Question

我尝试创建简单的mesured时间标签。我尝试RunnableHandler，Handler和activity.this.runOnUiThread（）。每次我都有类似的错误。

错误

我当前的代码

@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));
}

你可以告诉我我做错了什么吗？我正在使用最新的AndEngine和GLES 2。

不要使用这些会在每次更新时更新的处理程序（在您的情况下，它会多次加载所有资源）。尝试使用一个处理程序本身。并在完成加载资源后取消注册此句柄。

Andengine更新计时器标签
