Admob 自适应横幅广告实施

Question

我正在用新的自适应横幅广告替换我当前的横幅广告。自适应广告尺寸是在捕获宽度尺寸后计算的。我将 adview 的 framelayout 放在布局的底部。

<Relativelayout>
..
//// linear layout above ad_view_container   
<FrameLayout
        android:id="@+id/ad_view_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_alignParentBottom="true" />

</Relativelayout>

但现在的问题是，首先加载整个页面，然后在 1 -2 秒后，整个布局向上移动并显示 adative 横幅广告。

那么这是否违反了 admob 政策？这种情况应该如何处理，我应该为自适应广告设置高度，这样布局就不会发生上移？搜索了很多，但没有找到答案。提前致谢。

我不确定，如果您的唯一意图是询问这是否违反政策。

但为了防止布局在一段时间后发生变化，我使用以下实现。 当您像我一样有更复杂的布局组合时，它也会有所帮助。我使用ConstraintLayout 在纵向模式下将我的屏幕分成两部分。横幅位于这两个部分之一中，它们之间的比例不是固定的，而是取决于某些逻辑。因此，此实现也适用于此要求，因为它会覆盖 onMeasure 以根据可用宽度确定最佳尺寸。

public class AdBanner extends FrameLayout
{
    private AdView mAdView;
    private final DisplayMetrics mDisplayMetrics = new DisplayMetrics();

    public AdBanner(Context context)
    {
        super(context);
    }

    public AdBanner(Context context, AttributeSet attrs)
    {
        super(context, attrs);
    }

    public AdBanner(Context context, AttributeSet attrs, int defStyleAttr)
    {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
        if (!isShowBanner())
        {
            super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.AT_MOST));
            return;
        }
        int width = MeasureSpec.getSize(widthMeasureSpec);
        if (width <= 0)
        {
            super.onMeasure(widthMeasureSpec, heightMeasureSpec);
            return;
        }
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        // That's where we determine the most accurate banner format.
        AdSize adSize = AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(getContext(), getDpWidth(width));
        int height = adSize.getHeightInPixels(getContext());
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        if (heightMode != MeasureSpec.UNSPECIFIED)
        {
            height = Math.min(height, MeasureSpec.getSize(heightMeasureSpec));
        }
        setMeasuredDimension(widthMeasureSpec, MeasureSpec.makeMeasureSpec(height, MeasureSpec.getMode(heightMeasureSpec)));
    }

    protected int getDpWidth(int width)
    {
        Display display = ((WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
        display.getMetrics(mDisplayMetrics);
        return (int) (width / mDisplayMetrics.density);
    }

    protected boolean isShowBanner()
    {
        // Do your checks here, like whether the user payed for ad removement.
    }

    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b)
    {
        if (!isShowBanner())
        {
            return;
        }
        int width = r - l;
        if (width <= 0)
        {
            return;
        }
        AdSize adSize = AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(getContext(), getDpWidth(width));

        // Prevent the ad from beeing added with each layout cicle,
        // by checking, whether or not available size actually changed the format of the banner
        if (mAdView == null || !adSize.equals(mAdView.getAdSize()))
        {
            removeAllViews();
            mAdView = new AdView(getContext());
            mAdView.setAdSize(adSize);
            ((GameApplication) getContext().getApplicationContext()).androidInjector().getAdService().loadBannerAd(getRootActivity(this), mAdView);
            this.addView(mAdView);
        }
        mAdView.layout(0, 0, width, b - t);
    }
}

为此，您可以使用以下代码

public class MainActivity extends AppCompatActivity {

private FrameLayout adContainerView;
private AdView adView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Initialize the Mobile Ads SDK.
    MobileAds.initialize(this, new OnInitializationCompleteListener() {
        @Override
        public void onInitializationComplete(InitializationStatus initializationStatus) { }
    });
    adContainerView = findViewById(R.id.ad_view_container);
    // Step 1 - Create an AdView and set the ad unit ID on it.
    adView = new AdView(this);
    adView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");
    adContainerView.addView(adView);
    loadBanner();
}

private void loadBanner() {
    // Create an ad request. 
    AdRequest adRequest =
            new AdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                    .build();

    AdSize adSize = getAdSize();
    // Step 4 - Set the adaptive ad size on the ad view.
    adView.setAdSize(adSize);

    // Step 5 - Start loading the ad in the background.
    adView.loadAd(adRequest);
}

private AdSize getAdSize() {
    // Step 2 - Determine the screen width (less decorations) to use for the ad width.
    Display display = getWindowManager().getDefaultDisplay();
    DisplayMetrics outMetrics = new DisplayMetrics();
    display.getMetrics(outMetrics);

    float widthPixels = outMetrics.widthPixels;
    float density = outMetrics.density;

    int adWidth = (int) (widthPixels / density);

    // Step 3 - Get adaptive ad size and return for setting on the ad view.
    return AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(this, adWidth);
}
}
