Изображение обратное: Android

Question

Я попытался захватить изображение, используя вид поверхности, и сохранил его в папке. Теперь, когда я просматриваю изображение в режиме просмотра изображений, изображение отображается в обратном порядке. Как я могу увидеть изображение без обращения вспять. Любые предложения, пожалуйста ..........

Это часть кода ..

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 


    getWindow().setFormat(PixelFormat.UNKNOWN); 
    surfaceView = (SurfaceView)findViewById(R.id.surfaceview); 
    surfaceHolder = surfaceView.getHolder(); 
    surfaceHolder.addCallback(this); 


    rawCallback = new PictureCallback() 
    { 
     public void onPictureTaken(byte[] data, Camera camera) 
     { 
      Log.d("Log", "onPictureTaken - raw"); 
     } 
    }; 

    shutterCallback = new ShutterCallback() 
    { 
     public void onShutter() { 
      Log.i("Log", "onShutter'd"); 
     } 
    }; 

    jpegCallback = new PictureCallback() 
    { 
     public void onPictureTaken(byte[] data, Camera camera) 
     { 

      Intent imageIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
      File imagesFolder = new File(Environment.getExternalStorageDirectory(), "Asw/Raw Image"); 
      imagesFolder.mkdirs(); 
      Date d = new Date(); 
      CharSequence s = DateFormat.format("MM-dd-yy hh-mm-ss", d.getTime()); 
      name = s.toString() + ".jpg"; 
      File output = new File(imagesFolder, name); 
      callname = "/sdcard/"Asw/RawImage/" + name; 

      Uri uriSavedImage = Uri.fromFile(output); 
      imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage); 

      OutputStream imageFileOS; 

      try { 
       imageFileOS = getContentResolver().openOutputStream(uriSavedImage); 

       ExifInterface exif = new ExifInterface(name); 
       int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 
         ExifInterface.ORIENTATION_NORMAL); 

       switch (orientation) { 
       case ExifInterface.ORIENTATION_ROTATE_270: 
        rotate = 270; 
        break; 
       case ExifInterface.ORIENTATION_ROTATE_180: 
        rotate = 180; 
        break; 
       case ExifInterface.ORIENTATION_ROTATE_90: 
        rotate = 90; 
        break; 
       } 
       // Log.v(Common.TAG, "Exif orientation: " + orientation); 
       Log.d("Fragment", "EXIF info for file " +name+ ": " + rotate); 

       imageFileOS.write(data); 
       imageFileOS.flush(); 
       imageFileOS.close(); 

       } 
      catch (FileNotFoundException e) 
       { 
       e.printStackTrace(); 
       } 
      catch (IOException e) 
      { 
       e.printStackTrace(); 
       Log.d("Fragment", "Could not get EXIF info for file " + name+ ": " + e); 
      } 
      finally 
      {} 
      Log.d("Log", "onPictureTaken - jpeg"); 


      Bitmap bitmap = BitmapFactory.decodeFile(callname); 

      imageView.setImageBitmap(bitmap);//Displaying raw Image

попробуйте этот код, Надеюсь, что это поможет вам.

int rotate = 0; 
       try { 
        getContentResolver().notifyChange(imageUri, null); 
        File imageFile = new File(imagePath); 
        ExifInterface exif = new ExifInterface(
          imageFile.getAbsolutePath()); 
        int orientation = exif.getAttributeInt(
          ExifInterface.TAG_ORIENTATION, 
          ExifInterface.ORIENTATION_NORMAL); 

        switch (orientation) { 
        case ExifInterface.ORIENTATION_ROTATE_270: 
         rotate = 270; 
         break; 
        case ExifInterface.ORIENTATION_ROTATE_180: 
         rotate = 180; 
         break; 
        case ExifInterface.ORIENTATION_ROTATE_90: 
         rotate = 90; 
         break; 
        } 
        Log.v("***TAG***", "Exif orientation: " + orientation); 
       } catch (Exception e) { 
        e.printStackTrace(); 
       }
