int rotation = c.getInt(c.getColumnIndex(MediaStore.Images.ImageColumns.ORIENTATION)); if (rotation != 0) { Bitmap bitmap = BitmapFactory.decodeFile(path); imageBefore.setImageBitmap(bitmap); Matrix m = new Matrix(); m.setRotate(rotation); Bitmap transformed = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), m, true); return transformed; } 这个方法里的c是什么？

int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, -1); 用这个方法获取到orientation可以吗？
