Android 自定義 SurfaceView 方向無法從縱向旋轉到橫向

Question

我是一名新的android應用工程師。 我正在嘗試制作一個 vulkan 渲染后端演示，它使用 SurfaceView 作為 android Java 代碼上的視圖。 我也使用 GLSurfaceView 制作了 gles 渲染后端演示。 在應用程序代碼中，我使用 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) API 將活動從默認縱向設置為橫向。 但是它在 GLSurfaceView 上工作時在 SurfaceView 上不起作用。

我使用 renderdoc 捕獲渲染結果，圖像是橫向布局（與 gles 后端相同的布局）。 我懷疑活動或 window 的某些設置有問題，但無法找出根本原因。 有人可以幫助解決問題嗎？

這里是 Java 源代碼。

Answer 1

在 AndroidManifest.xml 的標簽中，添加行 android:screenOrientation="portrait"

謝謝

Answer 2

參考https://www.geeksforgeeks.org/designing-the-landscape-and-portrait-mode-of-application-in-android/添加橫向布局。 布局文件將位於 res/layout-land/ 目錄。 布局 xml 文件與 res/layout 目錄中的文件同名。 此文件名將用於 setContentView(R.layout.activity_layout_name)。 Activity 的橫向/縱向布局的選擇在 AndroidManifest.xml 參數 android:screenOrientation="value" 中設置，而值是橫向或縱向。 當我們在AndroidManifest.xml中選擇豎屏模式時，對應的activity會在res/layout目錄下找到layout文件並setContentView。 選擇景觀時，它將在Res/Layout-Land目錄中找到布局文件。 這就是為什么 res/layout 和 res/layout-land 目錄下，layout文件名應該是一樣的，因為我們在activity中調用setContentView API，這個參數應該同時適合res/layout和res/layout-中的文件土地目錄。

我需要在橫向布局中設置我的活動，所以在 AndroidManifest.xml 對應的活動中，我設置了 android:screenOrientation="landscape"。

然后 Activity 代碼將 setContentView 使用 res/layout-land 目錄中的布局文件。 在橫向布局 xml 文件中，我有兩個 View，一個是 GLSurfaceView，另一個是 VKSurfaceView。
