The "zxing Barcode" scanner works successfully in my application
https://github.com/journeyapps/zxing-android-embedded
I want to open a scan screen (i.e. Intent), on the same Activity in the center in a small window
How can I get this type of interface?

You can use Journey Library . You can use the scanner as a component, as an image or text. It is based on ZXing. =)
