在Unity Android/Eclipse项目中检测启动屏幕退出

Question

我已经根据指示here创建了基于Vuforia/Unity项目的Eclipse项目。这是正在运行。

我在我的主要活动中添加一个按钮，从QCARPlayerActivity扩展。这也适用，但是，随着Unity启动画面播放，该按钮位于Unity播放器的顶部。

有没有什么办法可以检测Unity启动画面何时退出，因此在场景加载前我没有控制权？

UPDATE 13年3月18日

我添加了一个静态布尔我在Eclipse中的主要活动跟踪闪屏完成，修改，增加了控制观看布尔的代码。

MainActivity.java

public static boolean splashComplete = false; 
private View mControlViewContainer = null; // initialized in onCreate 

class QCARViewFinderTask extends TimerTask { 
    public void run() { 
     MainActivity.this.runOnUiThread(new Runnable() { 
      public void run() { 
       if (!QCAR.isInitialized()) return; //wait for QCAR init 
//search for QCAR view if it hasn't been found 
       if (mQCARView == null) 
       { 
        View rootView = MainActivity.this.findViewById(android.R.id.content); 
        QCARUnityPlayer qcarView = findQCARView(rootView); 
        if (qcarView != null) { 
         mQCARParentView = (ViewGroup)(qcarView.getParent()); 
         mQCARView = qcarView; 
        } 
       }      

       // add controls if QCAR view is located and the splash sequence is complete 
       if(mQCARView != null && splashComplete && mControlViewContainer != null){ 
        mQCARParentView.addView(mControlViewContainer); 
        mViewFinderTimer.cancel(); 
        mViewFinderTimer = null; 
       } 
      } 
     }); 
    } 
} 

在Unity我创建了一个简单的脚本来设置Java中的静态布尔和它连接到Vuforia ARCamera

SplashExit.js

function Start() { 
    var mainActivity = new AndroidJavaClass ("com.example.app.MainActivity"); 
    mainActivity.SetStatic.("splashComplete",true); 
} 

这在一个场景简单的项目中工作得很好。我的控件似乎在飞溅退出时加载。然而，当我在更复杂的场景中使用这种方法时，控制器会在启动画面消失之前出现一秒钟左右。

是否有更好的地方可以将我的Unity脚本或更好的方法附加到脚本中，以更准确地反映飞溅序列何时退出？也许杰尔达克在评论中的建议？

添加yield语句的确有用。完整的解决方案

SplashExit.js应附于在Unity ARCamera游戏对象。启动方法将暂停，直到场景加载完毕，然后在MainActivity.java中将splashComplete设置为true。

如MainActivity.java定时器重复调用QCARViewFinderTask的运行方法，所述控制视图将被添加到作为splashComplete转换为true统一播放父视图。

MainActivity.java

public class MainActivity extends QCARPlayerActivity { 
    private QCARUnityPlayer mQCARView = null; 
    private ViewGroup mQCARParentView = null; 
    private Timer mViewFinderTimer = null; 
    private View mControlViewContainer = null; 

    public static boolean splashComplete = false; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     mControlViewContainer = getLayoutInflater().inflate(R.layout.control_layout, null); 
    } 

    @Override 
    public void onResume() { 
     super.onResume(); 
     if (mQCARView == null) { 
      //search the QCAR view 
      mViewFinderTimer = new Timer(); 
      mViewFinderTimer.scheduleAtFixedRate(new QCARViewFinderTask(), 1000, 1000); 
     } 
    } 

    @Override 
    public void onPause() { 
     super.onPause(); 
     if (mViewFinderTimer != null) { 
      mViewFinderTimer.cancel(); 
      mViewFinderTimer = null; 
     } 
    } 

    class QCARViewFinderTask extends TimerTask { 
     public void run() { 
      MainActivity.this.runOnUiThread(new Runnable() { 
       public void run() { 
        if (!QCAR.isInitialized()) return; //wait for QCAR init 

        //search for QCAR view if it hasn't been found 
        if (mQCARView == null) 
        { 
         View rootView = MainActivity.this.findViewById(android.R.id.content); 
         QCARUnityPlayer qcarView = findQCARView(rootView); 
         if (qcarView != null) { 
          mQCARParentView = (ViewGroup)(qcarView.getParent()); 
          mQCARView = qcarView; 
         } 
        }      

        // add controls if QCAR view is located and the splash sequence is complete 
        if(mQCARView != null && splashComplete && mControlViewContainer != null){ 
         mQCARParentView.addView(mControlViewContainer); 
         mViewFinderTimer.cancel(); 
         mViewFinderTimer = null; 
        } 
       } 
      }); 
     } 

     private QCARUnityPlayer findQCARView(View view) { 
      if (view instanceof QCARUnityPlayer) { 
       return (QCARUnityPlayer)view; 
      } 
      if (view instanceof ViewGroup) { 
       ViewGroup vg = (ViewGroup)view; 
       for (int i = 0; i

SplashExit.js

function Start() { 
    yield; // wait for the scene to fully load 
    // Note that com.example.app.MainActivity should be updated to match your bundle identifier and class names 
    var mainActivity = new AndroidJavaClass ("com.example.app.MainActivity"); 
    mainActivity.SetStatic.("splashComplete",true); 
}
