Android Question Sort a List of Maps by key value of the maps

[smercan]

I have a list filled with same type of maps.
Need to sort list by the any key value of maps.

I was trying to write a function for this and this sample code is working but I'am curious about that is there another way more simple or fast?

public Sub SortMapListByKeyValue(mapList As List, keyName As String, ascending As Boolean) As List
  
    Dim keyValList As List
    keyValList.Initialize
  
    For Each m As Map In mapList
        keyValList.Add(m.Get(keyName))
    Next
  
    keyValList.Sort(ascending)
  
    Dim newList As List
    newList.Initialize
  
    For i=0 To keyValList.Size-1
        For j=0 To mapList.Size-1
            Dim m As Map = mapList.Get(j)
            If m.Get(keyName)=keyValList.Get(i) Then
                newList.Add(m)
                mapList.RemoveAt(j)
                Exit
            End If
        Next
    Next
  
    Return newList
End Sub

How many keys in each map?

 

[smercan]

Count of map keys is not important I thought, the important thing that all maps must have the same parameter key

 

[stevel05]

No, but if there aren't too many you could use a Type and the SortType function of list.

 

[smercan]

You are right. I get a json list from httpJob. My laziness came first before to write a Type, convert all of them into new list and finally sort

You should use List.SortType (especially if the number of items is large).

I am interested in this; I'll use a loop for the each map of list item to convert to a user-defined type, and I'll sort the resulting list. Will not it be longer than the direct sorting maps?

Will not it be longer than the direct sorting maps?

No. Because your code goes over the list once for each item.

You can also remove the map at all and use a custom type. It will be easier.

Thank you so much..
