<？xml version =1.0encoding =UTF-8？>

 xmlns：tools =http://schemas.android.com/tools
 android：layout_height =match_parent

<！ - 示例AdMob App ID：已编辑ID  - > 
< meta-data

 android：layout_alignParentBottom =true
 ads：adSize =BANNER
 ads ：adUnitId =已编辑ID
 com.google.android.gms.ads.AdView /> 
 
 
< / RelativeLayout> 

我的尝试：

我不知道怎么解决这个问题，它在com.google.android.gms.ads上说= .AdView /> 

解决方案

查看您发布的XML的倒数第二行。

 com.google.android.gms.ads.AdView 

这不是有效的属性。事实上，除了/>之外，看起来该行甚至不应该存在。它的一部分。



XML属性的格式始终为 name = value 。

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

    <!-- Sample AdMob App ID: Edited out ID -->
    <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="[ADMOB_APP_ID]"/>


    <com.google.android.gms.ads.AdView
    android:id="@+id/adview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_alignParentBottom="true"
    ads:adSize="BANNER"
    ads:adUnitId="Edited out ID"
    com.google.android.gms.ads.AdView/>


</RelativeLayout>

What I have tried:

I am at a loss how to fix this, it says "=" expected at com.google.android.gms.ads.AdView/>

解决方案

Look at the second to last line of that XML you posted.

com.google.android.gms.ads.AdView

That's not a valid attribute. In fact, it looks like that line should not even be there, except for the "/>" part of it.

XML attributes are always of the format name="value".
