Android UnityPlayerActivity操作欄

Question

我正在構建一個包含Unity 3d交互體驗的Android應用程序。

我已經將Unity項目導入到Android Studio中，但啓動時該活動是全屏顯示並且不顯示Android操作欄。

我該怎麼做？

整合步伐

• 創建新的統一的項目。
• 從Unity導出「Google Android Project」。
• 將項目導入Android Studio。

嘗試的解決方案

• 更改清單中的主題。
• 在UnityPlayerActivity Java類中設置主題。
• 通過將具有更新主題的清單放置在Unity目錄/ Assets/Plugins/Android中，覆蓋Unity Manifest。
• 更改UnityPlayerActivity以擴展AppCompatActivity。這將顯示操作欄，但它與狀態欄之間存在白色間隙。
• 設置「Screen.fullScreen = false;」在Unity SceneManager中。這將刪除沉浸式模式，以便Android狀態欄可見。
• 在播放器設置中關閉「狀態欄隱藏」。似乎沒有效果。
• 在FrameLayout中包裝UnityPlayer。這使我可以將Unity作爲視圖調整大小。

AndroidManifest.xml中

Answer 1

我想我已經找到了解決方案。
更改了該行：

mUnityPlayer = new UnityPlayer(this); 

因此它會創建自己的UnityPlayer子類，它覆蓋setFullscreen方法（有點哈克）：

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

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

另外，請刪除該行：requestWindowFeature(Window.FEATURE_NO_TITLE);

Answer 2

適用於Unity版本5.5避免Android中Immersive Mode的最好方法是在構造函數中傳遞Activity而不是將ApplicationContext轉換爲Wrapper Context。

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

，由於在混淆UnityPlayer.class工程（團結-classes.jar）有實例的檢查。

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

所以，如果它不是一個活動UnityPlayer.class不設置標誌。

Answer 3

彼得回答正在爲舊版本和洛倫佐DM的回答也是有效的，但

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

在某些設備不工作。所以，最後我在這裏修改UnityPlayerActivity是新的解決方案

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() 
    { 
     super.onResume(); 
     mUnityPlayer.resume(); 
    } 

    // Low Memory Unity 
    @Override public void onLowMemory() 
    { 
     super.onLowMemory(); 
     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); 
     mUnityPlayer.windowFocusChanged(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); } 
    @Override public boolean onTouchEvent(MotionEvent event)   { return mUnityPlayer.injectEvent(event); } 
    /*API12*/ public boolean onGenericMotionEvent(MotionEvent event) { return mUnityPlayer.injectEvent(event); } 
}
