我试图模仿Android版YouTube应用的行为被点击视频播放器的全屏按钮时：

I am trying to mimic the behavior of the YouTube Android app when the "fullscreen" button is clicked in the video player:

如果设备是目前在肖像，马上旋转为横向（即使用户仍持纵向装置），并留在景观，直到用户旋转设备到横向，然后旋转回纵向如果设备目前在景观，马上旋转为纵向（即使用户仍持纵向装置），并留在肖像，直到用户旋转设备肖像，然后转回到风景线。在任何时间，允许用户手动旋转他们的设备到所需方向。

看来，如果我强迫旋转到横向或纵向使用：

It seems that if I force the rotation to landscape or portrait using:

getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

或

getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

...我立即失去检测传感器定位变化的能力（即当用户在景观，他们要手动旋转装置回人像）。

... I immediately lose the ability to detect sensor orientation changes (i.e. once the user is in landscape, and they want to manually rotate the device back to portrait).

如果我更改请求的方向在onConfigurationChanged未指定或传感器，定向简单翻转到横向/纵向（无论我从上面的要求），然后弹回匹配设备如何保持方向。

If I change the requested orientation to unspecified or sensor in onConfigurationChanged, the orientation briefly flips to landscape/portrait (whatever I requested from above) and then snaps back to the orientation that matches how the device is held.

这是如何实现以上？我的目标有什么想法

Any thoughts on how to achieve my goals above?

推荐答案

我有excact同样的问题。我最终什么了，用一个OrientationListener检测，当用户实际上倾斜手机横向的，然后设置定向SCREEN_ORIENTATION_SENSOR。

I had the excact same problem. What I ended up with was using an OrientationListener to detect when the user had actually tilted the phone to landscape and then setting the orientation to SCREEN_ORIENTATION_SENSOR.

OrientationEventListener orientationEventListener = 
new OrientationEventListener(getActivity()) {
    @Override
    public void onOrientationChanged(int orientation) {
        int epsilon = 10;
        int leftLandscape = 90;
        int rightLandscape = 270;
        if(epsilonCheck(orientation, leftLandscape, epsilon) ||
           epsilonCheck(orientation, rightLandscape, epsilon)){
                getMainActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
            }
        }

        private boolean epsilonCheck(int a, int b, int epsilon) {
            return a > b - epsilon && a < b + epsilon;
        }
    };
    orientationEventListener.enable();

您还需要添加检查画像，因为你需要描述在你原来的职位。

You would also need to add checks for portrait , because you described needing that in your original post.
