I want to append data in the list view where user data will be stored and showed in the listview.
To change the ListView you need to update the List that populates the ListView.
Here is Sajal's List tutorial List Blocks On App Inventor | Imagnity
To store the data you need to save the List to a TinyDB if the data is only to be stored on the Android or you can use FirebaseDB, CloudDB, a spreadsheet used like a database or to save the data.
Hi everyone
i want user to enter some info then i want to add it to a listview and when the screen intialize put that infos the user enterd Before this time so how can i do it?
and delete options when the user select something from list how?
- you might save the original List with a name like originalList before you enter the additional information. If you want to compare the new information with the original information you will have to post both the old and new lists.
See how you delete in this example

I didn't understood how to add items
My question is How cam the user add some info's like phone number, name and image
and save it in a Tiny DB and show it to a list view for ever to user and this page for delete option i can't open it
This is the code for get the info's and put it in a listview
and this is for adding items to list
Here's a sample app showing how a ListView is only for viewing, and not the primary storage area for your data:
