Knowing that Selection Returns the text in the ListView at the position of SelectionIndex.

and that the most recent item in the ListView is the first item (the most recent item in your ListView, depending on how you code and enter your messages in the list that populates the ListView ** ) might** allow you to do what you want. What have you tried?

• ListView

Here are some resources to help you learn to use the AI2 tools. A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.

There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles

How to do a lot of basic things with App Inventor are described here: http://www.appinventor.org/content/howDoYou/eventHandling .

First, get this clipboard extension from Pura Vida Apps to copy the text.

Then add these blocks:

Sounds like you are putting all the messages into one element of the listview

[SteveJG]

You do not need to copy the last item in your ListView using an extension.

Try this instead to copy to a Label (or any other component that accepts text)

Could you share an .aia of your project? There could be an issue when the user submits his message or when loading the message list.

[Md_Mamun]

Yes

where the elements come from? a list? then use the native block of List.

[Spicy_Topics]

why don't you use, select list item list (source list) index (length of the source list).. ?

[Md_Mamun]

Plese give me the extension

[Md_Mamun]

That is edited

@Md_Mamun

give me the extension

sorry, there is no extension to give you the last element of a list, this is the correct answer to get what you need

@Spicy_Topics

select list item list (source list) index (length of the source list)

and learn to work with lists

@Md_Mamun

give me the extension

Actually it makes no sense so. since it can be achieved by simple default block, there is no need of extension for that . Please refer the @Taifun reply to understand better the lists

[busybird15]

In your function to add the message to the list, do you use "append value to list" block? Agagin, could you share an .aia of your project? In the project, click Projects > Export selected project (.aia) to your computer. You can then use Google Drive, Dropbox, OneDrive, or Internxt Send to get a URL to paste here.
