Andengine更新計時器標籤

Question

我嘗試創建簡單的已標記時間標籤。我嘗試了RunnableHandler，Handler和activity.this.runOnUiThread（）。每次我有類似的錯誤。

我當前的代碼

@Override 
public void onPopulateScene(Scene pScene, OnPopulateSceneCallback pOnPopulateSceneCallback) throws IOException { 
    final Thread backgroundLoading = new Thread(new Runnable() { 
     @Override 
     public void run() { 
      loadResources(); 
      loadScenes(); 
      Handler refreshScene = new Handler(Looper.getMainLooper()); 
      refreshScene.post(new Runnable() { 

       @Override 
       public void run() { 
        loadingIndicator.detachSelf(); 
        splash.detachSelf(); 
        mEngine.setScene(mainScene); 
       } 
      }); 

     } 
    }); 
    mEngine.registerUpdateHandler(new TimerHandler(1f, new ITimerCallback() { 

     @Override 
     public void onTimePassed(TimerHandler pTimerHandler) { 
      backgroundLoading.start(); 
     } 
    })); 

    mEngine.registerUpdateHandler(new TimerHandler(1f, new ITimerCallback() { 

     @Override 
     public void onTimePassed(TimerHandler pTimerHandler) { 
      // TODO Auto-generated method stub 
      initLoadingAnimation(); 
     } 
    })); 

    pOnPopulateSceneCallback.onPopulateSceneFinished(); 

} 


private void loadScenes() { 
    mainScene = ((MenuController) mFrame.getModule("Menu")).createMainMenu(); 
    final Handler updateLabel = new Handler(Looper.getMainLooper()); 
    Font font = FontFactory.create(this.getFontManager(), this.getTextureManager(), 256, 256, Typeface.create(Typeface.DEFAULT, Typeface.BOLD), 32); 
    font.load(); 
    // 
    Float timerText = 0.0f; 
    timerLabel = new Text(CAMERA_WIDTH/2, CAMERA_HEIGHT/2, font, Float.toString(timerText), this.getVertexBufferObjectManager()); 
    TimerHandler mTime = new TimerHandler(0.1f, true, new ITimerCallback() { 

     float time = 0.0f; 

     @Override 
     public void onTimePassed(TimerHandler pTimerHandler) { 
      time += 0.1f; 
      updateLabel.post(new Runnable() { 

       @Override 
       public void run() { 
        updateTimerText(time); 

       } 
      }); 

     } 

    }); 

    mainScene.attachChild(timerLabel); 
    mainScene.registerUpdateHandler(mTime); 
} 

void updateTimerText(float value) { 
    timerLabel.setText(Float.toString(value)); 
} 

你可以建議我什麼，我做錯了嗎？我正在使用最新的AndEngine和GLES 2.

不要使用這些會每次更新的處理程序（在您的情況下它會多次加載所有資源）。嘗試使用一個處理程序本身。並且還要取消註冊這個句柄在完成加載你的資源之後。
