大小固定的橫幅廣告
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
如果自動調整橫幅廣告不符合需求，Google Mobile Ads SDK 也支援固定大小的廣告。
下表列出標準橫幅大小。
展示廣告的容器至少必須與橫幅一樣大。任何邊框間距都會縮減容器的實際可用空間。如果容器無法容納橫幅廣告，系統將不會顯示廣告，並會記錄下列警告：
W/Ads: Not enough space to show ad. Needs 320x50 dp, but only has 288x495 dp.
將 AdView 新增至版面配置
除了以程式輔助方式建立 AdView，您也可以將 AdView 加入要顯示 Activity 或 Fragment 的 XML 版面配置。範例如下：
<com.google.android.gms.ads.AdView
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:id="@+id/banner_ad_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
ads:adSize="BANNER"
ads:adUnitId="ca-app-pub-3940256099942544/6300978111" />

Any padding effectively decreases the size of your container. If the\ncontainer cannot fit the banner ad, the ad isn't shown and the following\nwarning is logged: \n\n W/Ads: Not enough space to show ad. Needs 320x50 dp, but only has 288x495 dp.\n\nAdd AdView to the layout\n\nAlternative to creating the `AdView`\nprogrammatically, add the `AdView` to the XML layout\nfor the `Activity` or `Fragment` in which you'd like to display\nit. Here's an example: \n\n \u003ccom.google.android.gms.ads.AdView\n xmlns:ads=\"http://schemas.android.com/apk/res-auto\"\n android:id=\"@+id/banner_ad_view\"\n android:layout_width=\"wrap_content\"\n android:layout_height=\"wrap_content\"\n android:layout_centerHorizontal=\"true\"\n android:layout_alignParentBottom=\"true\"\n ads:adSize=\"BANNER\"\n ads:adUnitId=\"ca-app-pub-3940256099942544/6300978111\" /\u003e\n\nNote the following required attributes:\n\n- `ads:adSize`: Set this to the ad size you'd like to use. If you don't want to\n use the standard size defined by the constant, you can set a custom size\n instead. Example: `ads:adSize=\"320x50\"`.\n\n- `ads:adUnitId`: Set this to the ad unit in your app where ads are to be\n displayed. If you show banner ads in different activities, each would require\n an ad unit.\n\n\u003cbr /\u003e\n\nFixed size banner ads example\n\n[Java](//github.com/googleads/googleads-mobile-android-examples/blob/main/java/advanced/APIDemo/app/src/main/java/com/google/android/gms/example/apidemo/AdMobBannerSizesFragment.java)\n[Kotlin](//github.com/googleads/googleads-mobile-android-examples/blob/main/kotlin/advanced/APIDemo/app/src/main/java/com/google/android/gms/example/apidemo/AdMobBannerSizesFragment.kt)"]]
