如何才能让我的Andr​​oid应用程序是横向或纵向，但没有反方向？

How can make my android application to be Landscape or portrait but without the reverse directions?

含义，我想启用 SCREEN_ORIENTATION_PORTRAIT 和 SCREEN_ORIENTATION_LANDSCAPE ，但禁用 SCREEN_ORIENTATION_REVERSE_LANDSCAPE 和 SCREEN_ORIENTATION_REVERSE_PORTRAIT 。

Meaning that I want to enable SCREEN_ORIENTATION_PORTRAIT and SCREEN_ORIENTATION_LANDSCAPE but to disable SCREEN_ORIENTATION_REVERSE_LANDSCAPE and SCREEN_ORIENTATION_REVERSE_PORTRAIT.

感谢

我在我的相机应用了同样的问题/功能请求，并发现这篇文章：

I had the same problem/feature request in my camera app, and found this post:

android相机surfaceview方向

在changeRotation刚刚评 ORIENTATION_PORTRAIT_INVERTED 和 ORIENTATION_LANDSCAPE_INVERTED ，并创建一个方法 rotateViews（INT度）常规横向/纵向之间切换时旋转的所有图像（按钮），你的布局。

In changeRotation just comment ORIENTATION_PORTRAIT_INVERTED and ORIENTATION_LANDSCAPE_INVERTED, and create a method rotateViews(int degrees) to rotate all of the images(buttons) of your layout when switching between regular landscape/portrait.

此外，

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

比

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR | ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
