Android Question List key sequence

[nibbo]

Hi All

I use a webservice to return JSON data which looks something like:

Data:[{"col1":"value1","col2":"value2","col3":"value3","col4","value4"}{…etc...}]

I store save the above to the list:

dim recordList = root.Get("Data")

I then iterate through the list using:

For i = 0 To recordList.Size - 1
    Dim m As Map = recordList.Get(i)
    For Each k As String In m.Keys
        Log(k)
    Next
Next

But the order of the keys does not match the order in the JSON, in the example I am running it returns col1, col4, col2 , col3. Is that just how it works or should it retain the correct sequence?
I am sure it was in the correct order when I first wrote and tested the code!

Thanks

In most cases the order of items in Maps is not important. The order is lost in the native JSON parser implementation.
If the order is important you need to use an array ([]) instead of a key/value object ({}).
