You could try this extension:

[Discontinued] ListAddon Extension

[ListAddon] ListAddon Extension This extension allows for doing more things with App Inventor Lists. I made this extension with Kodular IDE. Current version: 1 Release date: 2019-04-21T21:00:00Z (UTC) Required permissions: none Min API required: N/A I decided the build this extension because I saw we can actually do more things with YailList (a Java object which used in App Inventor for lists.) So I created additional blocks for the built-in list blocks. Blocks [image] …

Bubble sort list without an extension (numbers/strings)

Hi guys! Just share a way to arrange a list without an extension. I found this link from this post: This is using the method of bubble sorting (Bubble sort - Wikipedia). Here is a gif from WIKI explaining how it works (sped up for better view) [Bubble sort] Let’s get started. Blocks you’ll need: Three global variables [Global block] Procedure block with three input [Bubble sorting blocks] Explanation: We need a procedure block with three input and return result [1] listToBeSor…

Btw, seems that your list is already sorted

[AryanGupta]

i already try this extension. Same Result.

[AryanGupta]

can we do it with for loop

[Mohamed_Tamer]

@AryanGupta

Same Result.

Seems that your list is already sorted 1-10-100-102-103,etc…I guess that is the right ascending order .

[AryanGupta]

sorry , i have value from 1 to 120.

[Mohamed_Tamer]

@AryanGupta

but there is no negative value.

Maybe you can show your whole list ? Do you have negitave values in your list.

[AryanGupta]

it showing 1-10 where is 2,3,4,5,6…

[AryanGupta]

Do It Result: ((1 10 100 101 102 103 104 105 106 107 108 109 11 110 111 112 113 114 115 116 117 118 119 12 120 13 14 15 16 17 18 19 2 20 21 22 23 24 25 26 27 28 29 3 30 31 32 33 34 35 36 37 38 39 4 40 41 42 43 44 45 46 47 48 49 5 50 51 52 53 54 55 56 57 58 59 6 60 61 62 63 64 65 66 67 68 69 7 70 71 72 73 74 75 76 77 78 79 8 80 81 82 83 84 85 86 87 88 89 9 90 91 92 93 94 95 96 97 98 99))

They are in non-numerical order.
All starting with 1 first …
All starting with 2 …
All starting with 3…

Sort List Numerically

I would like to sort a list of numbers to: (1,2,3,4,5,6,7,9,10,11,12,13,14,15,16,17,18,19,20) I tried ListUtils but it only sort by alphabet. [image] This is a sample. I have a huge list of numbers. Suggest me the best way to approach or maybe @Hossein add an option to the sort order.

The solution was what @Mohamed_Tamer suggested.

[Mohamed_Tamer]

@Rogerio_Rios

They are in non-numerical order.

Yes,It seems that ListUtils extension doesn’t sort vales in numerical order ( just in alphabetical order ) :

However:

[The_K_Studio (Karan M.)]

Try to make your list like this :
001, 002, 003…010, 011, 012…099, 100, 101

may be this works.

EDIT: Not working

It is working , just use a global variable

EDIT: Not working

i guess it’s about using text blocks ( Strigns ) instead of math blocks ( Integers ) :

probably because leading zeros are getting automatically removed, when using math blocks, but not with strings:

[Rogerio_Rios (Professional Support)]

Every number 0 to the left … is ignored
In the string 0 on the left … It is valid

In Sort list blocks the numbers are being treated as strings.
In BubbleSort blocks the numbers are being treated as numbers.
