync(listtpl.SelectedItem,"Selected item")
    End If
End Sub

But as you can see the first line is still longer than one line. The CustomListView from the template uses text items.
Another way to use a list is to use a B4XDialog with a custom layout.
	
	
	
	
	
	
	
	
	
		Private Sub Button1_Click
    keuzedialog.Initialize(Root)
    keuzedialog.PutAtTop = True
    keuzedialog.BackgroundColor = Colors.White
    Dim width As Int = GetDeviceLayoutValues.Width - 10dip
    Dim height As Int = GetDeviceLayoutValues.Height - 100dip
    Dim keuzelst As List
    keuzelst.Initialize
    keuzelst.Add("id1 - een heel lange tekst voor de eerste keuze die normaal gezien niet op 1 regel kan.")
    keuzelst.Add("id2 - een korte tekst")
    keuzelst.Add("id3 - een redelijk korte naam")  
    Dim pnl As B4XView = xui.CreatePanel("")
    pnl.SetLayoutAnimated(0dip, 0dip, 0dip,width - 10dip, height)
    pnl.LoadLayout("keuzedialog_layout")
    fill_clv1
    Dim rsub1 As ResumableSub =  keuzedialog.ShowCustom(pnl, "OK", "", "")
    Wait For (rsub1) Complete (Result As Int)
    If Result = xui.dialogResponse_Positive Then
        '
    End If
End Sub
Private Sub fill_clv1
    For i = 0 To keuze.Length -1
        Dim pnl As Panel = clv1_item(keuze(i))
        clv1.Add(pnl,i)
    Next
End Sub
Private Sub clv1_item(naam As String) As Panel
    Dim p As B4XView = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0dip, 0dip, clv1.AsView.Width,40dip)
    p.LoadLayout("clv1item_layout")
    lblnaam.Text = naam
    Return p
End Sub
Private Sub clv1_ItemClick (Index As Int, Value As Object)
    Log(clv1.GetValue(Index))
    clv1.GetPanel(Index).GetView(0).Color = xui.Color_Green
End Sub

In the custom layout (clv1item_layout) the lblnaam label Single Line property is checked. This causes the text to be truncated.
You can also use a B4XComboBox that also has a Single Line property you can check.

Or you can use a Spinner.

To answer your question: i don't think it is possible to set the items from an InputList to a single line (no wrapping).
