I have constructed a
startvalue from a list of items and I pass this startvalue through 3 screens
second screen I need to add (append) another item onto the startvalue list.
need to add (append to above list (startvalue)
Please can someone show me how to do this. Ive searched and looked all over the place
Use the add items to list block
You can find it in the List drawer
I tried that but where does it add it to and how can I extract the item later because there is no connector
To select an item from the list use the select list item block
where does it add it to
Well, if the
get start value is a list, it adds your text as list item
Also what about using Do it?
use Do it to debug your blocks, see also tip 4 here App Inventor: How to Learn | Pura Vida Apps
see also Live Development, Testing and Debugging
I just have seen your screenshot in the first post… you are using TinyDB… in this case there is no need to pass the values like this to the other screen, just get the values from TinyDB there
Let me suggest you to do some tutorials to learn the basics…
A very good way to learn App Inventor or Kodular is to read the free Inventor’s Manual here in the AI2 free online eBook
App Inventor 2 Book: Create Your Own Android Apps … 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 Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps
How to do a lot of basic things with App Inventor are described here: How do you...? .
Also do the tutorials
Tutorials for MIT App Inventor to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor
I guess what im asking is this
unlike this block
where you get to add item to a start value when movinG to another screen (essentially making the equivalent of a session variable) HOW can on just write values INTO A startvalue to pick up on AMY SCREEN
