检测Unity Android/Eclipse项目上的启动屏幕退出

我按照说明创建了一个基于Vuforia/Unity项目的Eclipse项目。那就开始运行了

我在我的主要活动中添加了一个按钮，扩展自QCarPlayerPractivity。但是，当Unity启动屏幕播放时，按钮位于Unity播放器的顶部

有没有办法检测Unity启动屏幕何时退出，这样在加载场景之前我就没有控制了

2013年3月18日更新

我在Eclipse中的主要活动中添加了一个静态布尔值来跟踪启动屏幕的完成情况，并修改了添加控件以观察布尔值的代码

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;
                }
            }
        });
    }
}

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
在Unity中，我创建了一个简单的脚本来设置Java中的静态布尔值，并将其附加到Vuforia ARCamera

SplashExit.js

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

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);
}

这在具有简单场景的项目中非常有效。我的控件似乎加载到飞溅出口。然而，当我在更复杂的场景中使用这种方法时，控件会在闪屏消失前出现一秒钟左右

是否有更好的地方附加我的Unity脚本，或者脚本中有更好的方法，可以更准确地反映启动序列退出时的情况？也许Jerdak在评论中的建议？

添加收益率声明起到了作用。完整的解决方案如下

SplashExit.js应该连接到Unity中的ARCamera游戏对象。start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

当MainActivity.java中的计时器反复调用QCARViewFinderTask的run方法时，控件视图将在转换为true时添加到Unity Player父视图中

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;

unity标签是针对Microsoft unity的。请不要误用它。我假设这是unity basic，具有unity iOS许可证？除非使用干净的方法，否则您是否可以创建一个空的级别，并使用调用Application.LoadLevel的单个脚本来加载您的实际级别？我记不起是在所有级别加载之间还是在启动应用程序时显示飞溅@Jerdak这是Unity Pro和Unity Android许可证。我可能没有遵循，但我不确定如何使用此方法在启动序列完成时通知我的包装器活动。@JasonGeorge我使用移动许可证已经有一段时间了，但在PC上，启动仅在第一级加载之前显示，因此我对创建虚拟级别。但是如果你只是想找一个触发splashComplete的地方，怎么样。@Jerdak我尝试了onlevelwasload，但似乎没有触发。在设置splashComplete变量之前添加一个屈服值就成功了。它似乎会暂停例程，直到第一帧有机会渲染为止。
