AndroidAndEngine游戏启动画面中移除广告

在使用AndEngine开发Android游戏时，一个常见的问题是广告会在游戏数据加载期间（大约5-6秒）短暂显示。这不仅影响用户体验，还可能分散玩家的注意力。如何在启动画面中移除这些广告呢？

一种有效的方法是通过调整XML布局文件和代码逻辑来控制广告的显示时机。

首先，在布局文件中定义广告视图，并将其初始状态设置为不可见：

    android:id="@+id/footer_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:gravity="bottom"
    android:orientation="vertical" >
            xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ads:adSize="BANNER"
        ads:adUnitId="@string/admob_id"
        android:visibility="gone" />

接下来，在代码中处理广告的加载时机。可以在游戏资源和场景加载完成后，再加载广告：

@Override
protected void onSetContentView() {
    RelativeLayout relativeLayout = new RelativeLayout(this);
    FrameLayout.LayoutParams relativeLayoutLayoutParams = new FrameLayout.LayoutParams(
        FrameLayout.LayoutParams.MATCH_PARENT,
        FrameLayout.LayoutParams.MATCH_PARENT);
    mRenderSurfaceView = new RenderSurfaceView(this);
    mRenderSurfaceView.setRenderer(mEngine, this);
    RelativeLayout.LayoutParams surfaceViewLayoutParams = new RelativeLayout.LayoutParams(
        super.createSurfaceViewLayoutParams());
    surfaceViewLayoutParams.addRule(RelativeLayout.CENTER_IN_PARENT);
    // 加载AndEngine视图
    relativeLayout.addView(mRenderSurfaceView, surfaceViewLayoutParams);
    // 加载XML视图
    LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View vv = vi.inflate(R.layout.main, null);
    vv.bringToFront();
    vv.setVisibility(View.GONE);
    relativeLayout.addView(vv, createAdViewLayoutParams());
    setContentView(relativeLayout, relativeLayoutLayoutParams);
}

在加载启动画面资源和场景时，确保广告视图保持不可见：

@Override
public void onCreateResources(OnCreateResourcesCallback pOnCreateResourcesCallback) throws Exception {
    splashBackgroundTextureAtlas = new BitmapTextureAtlas(getTextureManager(), 480, 800, TextureOptions.NEAREST);
    splashBackgroundTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(splashBackgroundTextureAtlas, this, "gfx/splash.png", 0, 0);
    mEngine.getTextureManager().loadTexture(splashBackgroundTextureAtlas);
    pOnCreateResourcesCallback.onCreateResourcesFinished();
}
@Override
public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback) throws Exception {
    splashScene = new Scene();
    splashScene.setBackgroundEnabled(false);
    splashScene.attachChild(new Sprite(0, 0, splashBackgroundTextureRegion, this.getVertexBufferObjectManager()));
    pOnCreateSceneCallback.onCreateSceneFinished(splashScene);
}

在游戏资源和场景加载完成后，再加载广告：

@Override
public void onPopulateScene(Scene pScene, OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception {
    mEngine.registerUpdateHandler(new TimerHandler(0.01f, new ITimerCallback() {
        public void onTimePassed(final TimerHandler pTimerHandler) {
            mEngine.unregisterUpdateHandler(pTimerHandler);
            loadResources();
            loadScene();
            mEngine.setScene(scene);
            runOnUiThread(new Runnable() {
                public void run() {
                    View vv = findViewById(R.id.footer_layout);
                    vv.setVisibility(View.VISIBLE);
                    AdView adView = (AdView) findViewById(R.id.adView);
                    adView.loadAd(new AdRequest());
                }
            });
        }
    }));
    pOnPopulateSceneCallback.onPopulateSceneFinished();
}

通过上述步骤，可以有效地在游戏启动画面中移除广告，提升用户体验。
