Question

I’m looking for some tutorial or sample how to use Zxing library within android’s Fragment.

UPDATE:

Using IntentIntegratorSupportV4 can I use only scanner if it installed on device or in my own app?
Because I want to use QR Scanner in my own app which has two tabs. In fist must be this scanner. How I can handle it?

Answer 1

This sample project demonstrates the use of IntentIntegrator, and you will find a compiled JAR containing that class in the project’s libs/ directory.

There are really only two steps:

1. Call (new IntentIntegrator(this)).initiateScan(); to bring up the scanner.

2. Implement onActivityResult() and use IntentIntegrator to help parse the results:

   public void onActivityResult(int request, int result, Intent i) {
       IntentResult scan=IntentIntegrator.parseActivityResult(request, result, i);
   
       if (scan!=null) {
           format.setText(scan.getFormatName());
           contents.setText(scan.getContents());
       }
   }
