you mean String Array ?

try
B4X:
'Put the variable name instead of S
S(0) 'Display name 
S(1) 'Starred
S(2) 'Id
S(3) 'Notes
S(4) 'TimesContacted
.......

Klaus,

thank you for your answer


B4X:
Dim findincotacts As Contacts2
Dim Mystring As String
Mystring=findincotacts.FindByName("John",False,True,False)
Log(Mystring)

And in log message I get this:
(ArrayList) [DisplayName=John, Starred=false, Id=5, Notes=, TimesContacted=110, LastTimeContacted=1425121693778, Name=John]

How can I get value from this string. For example Id?
Thank you very much

FindByName returns List not String

try this code instead
B4X:
Dim findincotacts As Contacts2
Dim aList As List
aList.Initialize
aList=findincotacts.FindByName("John",False,True,False)
For i = 0 To aList.Size -1
    Log(aList.Get(i))
Next

KZero,

thank you for your answer.
I tryed your code, but lin Log message I get this result:
DisplayName=John, Starred=false, Id=5, Notes=, TimesContacted=110, LastTimeContacted=1425121693778, Name=John

but how can I get only value which I need, for example Id?
Dim readid as String
readid=value ID from aList

I am trying .Get(i) and .IndexOf(i) but nothing...

Please for help,
thank you very much

Hi,

try the code below:
B4X:
'Create a list which holds the requested arraylist. The arraylist is a map
Dim l As List : l.Initialize
'(ArrayList) [DisplayName=John, Starred=False, Id=5, Notes=, TimesContacted=110, LastTimeContacted=1425121693778, Name=John]
'Create the arraylist and add to the list
l.Add(CreateMap("DisplayName":"John", "Starred":False, "Id":5, "Notes":"", "TimesContacted":110, "LastTimeContacted":"1425121693778", "Name":"John"))
'Log the list which shows the same content as requested (ArrayList)...
Log(l)
'Example to Log all map entries Key and Value by getting the first entry of the list which is the map
Dim m As Map = l.Get(0)
For i = 0 To m.Size - 1
    Log(m.GetKeyAt(i) & " = " & m.GetValueAt(0))
Next
'
'Now get any key requested, like
'
'Get Name - which outputs John
Log("Name is " & m.Get("Name"))
'Get TimesContacted - which outputs 110
Log("TimesContacted is " & m.Get("TimesContacted"))

FindByName returns all matched contacts not always 1 contact
each item contains all the contact's data
the easiest way to split this data to use Regex

B4X:
Dim findincotacts As Contacts2
Dim aList As List
Dim ContactData() As String
aList=findincotacts.FindByName("John",False,True,False)
For i = 0 To aList.Size -1
    ContactData = Regex.Split(",",aList.Get(i))
    For j = 0 To ContactData.Length -1
        Log(ContactData(j))
    Next
Next

Just use the code Kzero gave you, then cut up the string at ",", remove leading spaces from the string pieces, cut each pieace at "=" and then you have the key and value.

Just look at the string handling functions, they have all the tools you need.
