问题描述
当我采取与机器人相机应用的图片，检测手机的方向，并相应地保存照片。所以，如果我把建筑物的照片，屋顶将在上行路上，我是否拿着手机在横向位置或肖像。
When I take a picture with Androids camera app, it detects the phone's orientation and saves the pic accordingly. So if i take a picture of a building, the roof will be on the topside, whether I hold the phone in landscape position or portrait.
然而，当我使用
意图imageCaptureIntent =新的意图（MediaStore.ACTION_IMAGE_CAPTURE）;
Intent imageCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
要获得照片时，相机应用程序不应对方向。 如果我拿着手机垂直（纵向），将得到的峰将被旋转，与所述建筑物的屋顶，以在屏幕的左侧。
to get a picture, the camera app doesn't react to orientation. If i hold the phone vertically (portrait), the resulting pic will be rotated, with said building's roof to the left of the screen.
我如何设置的意图，使相机将定位考虑？
How can I set the intent so that the camera will take orientation into account?
或者，我可以推断出以某种方式在什么方位事先知情同意拍摄，并随后将其旋转自己？
Or can I deduce in some way in what orientation the pic was taken and rotate it myself afterward?
或任何其他建议，将大大AP preciated。
Or any other suggestion will be greatly appreciated.

找到了答案。图像的EXIF具有取向的指标。为以防万一，EXIF可以被视为在Android中是这样的：
Found the answer. The exif of the image has an indicator of the orientation. Just in case, exif can be viewed in Android like this:
ExifInterface exif = new ExifInterface("filepath");
exif.getAttribute(ExifInterface.TAG_ORIENTATION);
