我知道在某些设备中捕获的图像被旋转是正常的，但我遇到的问题是，当它们从小米设备捕获时，我无法获得这些图像的旋转值。

可能与这个问题有关

但我尝试了几种建议的解决方案，其中一些适用于我的索尼 Xperia 等其他设备，但没有一个适用于小米。

这些是我获取旋转值的一些尝试，但它们都返回 0 作为旋转值...

public int getRotation () {
    // using camera 2 methods to get orientation
    int orientation = 0;
    int orientation2 = getWindowManager().getDefaultDisplay().getOrientation();
    CameraManager manager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
    try {
        String cameraId = manager.getCameraIdList()[0];
        CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraId);
        orientation = characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
    }
    catch (Exception e){
        e.printStackTrace();
    }
    return orientation;
}

private int getImageOrientation(){
    final String[] imageColumns = { MediaStore.Images.Media._ID, MediaStore.Images.ImageColumns.ORIENTATION };
    final String imageOrderBy = MediaStore.Images.Media._ID+" DESC";
    Cursor cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            imageColumns, null, null, imageOrderBy);

    if(cursor.moveToFirst()){
        int orientation = cursor.getInt(cursor.getColumnIndex(MediaStore.Images.ImageColumns.ORIENTATION));
        cursor.close();
        return orientation;
    } else {
        return 0;
    }
}

private int getOrientationUsingExif (String photoPath) {
    ExifInterface ei = null;
    int orientationDegree = 0;
    try {
        ei = new ExifInterface(photoPath);
        int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION,
                ExifInterface.ORIENTATION_UNDEFINED);
        switch(orientation) {

            case ExifInterface.ORIENTATION_ROTATE_90:
                orientationDegree = 90;
                break;

            case ExifInterface.ORIENTATION_ROTATE_180:
                orientationDegree = 180;
                break;

            case ExifInterface.ORIENTATION_ROTATE_270:
                orientationDegree = 270;
                break;

            case ExifInterface.ORIENTATION_NORMAL:
            default:
                orientationDegree = 0;
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return orientationDegree;
}

任何帮助将不胜感激。
