Question

I am a new in developing area. I am trying to deal with the results after scanning a QR image. I am using the Zxing library. Right now only the content string can retrieve any data. But I want to scan a qr image to get the URL, telno and a string /text(which will be a numbered amount).
Could you pls show that with an example how can i get the data for telno and text both and store in strings. For now there is only one SCAN_RESULT which is stored in contents, but how can I get multiple results at a time from one QR code.

private void onQrActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub

    if (requestCode == 0) {
        if (resultCode == RESULT_OK) {
            Log.d(TAG, "onActivityResult " + resultCode);
            String contents = data.getStringExtra("SCAN_RESULT");
            String format = data.getStringExtra("SCAN_RESULT_FORMAT");
            paymentmsg.setText(contents);
            value_Qr = Float.parseFloat(contents);
            // Toast.makeText(this, format, Toast.LENGTH_SHORT).show();
            format = data.getStringExtra("SCAN_RESULT_FORMAT");
            // Handle successful scan
        }
        else if (resultCode == RESULT_CANCELED) {
            // Handle cancel
        }
    }
}

You have to parse the result. The result is in the content string. parse the content string.
If your qr code is contact

if(contents.startsWith("BEGIN:")){

                    String[] tokens = contents.split("\n");

                    for (int i = 0; i < tokens.length; i++)
                        {
                        System.out.println(" "+tokens[i]);

                        if(tokens[i].startsWith("BEGIN:"))
                        {
                            Type= tokens[i].substring(6);
                        }
                        else if(tokens[i].startsWith("N:"))
                        {
                             Name= tokens[i].substring(2);
                        }
                        else if(tokens[i].startsWith("ORG:"))
                        {
                             Org= tokens[i].substring(4);
                        }
                        else if(tokens[i].startsWith("TEL:"))
                        {
                             Tel= tokens[i].substring(4);
                        }
                        else if(tokens[i].startsWith("URL:"))
                        {
                             Url= tokens[i].substring(4);
                        }
                        else if(tokens[i].startsWith("EMAIL:"))
                        {
                             Email= tokens[i].substring(6);
                        }
                        else if(tokens[i].startsWith("ADR:"))
                        {
                              Adr= tokens[i].substring(4);
                        }
                        else if(tokens[i].startsWith("NOTE:"))
                        {
                              Note= tokens[i].substring(5);
                        }

                        }   

if your qr scannrd is url

else if(contents.startsWith("http://")||(contents.startsWith("www."))){

                    qr_url= contents;

if your qr scanned is location qr

else if(contents.startsWith("geo:")){

                    String delims = "[ , ?q= ]+";
                    String[] tokens = contents.split(delims);

                    for (int i = 0; i < tokens.length; i++)
                    {
                        System.out.println(" "+tokens[i]);
                        if(tokens[i].startsWith(" geo:"))
                        {
                              qr_latitude= tokens[i].substring(4);

                        }
                    }
                    qr_latitude= tokens[0].substring(4);
                    qr_longitude=tokens[1];
                    geo_place=tokens[2];

And so on you can parse the result. Its all about how you can parse a string.
