您可以在这里查看GitHub上的横幅广告集成代码示例。
您可以在 XML 布局资源文件中添加横幅广告，并像在常规视图中一样在代码中引用它。
以下代码片段展示了如何在 XML 中添加横幅广告。请注意，您需要将 InMobi 广告命名空间添加到顶级布局元素中才能添加横幅广告。

<androidx.constraintlayout.widget.constraintlayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://"schemas.android.com/apk/res-auto"
xmlns:ads="http://"schemas.android.com/apk/lib/com.inmobi.ads"
xmlns:tools="http://"schemas.android.com/tools"
对于横幅广告 XML 集成，使用 Android SDK 720 及更高版本的发布商需要将“plid-”附加到placementIdTAG，如下所示：
ads:placementId="plid-1431977751489005"
现在，您可以在代码中引用该横幅广告：
InMobiBanner bannerAd = (InMobiBanner)findViewById(R.id.banner);
val bannerAd:InMobiBanner = findViewById(R.id.banner)
获得横幅实例后，您可以按照以下各节所示请求加载广告。
在此之前，请InMobiSdk.init(Context, String)在您的主活动或显示横幅广告的活动中调用该方法来初始化 InMobi SDK。
要在 Android 代码中添加横幅广告，请创建以下实例InMobiBanner：
InMobiBanner bannerAd = new InMobiBanner(BannerAdsActivity.this, 1468078426600L);
val bannerAd = InMobiBanner(this@BannerAdsActivity, 1468078426600L)
InMobiBanner 不是线程安全的。横幅实例必须在 UI 线程上创建。创建横幅广告后，您可以将其添加到视图层级结构中：
RelativeLayout adContainer = (RelativeLayout) findViewById(R.id.ad_container);
RelativeLayout.LayoutParams bannerLp = new RelativeLayout.LayoutParams( < WIDTH_IN_PIXEL > , < HEIGHT_IN_PIXEL > );
bannerLp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
bannerLp.addRule(RelativeLayout.CENTER_HORIZONTAL);
adContainer.addView(bannerAd, bannerLayoutParams);
val adContainer:RelativeLayout = findViewById(R.id.ad_container)
val bannerLp:RelativeLayout.LayoutParams = RelativeLayout.LayoutParams( < WIDTH_IN_PIXEL > , < HEIGHT_IN_PIXEL > )
bannerLp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM)
bannerLp.addRule(RelativeLayout.CENTER_HORIZONTAL)
adContainer.addView(bannerAd, bannerLayoutParams)
WRAP_CONTENT此外，将布局参数作为横幅广告的布局参数是编程错误。无论您是在 XML 布局资源文件中创建横幅广告，还是在代码中创建，此限制都适用。MATCH_PARENT将横幅广告的布局参数提供给 InMobi SDK。InMobi SDK 将正确计算横幅广告的视图尺寸，并使用这些信息从 InMobi 广告网络中获取广告。加载横幅广告需要先将横幅广告视图添加到视图层级结构中，然后再向实例请求广告InMobiBanner。将视图添加到视图层级结构后，InMobi SDK 才能正确计算横幅广告视图的尺寸，并从网络中请求与这些尺寸最匹配的广告。
将视图添加InMobiBanner到视图层次结构后，就可以调用load()刚刚创建的实例上的方法来请求广告。
首次通过调用实例请求广告后，横幅广告会自动刷新load()。InMobiBanner您可以在创建横幅广告时（在 XML 布局资源文件中）设置自动刷新，也可以稍后在代码中通过调用setRefreshInterval(int)横幅广告的相应方法来设置。
以下示例展示了如何在 XML 中实现此功能：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.inmobi.ads"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
...
>
<com.inmobi.ads.InMobiBanner
android:layout_width="320dp"
android:layout_height="50dp"
android:id="@+id/banner"
ads:placementId="plid-1431977751489005"
ads:refreshInterval="60"
/>
</LinearLayout>
您可以选择横幅刷新时生效的动画样式。您也可以选择关闭横幅刷新时的任何动画效果。
为此，您可以setAnimationType(InMobiBanner.AnimationType)在获取横幅实例后调用该方法。
默认动画已启用AnimationType.ROTATE_HORIZONTAL_AXIS。如果要关闭此功能，请调用setAnimationType带有AnimationType.ANIMATION_OFF参数的方法。
如果您想监听横幅生命周期中的关键事件，则需要实现该BannerAdListener接口。然后，您可以使用实例setListener(BannerAdListener)上的相应方法来设置此监听器InMobiBanner。每个事件的简要说明如下。
/**

public abstract class BannerAdEventListener {

如果您已不再使用 Banner 对象，只需对其调用 deprecate 方法即可释放资源。这将执行以下操作：
bannerAd.destroy(); // bannerAd is an example instance.
bannerAd.destroy() // bannerAd is an example instance.
