Android:在 setRequestedOrientation 后自动旋转不起作用 [英] Android: Auto Rotate not working after setRequestedOrientation

问题描述

我有一个视频播放器，其中有两个功能:

I have a video player in which I have two features:

1. 如果自动旋转被禁用，并且当用户点击全屏按钮时，我会使用 setRequestedOrientation() 强制 orientation 进入 landscape 视图ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE) 并在退出全屏时返回纵向视图.

1. If the auto-rotate is disabled and when the user clicks on fullscreen button I force the orientation to go in landscape view using setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE) and back to portrait view when fullscreen is exited.

我已覆盖 onConfigurationChanged 以检测用户启用自动旋转功能时方向的变化，并根据方向更改活动视图.

I have overridden the onConfigurationChanged to detect the change in orientation when the auto-rotate feature is enabled by user and change the activity view according to the orientation.

现在这个设置的问题是，如果用户启动活动并进入全屏，并且 setRequestedOrientation 被调用一次，稍后当 auto-rotate 启用时，活动不会收到方向更改并且 onConfigurationChanged 不会被调用.

Now the problem with this setup is that if user start the activity and goes in fullscreen and setRequestedOrientation get invoked once, later when auto-rotate is enabled, the activity doesn't receive the orientation changes and the onConfigurationChanged doesn't get called.

我在这里读到(https://stackoverflow.com/a/6109206/5167868)他们不会同时工作.

I read here (https://stackoverflow.com/a/6109206/5167868) that they wont work simultaneously.

我想知道是否有办法实现这两者，因为我看到像 MX Player 这样的播放器在他们的应用中执行此操作.

I would like to know if there a way of implementing both as I have seen players like MX Player do this in their app.

推荐答案

使用 setRequestedOrientation() 固定屏幕方向后，自动旋转功能将不起作用.所以为了让它工作，你可以做这样的事情:

After you fix the orientation of the screen by using setRequestedOrientation(), Auto Rotate feature won't work. So to make it work, you may do something like this:

使用以下方法设置方向后:setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE)

After you set your orientation using: setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE)

这样称呼:setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED)

这将使自动旋转再次工作！

This shall make the auto rotate to work again!
