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 支援刊登固定大小的廣告。
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。任何邊框間距都會有效縮減容器大小。如果容器無法容納橫幅廣告，系統就不會顯示廣告，並記錄下列警告：
W/Ads: Not enough space to show ad. Needs 320x50 dp, but only has 288x495 dp.
在版面配置中新增 AdManagerAdView
除了以程式輔助方式建立 AdManagerAdView，您也可以將 AdManagerAdView 加入要顯示 Activity 或 Fragment 的 XML 版面配置。範例如下：
<com.google.android.gms.ads.admanager.AdManagerAdView
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="/21775744923/example/fixed-size-banner" />
請注意下列必要屬性：
自訂廣告大小
如果您有指定自訂大小的 Ad Manager 預訂委刊項，可以建立符合委刊項的自訂寬度和高度的 AdSize。
Java
AdSize customAdSize = new AdSize(250, 250);
AdManagerAdView adView = new AdManagerAdView(this);
adView.setAdSizes(customAdSize);
Kotlin
val customAdSize = AdSize(250, 250)
val adView = AdManagerAdView(this)
adView.setAdSizes(customAdSize)
多種廣告大小
如要在同一個廣告請求中指定多個廣告大小的委刊項，請使用 AdManagerAdView 一次設定多個廣告大小。
Java
AdManagerAdView adView = new AdManagerAdView(this);
adView.setAdSizes(AdSize.BANNER, new AdSize(120, 20), new AdSize(250, 250));
Kotlin
val adView = AdManagerAdView(this)
adView.setAdSizes(AdSize.BANNER, AdSize(120, 20), AdSize(250, 250))
AdManagerAdView 預設為第一個廣告大小。廣告載入後，AdManagerAdView大小會變更為載入的廣告大小。版面配置應能自動配合新尺寸調整。
您也可以在 XML 版面配置檔案中使用 ads:adSizes 屬性指定多個廣告尺寸：
<com.google.android.gms.ads.admanager.AdManagerAdView
android:id="@+id/multiple_ad_sizes_view"
android:layout_width="wrap_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
ads:adSizes="BANNER,120x20,250x250"
ads:adUnitId="AD_UNIT_ID" />

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 AdManagerAdView to the layout\n\nAlternative to creating the `AdManagerAdView`\nprogrammatically, add the `AdManagerAdView` 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.admanager.AdManagerAdView\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=\"/21775744923/example/fixed-size-banner\" /\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\nCustom ad size\n\nIf you have Ad Manager reservation [line items](//support.google.com/admanager/answer/9405477) targeting a custom size, you can\ncreate an `AdSize` with a custom width and height that matches your line item. \n\nJava \n\n AdSize customAdSize = new AdSize(250, 250);\n AdManagerAdView adView = new AdManagerAdView(this);\n adView.setAdSizes(customAdSize);\n\nKotlin \n\n val customAdSize = AdSize(250, 250)\n val adView = AdManagerAdView(this)\n adView.setAdSizes(customAdSize)\n\n\u003cbr /\u003e\n\nMultiple ad sizes\n\nIf you want to target line items of multiple ad sizes in the same ad request,\n`AdManagerAdView` lets you set multiple ad sizes at once. \n\nJava \n\n AdManagerAdView adView = new AdManagerAdView(this);\n adView.setAdSizes(AdSize.BANNER, new AdSize(120, 20), new AdSize(250, 250));\n\nKotlin \n\n val adView = AdManagerAdView(this)\n adView.setAdSizes(AdSize.BANNER, AdSize(120, 20), AdSize(250, 250))\n\nThe `AdManagerAdView` defaults to the first ad size. Once the ad loads, the\n`AdManagerAdView` size changes to the loaded ad size. Your layout should\nbe able to automatically adapt to the new size.\n\nYou can also specify multiple ad sizes using the `ads:adSizes` attribute in your\nXML layout file: \n\n \u003ccom.google.android.gms.ads.admanager.AdManagerAdView\n android:id=\"@+id/multiple_ad_sizes_view\"\n android:layout_width=\"wrap_parent\"\n android:layout_height=\"wrap_content\"\n android:layout_alignParentBottom=\"true\"\n android:layout_centerHorizontal=\"true\"\n ads:adSizes=\"BANNER,120x20,250x250\"\n ads:adUnitId=\"\u003cvar translate=\"no\"\u003eAD_UNIT_ID\u003c/var\u003e\" /\u003e\n\nMultiple ad sizes 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/AdManagerMultipleAdSizesFragment.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/AdManagerMultipleAdSizesFragment.kt)\n\n\u003cbr /\u003e"]]
