Qr code scanner that scans custom qr code and generates text in a list

[Ciarakitten]

So then what would I replace the label block with if I just wanted to see the results on my list view I have on my screen?

set ListView1.Elements to Bus_list might work.

While you are wondering, you might learn some basics about App Inventor coding. Especially Programming Lists of Data

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 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...? .

For my version of the app, the blocks would do the scanning and stuff, but the data then wouldn’t show up on the screen unless I use a label, which I don’t want to use because I want the item to be added to the list instead of on a separate label.

But, when I hit my “add bus button” on my screen, it adds what text was supposed to be there like this image below

Why so difficult ?

Hello, I'm trying to create a QR like yours and it's telling me that this API has been discontinued. Am I doing something wrong?

[TIMAI2]

It still works

It seems that Google Chart QR code API, which has been deprecated before, indeed doesn't work anymore and is returning 404 Not Found. As an alternative, I found QuickChart and use it in my projects now:

Your example would translate to:
https://quickchart.io/qr?size=200&text=yourdatahere

Heads Up: Google's QR code Infographic now shut down

QR Code Infographics For what has been a reliable online qr code generator for years has finally been shut down, having been deprecated in 2012! If you try to use it you will get a 502 error. Here is a short listing of some alternatives: https://api.qrserver.com/v1/create-qr-code/?size=70x70&data=ExampleText https://quickchart.io/qr?ecLevel=L&text=ExampleText https://qrcode.tec-it.com/API/QRCode?data=ExampleText Visit their api pages for instructions on more detailed use...
