Question

我是php / web / mysql / css / js开发人员，并且是java和android的新手。我的第一个网络视图的工作原理很吸引人，但是我无法弄清楚为什么我的admob根本不起作用。到目前为止，我从这里和www尝试了一些教程，但没有成功。我确定你们中的任何极客都会立即发现问题，因此在此先感谢。将在下面的主题中添加相关代码，请让我知道这边有什么问题。如果您需要更多资源，我也可以在此处添加。

那是我到目前为止所拥有的：

Answer 1

像这样更改您的xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <WebView
        android:id="@+id/activity_main_webview"
        android:layout_above="@id/adView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        ads:adSize="BANNER"
        ads:adUnitId="@string/footer_ad_id"
        android:background="#000000"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" 
        android:layout_alignParentBottom="true"/>
<!--
   In the above adView, change height from wrap_content to some particular 
   size, 30dp, for example to see if you get the desired layout. 
   Even if the ad doesn't load, you know the layout is right because there
   will be a black color where the ad should load.
-->

</RelativeLayout>

Answer 2

You need to change your xml file like below:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    xmlns:ads="http://schemas.android.com/apk/res-auto">

    <WebView
        android:id="@+id/activity_main_webview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"

        />

    <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ads:adSize="BANNER"
        ads:adUnitId="@string/footer_ad_id"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true">
    </com.google.android.gms.ads.AdView>


</LinearLayout>
