Android 自定义 SurfaceView 方向无法从纵向旋转到横向
Android custom SurfaceView orientation can't rotate from portrait to landscape
我是一名新 android 应用工程师。我正在尝试制作一个 vulkan 渲染后端演示，它使用 SurfaceView 作为 android Java 代码上的视图。我也使用 GLSurfaceView 制作了 gles 渲染后端演示。在应用程序代码中，我使用 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) API 将 activity 从默认纵向设置为横向。但它在 SurfaceView 上不起作用，而在 GLSurfaceView 上起作用。
我用renderdoc抓取渲染结果，图片是横向布局的（和gles后端一样的布局）。我怀疑 activity 或 window 上的某些设置有问题，但无法找出根本原因。有人可以帮助解决问题吗？

在 AndroidManifest.xml 的 <activity> 标签中，添加行 android:screenOrientation="portrait".
参考https://www.geeksforgeeks.org/designing-the-landscape-and-portrait-mode-of-application-in-android/添加横向布局。布局文件将位于 res/layout-land/ 目录。布局 xml 文件与 res/layout 目录中的文件同名。该文件名将在 setContentView(R.layout.activity_layout_name) 中使用。 activity 的 landsacpe/portrait 布局选择在 AndroidManifest.xml 参数 android:screenOrientation="value" 中设置，作为实验值，而值要么是横向的，要么是纵向的。当我们在AndroidManifest.xml中选择纵向模式时，对应的activity会在res/layout目录下找到布局文件，并设置ContentView。选择景观时，它将在res/layout-land目录中找到布局文件。所以在res/layout和res/layout-land目录下，layout文件名应该是一样的，因为我们在activity里调用了setContentViewAPI，参数应该都适合res/layout 和 res/layout-land 目录中的文件。
我需要在横向布局中设置我的 activity，因此在 AndroidManifest.xml 对应的 activity 中，我设置 android:screenOrientation="横向"。
然后 Activity 代码将 setContentView 使用 res/layout-land 目录中的布局文件。在横向布局 xml 文件中，我有两个视图，一个是 GLSurfaceView，另一个是 VKSurfaceView。

在 AndroidManifest.xml 的 <activity> 标签中，添加行 android:screenOrientation="portrait".
参考https://www.geeksforgeeks.org/designing-the-landscape-and-portrait-mode-of-application-in-android/添加横向布局。布局文件将位于 res/layout-land/ 目录。布局 xml 文件与 res/layout 目录中的文件同名。该文件名将在 setContentView(R.layout.activity_layout_name) 中使用。 activity 的 landsacpe/portrait 布局选择在 AndroidManifest.xml 参数 android:screenOrientation="value" 中设置，作为实验值，而值要么是横向的，要么是纵向的。当我们在AndroidManifest.xml中选择纵向模式时，对应的activity会在res/layout目录下找到布局文件，并设置ContentView。选择景观时，它将在res/layout-land目录中找到布局文件。所以在res/layout和res/layout-land目录下，layout文件名应该是一样的，因为我们在activity里调用了setContentViewAPI，参数应该都适合res/layout 和 res/layout-land 目录中的文件。
我需要在横向布局中设置我的 activity，因此在 AndroidManifest.xml 对应的 activity 中，我设置 android:screenOrientation="横向"。
然后 Activity 代码将 setContentView 使用 res/layout-land 目录中的布局文件。在横向布局 xml 文件中，我有两个视图，一个是 GLSurfaceView，另一个是 VKSurfaceView。
