Question

         Uri selectedImage = outputFileUri;
                     InputStream imageStream =getContentResolver().openInputStream(selectedImage);
                     try
                     {
                         BitmapFactory.Options bounds = new BitmapFactory.Options();
                         bounds.inJustDecodeBounds=true;                                                      BitmapFactory.decodeFile(Common.getRealPathFromURI(selectedImage, AddStoreActivity.this), bounds);
                         BitmapFactory.Options opts = new BitmapFactory.Options();
                         Bitmap bm = BitmapFactory.decodeFile(Common.getRealPathFromURI(selectedImage, AddStoreActivity.this), opts);
                         ExifInterface exif = new ExifInterface(Common.getRealPathFromURI(selectedImage, AddStoreActivity.this));
                         String orientString = exif.getAttribute(ExifInterface.TAG_ORIENTATION);
                         int orientation = orientString != null ? Integer.parseInt(orientString) :  ExifInterface.ORIENTATION_NORMAL;   
                         int rotationAngle = 0;
                         if (orientation == ExifInterface.ORIENTATION_ROTATE_90) rotationAngle = 90;
                         if (orientation == ExifInterface.ORIENTATION_ROTATE_180) rotationAngle = 180;
                         if (orientation == ExifInterface.ORIENTATION_ROTATE_270) rotationAngle = 270;
                         Matrix matrix = new Matrix();
                         matrix.setRotate(rotationAngle, (float) bm.getWidth() / 2, (float) bm.getHeight() / 2);
                         Bitmap rotatedBitmap = Bitmap.createBitmap(bm, 0, 0, bounds.outWidth, bounds.outHeight, matrix, true);
                         bitmap2 = rotatedBitmap;//BitmapFactory.decodeStream(imageStream);
                     }
                     catch(Exception ef)
                     {
                         bitmap2 = BitmapFactory.decodeStream(imageStream);
                     }

非常简单，在我的Android应用程序中，我打开相机..并以纵向模式拍照。我把图片重新旋转了。我怎么能解决这个问题？我所做的上述工作没有任何影响。

尝试替换此代码

matrix.postRotate(rotationAngle);
Bitmap rotatedBitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true);

用这个

(\b(serial|sheet))+(\s(number|code|no))+?\b

以纵向模式拍摄的照片会旋转
