主要通过获取EXIF信息进行设置:

public static int readPictureDegree(String path) {        int degree  = 0;        try {                ExifInterface exifInterface = new ExifInterface(path);                int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);                switch (orientation) {                case ExifInterface.ORIENTATION_ROTATE_90:                        degree = 90;                        break;                case ExifInterface.ORIENTATION_ROTATE_180:                        degree = 180;                        break;                case ExifInterface.ORIENTATION_ROTATE_270:                        degree = 270;                        break;                }        } catch (IOException e) {                e.printStackTrace();        }        return degree;    }
