BarcodeScanner

Inheritance: java.lang.Object

public class BarcodeScanner

BarcodeScanner contains the functionality related to barcode recognition from android device camera.

This sample shows how to use BarcodeScanner.
 
 // BarcodeScanner should be initialized in custom Activity in onCreate method,
 because BarcodeScanner must to initialize BarcodeScannerActivity in application
 BarcodeScanner scanner = new BarcodeScanner(getActivity());
 // Sets OnScanFinishedHandler that takes custom implementation of OnScannerRecognitionFinishedListener.
 // This OnScanFinishedHandler will be called after return from BarcodeScannerActivity
 scanner.setOnScanFinishedHandler(recognitionHandler -> {
                     AlertDialog.Builder dialog = new AlertDialog.Builder(requireContext());
                     dialog.setMessage(((ClientResultsListener)recognitionHandler).resultString);
                     dialog.create().show();
                 });
 // Initialize custom implementation of OnScannerRecognitionFinishedListener
 ClientResultsListener listener = new ClientResultsListener();
 // Launch BarcodeScannerActivity
 scanner.launchBarcodeScanner(listener);

 // Custom implementation of OnScannerRecognitionFinishedListener that process barcode recognition result
 on BarcodeScannerActivity side
 private class CustomResultsListener implements OnScannerRecognitionFinishedListener
 {
     public String resultString;

     public ClientResultsListener() {}

     protected ClientResultsListener(Parcel in) {
         resultString = in.readString();
     }
