Question

I use Zxing to scan a bar code in Android

        Button button = (Button) this.findViewById(R.id.scan);
    button.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            IntentIntegrator.initiateScan(AntennaShow.this);
        }
    });

When I touch the button,I see a popup menu,which has Zxing and other bar-code-scan apps I installed before
Question:
How can I touch the button then automatically run the Zxing because 1,I need to use the Zxing to retrieve information I scanned 2,that can be troublesome for users to choose the apt app–Zxing

Answer 1

The easiest thing to do is to use the IntentIntegrator class supplied with the project. See http://code.google.com/p/zxing/wiki/ScanningViaIntent

It will handle restricting to the Barcode Scanner or Barcode Scanner+ packages by default.
