    </LinearLayout>


</LinearLayout>



Step 3:


BarcodeActivity.java

public class BarcodeActivity extends AppCompatActivity implements ZXingScannerView.ResultHandler{

    private ZXingScannerView mScannerView;

    @Override    public void onCreate(Bundle state) {
        super.onCreate(state);
        mScannerView = new ZXingScannerView(this);   // Programmatically initialize the scanner view       
        setContentView(mScannerView);                // Set the scanner view as the content view    }

    @Override    public void onResume() {
        super.onResume();
        mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.  
        mScannerView.startCamera();          // Start camera on resume    }

    @Override    public void onPause() {
        super.onPause();
        mScannerView.stopCamera();           // Stop camera on pause    }

    @Override    public void handleResult(Result rawResult) {

        BarcodeQrcodeFragment.tx_scan.setText("Scan Result : "+rawResult.getText());
        onBackPressed();

    }
}


Step 4:


BarcodeQrcodeFragment .java

public class BarcodeQrcodeFragment extends Fragment{
    public static TextView tx_scan;
    Button bt_scan;
    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        final View view = inflater.inflate(R.layout.fragment_bar_qr_code, container, false);

        bt_scan=(Button)view.findViewById(R.id.buttonScan);
        tx_scan=(TextView)view.findViewById(R.id.text_scan);

        bt_scan.setOnClickListener(new View.OnClickListener() {
            @Override            public void onClick(View v) {
                Intent intent = new Intent(getActivity(),BarcodeActivity.class);
                startActivity(intent);
            }
        });
        return view;
    }
    }
