Use Barcode Scanner embeded in frame android

I want to create an app that scanned and get code from a qr-code barcodes.

In main layout I have a rectangle frame that show camera view [always app is open].

A textview is below of frame. enter image description here

When a qr-code put in frame code of barcode scanned and copied to textview.

How can I implement this idea?

How to customize barcode scanner library like zxing for that?

How to capture picture and get code of inside that?

Solution

This would require modifications to the zxing library. There is a third party project that added fragment support to zxing, you should check it out.
