Android UnityPlayerActivity动作栏

Question

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,但在启动时,活动是全屏的,并未显示Android操作栏.

我怎样才能做到这一点？

整合步骤

• 创建新的Unity项目.
• 从Unity导出"Google Android Project".
• 将项目导入Android Studio.

试图解决方案

• 更改清单中的主题.
• 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清单来覆盖Unity Android Manifest.
• 更改UnityPlayerActivity以扩展AppCompatActivity.这将显示操作栏,但它与状态栏之间存在空白.
• 设置"Screen.fullScreen = false;" 在Unity SceneManager中.这将删除沉浸式模式,以便可以看到Android状态栏.
• 在播放器设置中关闭"状态栏隐藏".似乎没有效果.
• 在FrameLayout中包装UnityPlayer.这允许我将Unity的大小调整为视图.

import com.unity3d.player.UnityPlayer;

public class UnityPlayerActivity extends Activity
{
    protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code

    // Setup activity layout

Answer 1

对于Unity版本5.5,在Android中避免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());

这是有效的,因为在混淆的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.

Answer 2

我想我已经找到解决方案了。
更改该行：

mUnityPlayer = new UnityPlayer(this);

所以它创建了你自己的UnityPlayer子类，它覆盖了setFullscreen方法（有点hacky）：

public class UnityPlayerWrapper extends UnityPlayer {
    public UnityPlayerWrapper(ContextWrapper contextWrapper) {
        super(contextWrapper);
    }

    @Override
    protected void setFullscreen(boolean b) {
        super.setFullscreen(false);
    }
}

另外，请删除该行：requestWindowFeature(Window.FEATURE_NO_TITLE);
