安卓 UnityPlayerActivity Action Bar

我正在构建一个包含Unity 3d交互式体验的Android应用程序。

我已将Unity项目导入Android Studio，但启动时活动是全屏的，不显示Android操作栏。

我该怎么做？

集成步骤

• 创建新的 Unity 项目。
• 从Unity导出“Google Android Project”。
• 将项目导入 Android Studio。

尝试的解决方案

• 更改清单中的主题。
• 在 UnityPlayerActivity Java 类中设置主题。
• 通过将具有更新主题的清单放在 Unity 目录 /Assets/Plugins/Android 中来覆盖 Unity Android 清单。
• 更改 UnityPlayerActivity 以扩展 AppCompatActivity。这将显示操作栏，但它与状态栏之间存在白色间隙。
• 在 Unity SceneManager 中设置“Screen.fullScreen = false;”。这将删除沉浸式模式，以便 Android 状态栏可见。
• 关闭播放器设置中的“状态栏隐藏”。似乎没有效果。
• 将 UnityPlayer 包装在 FrameLayout 中。这使我能够将 Unity 的大小调整为视图。
