我使用的摄像头，显示preVIEW只（不拍照或录制视频）。

I'm using the camera to show preview only (not to take pictures or record videos).

该应用程序始终处于纵向模式（风景模式被禁用）。 相机preVIEW总是旋转90度逆时针，我不能改变它 （既不setDisplayOrientation也不符合P.SET（方向，肖像）和P.SET（旋转，90））。

The app is always in portrait mode (landscape mode is disabled). The camera preview is always rotated 90 degrees ccw and I can't change it (neither with setDisplayOrientation nor with p.set("orientation", "portrait" ) and p.set("rotation", 90) ).

时的preVIEW始终旋转这样或者是设备相关？如果它总是像这样在纵向模式下，我可以将图像旋转之后。

Is the preview ALWAYS rotated like this or is it device dependent? If it was always like this in portrait mode, I could just rotate the image afterwards.

或者是有没有办法正确设置相机？我读了很多线程关于这一点，但没有答案为我工作（GALAXY S2，Android的V2.3）

Or is there a way to set up the camera correctly? I've read a lot of threads about this but no answer worked for me (Galaxy s2, Android v2.3)

推荐答案

要强制纵向：

设置安卓screenOrientation =画像在的Andr​​oidManifest.xml 并调用 camera.setDisplayOrientation（90）; 之前调用 camera.start preVIEW（）;

set android:screenOrientation="portrait" in your AndroidManifest.xml and call camera.setDisplayOrientation(90); before calling camera.startPreview();

我还没有在GS2测试，但它的作品每一个电话我已经测试上。

I have not tested on the GS2 but it works on every phone I have tested on.

注：setDisplayOrientation中添加了API 8级

Note: setDisplayOrientation was added in API Level 8
