Android 용 ZBAR을 사용하여 QR 코드 스캔 작업을 트리거하는 방법은 무엇입니까?

Question

나는 ZBar 안드로이드 라이브러리를 사용하여 QR 코드를 스캔하고 있습니다. 지금까지 코드가 스캔되고 스캔 결과가 textView에 표시됩니다. qr 코드를 스캔하고 이에 따라 조치를 실행하는 다른 앱처럼 코드가 스캔 될 때 작업을 트리거하려고합니다. 여기

public class CameraTestActivity extends Activity 
{ 
    private Camera mCamera; 
    private CameraPreview mPreview; 
    private Handler autoFocusHandler; 

    TextView scanText; 
    Button scanButton; 

    ImageScanner scanner; 

    private boolean barcodeScanned = false; 
    private boolean previewing = true; 

    static { 
     System.loadLibrary("iconv"); 
    } 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     setContentView(R.layout.main); 

     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

     autoFocusHandler = new Handler(); 
     mCamera = getCameraInstance(); 

     /* Instance bar code scanner */ 

     scanner = new ImageScanner(); 
     scanner.setConfig(0, Config.X_DENSITY, 3); 
     scanner.setConfig(0, Config.Y_DENSITY, 3); 

     mPreview = new CameraPreview(this, mCamera, previewCb, autoFocusCB); 
     FrameLayout preview = (FrameLayout)findViewById(R.id.cameraPreview); 
     preview.addView(mPreview); 

     scanText = (TextView)findViewById(R.id.scanText); 

     scanButton = (Button)findViewById(R.id.ScanButton); 

     scanButton.setOnClickListener(new OnClickListener() { 
       public void onClick(View v) { 
       if (barcodeScanned) { 
        barcodeScanned = false; 
        scanText.setText("Scanning..."); 
        mCamera.setPreviewCallback(previewCb); 
        mCamera.startPreview(); 
        previewing = true; 
        mCamera.autoFocus(autoFocusCB); 
        } 
       } 
      }); 
    } 

    public void onPause() { 
     super.onPause(); 
     releaseCamera(); 
    } 

    /** A safe way to get an instance of the Camera object. */ 
    public static Camera getCameraInstance(){ 
     Camera c = null; 
     try { 
      c = Camera.open(); 
     } catch (Exception e){ 
     } 
     return c; 
    } 

    private void releaseCamera() { 
     if (mCamera != null) { 
      previewing = false; 
      mCamera.setPreviewCallback(null); 
      mCamera.release(); 
      mCamera = null; 
     } 
    } 

    private Runnable doAutoFocus = new Runnable() { 
      public void run() { 
       if (previewing) 
        mCamera.autoFocus(autoFocusCB); 
      } 
    }; 

    PreviewCallback previewCb = new PreviewCallback() { 
     public void onPreviewFrame(byte[] data, Camera camera) { 
      Camera.Parameters parameters = camera.getParameters(); 
      Size size = parameters.getPreviewSize(); 

      Image barcode = new Image(size.width, size.height, "Y800"); 
      barcode.setData(data); 

      int result = scanner.scanImage(barcode); 

      if (result != 0) { 
       previewing = false; 
       mCamera.setPreviewCallback(null); 
       mCamera.stopPreview(); 

       SymbolSet syms = scanner.getResults(); 

       for (Symbol sym : syms) { 
        scanText.setText("barcode result " + sym.getData()); 
        barcodeScanned = true; 
       } 
      } 
     } 
    }; 

    // Mimic continuous auto-focusing 
    AutoFocusCallback autoFocusCB = new AutoFocusCallback() { 
      public void onAutoFocus(boolean success, Camera camera) { 
       autoFocusHandler.postDelayed(doAutoFocus, 1000); 
     } 
     }; 
    }

이 시도 내 구현, 난 zbar을 사용하고 성공적인 스캔에 경고 대화 트리거하기 위해이 코드를 사용했다 :

public void onActivityResult(int requestCode, int resultCode, Intent intent) { 
    if (requestCode == 0) { 
     if (resultCode == getActivity().RESULT_OK) { 
      // Handle successful scan 
      String contents = intent.getStringExtra("SCAN_RESULT"); 
      //contents has your scanned string 
      //you can trigger your action here 


     } else if (resultCode == getActivity().RESULT_CANCELED) { 
      // Handle cancel 
     } 
    } 
}
