如何查看手机何时从竖屏变为横屏？ （在清单中强制使用纵向模式）
我对我的应用程序有特殊需求。我必须强制应用程序仅在纵向模式下工作，但我需要知道用户何时将手机移至横向模式。为什么？因为我正在显示带有纹理图像的 opengl 视图，并且当用户将手机位置更改为横向模式时，我必须旋转多边形而不重置活动。然后我必须在清单上强制使用纵向模式，因为我不希望再次调用我的 onCreate 方法。
请问，有人可以告诉我如何实现这一目标吗？
我知道如何旋转图像，我只需要知道用户何时将手机移动到横向位置，但强制显示纵向。
谢谢
I have a special need for my app. I must force the app to work only in portrait mode, but i need to know when the user has moved the phone to landscape mode. Why? because i am displaying a opengl view with a texture image, and when the user changues the phone position to landscape mode i must rotate the polygon without reseting the activity. Then i must force portrait mode on manifest, because i dont want that my onCreate method gets called again.
Please, can someone tell me how to achieve this?
I know how to rotate the image, i only need to know when the user has moved the phone to landscape position, but with portrait forced on manifest.
Thanks

我认为“强制纵向”是指在清单中添加
android:screenOrientation="portrait"。要知道方向何时更改，您需要做的就是将android:configChanges="keyboardHidden|orientation"添加到清单中的Activity中重写onConfigurationChanged()。这不是你需要的吗？这行不通吗？
By "forced portrait", I assume you mean adding
android:screenOrientation="portrait"in the manifest. All you need to do to know when orientation has changed is to also addandroid:configChanges="keyboardHidden|orientation"to the<activity>declaration in the manifest; and then overrideonConfigurationChanged()in yourActivity.Isn't this what you need? Doesn't this work?
阅读以下帖子；
如果您将其设置为传感器，然后检查您的活动，手机处于什么方向，您就可以采取相应的操作。
力方向
强制“纵向”方向模式
然后阅读此内容，特别是第一个答案 android:screenOrientation="传感器”
强制 Android Activity 始终使用横向模式
< a href="http://developer.android.com/reference/android/content/res/Configuration.html#orientation" rel="nofollow noreferrer">http://developer.android.com/reference/android/content/res/Configuration.html#orientation
Read the following posts;
If you set it to sensor and then check in your activity what orientation the phone is in you can take actions accordingly.
Force orientation
Force "portrait" orientation mode
Then read this, specially the first answer with android:screenOrientation="sensor"
Force an Android activity to always use landscape mode
