문제 설명
zxing이 브라우저에서 URL을 열도록 하거나 스캔 후 번호를 다이얼하는 방법 (How to make zxing open a URL in a browser or dial a number after scanning)
스캔 후 앱에서 수행하기를 원하는 것은 번호를 표시하는 대신 다이얼하는 것입니다.그래서 저는 Android 개발 및 zxing 라이브러리를 처음 접했습니다. zxing 라이브러리를 사용하여 독립 실행형 QR 스캐너 앱을 만들 수 있었지만 문제는 QR 코드를 스캔할 때 브라우저에서 URL을 열거나 QR 콘텐츠를 기반으로 다른 작업을 수행하기를 원한다는 것입니다. QR 코드의 문자열 내용을 표시하는 대신. 예를 들어, QR 코드의 문자열 내용이 URL "www.stackoverflow.com"인 경우 QR 코드의 문자열 내용을 표시하는 대신 앱에서 사이트로 이동하기를 원합니다.
이것은 내 CaptureActivity에 대한 코드입니다

방법 1:
You question is not very clear, you have to put some source code to explain your issue.
You could use this library: https://github.com/zxing/zxing/wiki/Scanning‑Via‑Intent
and in your activity:
private void launchScanBarcode(){
IntentIntegrator integrator = new IntentIntegrator(yourActivity);
integrator.initiateScan();
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (scanResult != null) {
// handle scan result with scanResult.getContents() or scanResult.getRawBytes()
}
// else continue with any other code you need in the method
...
}
