Hi all

i m get a json result like this

{"Success":true,"Sent":{"Has":false},"NotSent":{"Has":false,"Amount":4,"Thumbnails":[{"PhotoID":"43","Url":"http:\/\/www.lala.com\/lala\/\/Files\/Users\/18\/Thumbnails\/0378750001408127092f58cd017a3b80ef6d315192973ebf7a2.jpg"},{"PhotoID":"42","Url":"http:\/\/www.lala.com\/lala\/\/Files\/Users\/18\/Thumbnails\/0378750001408126725123518fd3f73a70c4c1c65de84c4981a.jpg"},{"PhotoID":"41","Url":"http:\/\/www.lala.com\/lala\/\/Files\/Users\/18\/Thumbnails\/0191250001408126603f58cd017a3b80ef6d315192973ebf7a2.jpg"},{"PhotoID":"40","Url":"http:\/\/www.lala.com\/lala\/\/Files\/Users\/18\/Thumbnails\/0035000001408125442123518fd3f73a70c4c1c65de84c4981a.jpg"}]}}

Ok the result is 4 images,
Amount = 4

i have 10 imagesview (img1, img2, img3, img4 etc...)

i mm trying to get the result with for each

                        Dim Thumbnails As List = NotSent.Get("Thumbnails") 
                        For Each colThumbnails As Map In Thumbnails
                        Dim Url As String = colThumbnails.Get("Url")
                        Log(Url)
                        Dim photoid As String = colThumbnails.Get("PhotoID")
                        Log(photoid)
                        Next

The result is

getlink1 only and load this on imageview1

getlink2 load this on imageview2

getlink3 load this on imageview3 etc...

i never know the result amount of links, can is 2 photos or 3 max 10 (1 - 10)

thx to all, i m trying to learn *-*

Hi Douglas,

have a look at this Erel's tutorial here.
A List instead of an array could solve the unknown number of pictures returned problem.

Dim Thumbnails As List = NotSent.Get("Thumbnails")
Log(Thumbnails.Size)

Thumbnails is a LIST in this case. Learn how to use lists and you should be able to access any of the results.

Hi Douglas,

as far I can see, you print 4 times the same log: Thumbnails.Size -->(4 4 4 4) or Thumbnails.Get(0) --> (PhotoID93).
You should loop from min to max (0 to Size-1) to have your four distinct values.

[Douglas Farias]

can give one exemple? pls

I don't know how you set up the ImageView init code, but following Erel's code linked on post #2, you could do something like the following (it's more a concept scheme than a real code example):

Sub Globals
Dim ImageView1 As ImageView
Dim ImageView2 As ImageView
Dim ImageView3 As ImageView
...
Dim ImageView9 As ImageView
Dim ivs() As ImageView
End Sub

Sub Activity_Create(FirstTime AsBoolean)
Activity.LoadLayout("1")
ivs = Array As ImageView(ImageView1, ImageView2, ImageView3, ImageView4, _
ImageView5, ImageView6, ImageView7, ImageView8, ImageView9)
End Sub

' when you got your JSON result do something like:

Dim Thumbnails As List = NotSent.Get("Thumbnails")
Dim maxel,j as int
maxel = Thumbnails.Size
if maxel > 9 then maxel = 9 'discard eventual extra URLs
for j = 0 to maxel-1 do
   dim colThumbnails As Map
   colThumbnails = Thumbnails.Get(j)
    Dim Url AsString = colThumbnails.Get("Url")
    Log(Url)
    Dim photoid AsString = colThumbnails.Get("PhotoID")
    Log(photoid)
    assigntheimage(j,url,photoid)
next

sub assigntheimage(index as int, url as string, id as int)
' download the image
' ivs(index).tag = ID
'ivs(index).background = image
end sub

Consider the option of generating at runtime the imageviews you deserve.

Hi Douglas,

have a look at NJDUde's Grid library. It will easy your work a lot.
