Android:纵向模式下的相机预览方向 [英] Android: Camera preview orientation in portrait mode

问题描述

我使用相机仅显示预览(不拍照或录制视频).

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

应用始终处于纵向模式(横向模式已禁用).相机预览总是逆时针旋转 90 度，我无法更改它(无论是 setDisplayOrientation 还是 p.set("orientation", "portrait" ) 和 p.set("rotation", 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) ).

预览总是像这样旋转还是取决于设备?如果在纵向模式下总是这样，我可以在之后旋转图像.

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.

或者有没有办法正确设置相机?我已经阅读了很多关于此的主题，但没有任何答案对我有用(Galaxy s2，Android 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

强制纵向:

在您的 AndroidManifest.xml 中设置 android:screenOrientation="portrait" 并在调用 之前调用 camera.setDisplayOrientation(90);>camera.startPreview();

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

我没有在 GS2 上测试过，但它适用于我测试过的每部手机.

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

注意:在 API 级别 8
