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。

我该怎么做？

整合步骤

创建新的Unity项目。
导出＆＃34;谷歌Android项目＆＃34;来自Unity。
将项目导入Android Studio。

尝试解决方案

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中放置包含更新主题的清单来覆盖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空白。
设置＆＃34; Screen.fullScreen = false;＆＃34;在Unity SceneManager中。这将删除沉浸式模式，以便可以看到Android状态栏。
关闭＆＃34;状态栏隐藏＆＃34;在播放器设置中。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。

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强制转换为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，如果它不是活动，则UnityPlayer.class不会设置标记。

我想我找到了解决办法改变那一行：

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);
    }
}

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

Answer 3

Piotr的答案适用于旧版本，Lorenzo DM的答案也有效，但

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

无法在某些设备上使用。所以最后我修改UnityPlayerActivity这里是新的解决方案



public class UnityPlayerActivity extends AppCompatActivity
{
    protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code
    ActionBar actionBar;
    private Toolbar toolbar;
    private FrameLayout unityContainer;

    // Setup activity layout
    @Override protected void onCreate (Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        mUnityPlayer = new UnityPlayer(this);
        setContentView(R.layout.activity_unity_player);
        mappingWidgets();
        init();

    }

    void  mappingWidgets(){
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        unityContainer = (FrameLayout) findViewById(R.id.unity_container);
        FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT);
        unityContainer.addView(mUnityPlayer.getView(), 0, layoutParams);
        mUnityPlayer.requestFocus();

    }
    void init(){
        setSupportActionBar(toolbar);
        actionBar = getSupportActionBar();
        if (actionBar != null)
            actionBar.setDisplayHomeAsUpEnabled(true);
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();
                onDestroy();
            }
        });
        setTitle(getString(R.string.app_name));


    }


    @Override protected void onNewIntent(Intent intent)
    {
        setIntent(intent);
    }

    // Quit Unity
    @Override protected void onDestroy ()

        mUnityPlayer.quit();
        super.onDestroy();
    }

    // Pause Unity
    @Override protected void onPause()
    {
        super.onPause();
        mUnityPlayer.pause();
    }

    // Resume Unity
    @Override protected void onResume()
    {

        mUnityPlayer.lowMemory();
    }

    // Trim Memory Unity
    @Override public void onTrimMemory(int level)
    {
        super.onTrimMemory(level);
        if (level == TRIM_MEMORY_RUNNING_CRITICAL)
        {
            mUnityPlayer.lowMemory();
        }
    }

    // This ensures the layout will be correct.
    @Override public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);
        mUnityPlayer.configurationChanged(newConfig);
    }

    // Notify Unity of the focus change.
    @Override public void onWindowFocusChanged(boolean hasFocus)
    {
        super.onWindowFocusChanged(hasFocus);

    }

    // For some reason the multiple keyevent type is not supported by the ndk.
    // Force event injection by overriding dispatchKeyEvent().
    @Override public boolean dispatchKeyEvent(KeyEvent event)
    {
        if (event.getAction() == KeyEvent.ACTION_MULTIPLE)
            return mUnityPlayer.injectEvent(event);
        return super.dispatchKeyEvent(event);
    }

    // Pass any events not handled by (unfocused) views straight to UnityPlayer
    //@Override public boolean onKeyUp(int keyCode, KeyEvent event)     { return mUnityPlayer.injectEvent(event); }
    // Pass any events not handled by (unfocused) views straight to UnityPlayer
    @Override public boolean onKeyUp(int keyCode, KeyEvent event)     {
        if(keyCode == KeyEvent.KEYCODE_BACK) {
            finish();
            onDestroy();
            return true;
        }
        return mUnityPlayer.injectEvent(event); }
    @Override public boolean onKeyDown(int keyCode, KeyEvent event)   { return mUnityPlayer.injectEvent(event); }
