java - Android UnityPlayerActivity 操作栏

Question

我正在构建一个包含 Unity 3d 交互体验的 Android 应用程序。

我已将 Unity 项目导入 Android Studio，但启动时 Activity 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 项目”。
• 将项目导入 Android Studio。

尝试的解决方案

• 更改 list 中的主题。
• 在 UnityPlayerActivity Java 类中设置主题。
• 通过在 Unity 目录/Assets/Plugins/Android 中放置具有更新主题的 list 来覆盖 Unity Android list 。
• 更改 UnityPlayerActivity 以扩展 AppCompatActivity。这将显示操作栏，但它和状态栏之间有一个白色间隙。
• 设置“Screen.fullScreen = false；”在 Unity 场景管理器中。这会移除沉浸式模式，以便 Android 状态栏可见。
• 在播放器设置中关闭“隐藏状态栏”。似乎没有效果。
• 将 UnityPlayer 包装在 FrameLayout 中。这允许我调整 Unity 作为 View 的大小。

Answer 1

对于 Unity 5.5 版，避免 Android 中沉浸模式的最佳方法是传入构造函数而不是 Activity，而是将 ApplicationContext 转换为 Wrapper Context。

mUnityPlayer = new UnityPlayer((ContextWrapper) getApplicationContext());

这是可行的，因为在混淆后的 UnityPlayer.class(在 unity-classes.jar 中)有一个实例检查。

 private void h() {
     if(this.h instanceof Activity) {
        ((Activity)this.h).getWindow().setFlags(1024, 1024);
     }
 }

因此，如果它不是 Activity，则 UnityPlayer.class 不会设置标志。
