iOS Question Sort array

[Graeme Mitchell]

I am trying to sort the ListPart list. I tried listpart.sort(true) but it errors out. I checked the whole list to see if there were any anomalies but they are all numbers (2-4 digit)

Sub FillArray(Search As Int)

  
If Search < 99 Then
   partsList = su.LoadCSV(File.DirDocuments, "Database.txt", TAB)
   Dim MyArray (partsList.size,24) As String
   listpart.Initialize
       lastx = partsList.Size -2
   For i=0 To partsList.Size -2
       Dummy = partsList.Get (i)
       For j= 0 To 24
           MyArray (i,j)= Dummy(j)
       Next
       listpart.Add(cs.Initialize.Font(fnt).Append(MyArray(i,Search)).PopAll)
  
   Next
  
   SearchIndex = Search  
   PickerPart.SetItems(0,listpart)
   PickerPart.SetRowsHeight(40)
End If

End Sub

I tried listpart.sort(true) but it errors out

Where is the error message?

Where is the relevant code? I don't see any call to Sort.

 

[Graeme Mitchell]

The sort was just about the SearchIndex = Search line

listpart.sort(true)
SearchIndex = Search  
PickerPart.SetItems(0,listpart)
PickerPart.SetRowsHeight(40)

You cannot sort attributed strings or CSBuilders. Use B4XOrderedMap: https://www.b4x.com/android/forum/threads/b4x-b4xcollections-more-collections.101071

Add the regular strings as keys and the CSBuilders as values. Sort the keys and create a new list with the values.

 

[Graeme Mitchell]

So the command to create the OrderedMap is below but I am not sure how to implement this into my for next loop since I am only looking at the adding a numeric value which I assume is the value but what would be the key?

The first column in the partsList ir MyArray is a unique identifier but then I tried the code below to add that and I see the warning "Types do not match"

From website
Dim om As B4XOrderedMap = B4XCollections.CreateOrderedMap2(Array("a", "b", "c", "d"), Array(1, 2, 3, 4))

My Code
Dim om As B4XOrderedMap = B4XCollections.CreateOrderedMap2(MyArray(i,0),MyArray(i,search))

 

[Erel]

Something like:

Dim om As B4XOrderedMap = B4XCollections.CreateOrderedMap
 For i=0 To partsList.Size -2
       Dummy = partsList.Get (i)
       For j= 0 To 24
           MyArray (i,j)= Dummy(j)
       Next
       om.Put((MyArray(i,Search), cs.Initialize.Font(fnt).Append(MyArray(i,Search)).PopAll)
   Next
om.Keys.Sort(True)
   For Each s As String In om.Keys
       
listpart.Add(om.Get(s))
   Next

Thank you, that worked perfectly
