因为 WebView 是一个 AbsoluteLayout,所以您可以像这样定位它的子视图:
    AbsoluteLayout.LayoutParams params = AbsoluteLayout.LayoutParams(width,height,X-position,Y-position);
    adView.setLayoutParams(params);
但是,将 WebView 放在 LinearLayout 中会更容易,因此当您添加广告时,它会自动出现在底部。例如:
    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/main"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical">
        <WebView
            android:id="@+id/webView1"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />
    </LinearLayout>
您的代码必须更改为如下所示:
    private AdView adView;
    adView = new AdView(this, AdSize.BANNER, "my publisher id");
    LinearLayout root = (LinearLayout)findViewById(R.id.main);
    root.addView(adView);
    adView.loadAd(new AdRequest());
另一种选择是在 xml 中包含广告。您可以在 AdMob https://developers.google.com/mobile-ads-sdk/docs/admob/fundamentals#android开发者指南中了解如何执行此操作  。取自网站:
    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
          android:orientation="vertical"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent">
      <!-- WebView goes here -->
      <com.google.ads.AdView android:id="@+id/adView"
                     android:layout_width="wrap_content"
                     android:layout_height="wrap_content"
                     ads:adUnitId="MY_AD_UNIT_ID"
                     ads:adSize="BANNER"
                     ads:testDevices="TEST_EMULATOR, TEST_DEVICE_ID"
                     ads:loadAdOnCreate="true"/>
      </LinearLayout>
