Android Code Snippet Multi selection list with B4XPreferencesDialog

If you need lists with more than one choice, one beautiful solution is, to use the B4XPreferencesDialog.

Dim mapDaten As Map
    mapDaten.Initialize
    pref.Theme= pref.THEME_LIGHT
    pref.AddSeparator("title")
    pref.AddExplanationItem("", "?", "some explanation")

Dim rs As ResultSet = SQL1.ExecQuery2("SELECT * FROM Items WHERE ..., Array As String(...))
    Do While rs.NextRow
        iID = rs.GetInt("ID")
        sName = rs.GetString("Name")
        'mapDaten.Put(iID, False) 'only needed, if some of the items are allready aktive
        pref.AddBooleanItem(iID, sName)
    Loop
    rs.Close
   
    Wait For (pref.ShowDialog(mapDaten, "OK", "CANCEL")) Complete (Result As Int)
    If Result = xui.DialogResponse_Positive Then
        For Each key As String In mapDaten.Keys
            bAktiv = mapDaten.GetDefault(key, False)
            If bAktiv Then
                'handling the choosen items ...
            End If
        Next
    End If

Good solution!
Another option is to use B4XDialog + B4XListTemplate. It can be configured to support multiple selections.
