Hey Gliders!

I have built a stock count app using Glide Apps that is designed to work on an Android-based barcode scanner. The current process requires the user to click into a text field and then scan the barcode. Once scanned, the barcode value appears in the text field, but the user must then click a button to record the stock count.

I have two questions:

1. Is it possible to automatically trigger an action as soon as the barcode value is populated in the text field, instead of requiring the user to click a button? I’ve noticed that the barcode scanner automatically sends a “return” signal after scanning.
2. If the above is not possible, can I restrict the text field to a single line or trim the input value to prevent extra spaces, which can cause issues with item lookup?

Hi there, I’m not sure regarding the action trigger based on just the text entry, but regarding the barcode scanner, most are configurable so that you can add/remove prefixes and suffixes, so you should be able to remove the return, in order to just capture the code.

Barcode scanners has an on scan action, so I assume you can write the value to a column, and then trigger the action you want using that “on scan” section.

Hi ThinhDinh

I believe this is only available for the in app barcode scanning feature that uses the camera of the phone. I don’t think it works with the barcode scanner module built into the Andriod device.
