Android拍照得到的照片旋转了90度

解决办法：

int degree = ImageUtil.readPictureDegree(imageUri.getPath());Bitmap bmpOk = ImageUtil.rotateToDegrees(bmp, degree);

/** * 图片旋转 * @param tmpBitmap * @param degrees * @return */public static Bitmap rotateToDegrees(Bitmap tmpBitmap, float degrees) {    Matrix matrix = new Matrix();    matrix.reset();    matrix.setRotate(degrees);    return tmpBitmap =            Bitmap.createBitmap(tmpBitmap, 0, 0, tmpBitmap.getWidth(), tmpBitmap.getHeight(), matrix,                    true);}/** * 读取照片exif信息中的旋转角度 * @param path 照片路径 * @return角度           */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;}

bmpOK就是我们需要的没有旋转过的照片了。
