Android 缺少必需的 XML 属性“adSize”

Required XML attribute "adSize" was missing

提问by Glork

I get a "Required XML attribute "adSize" was missing" when I launch my app. This is written on the screen of my smartphone instead of my banner.

当我启动我的应用程序时，我得到一个“必需的 XML 属性“adSize”丢失”。这是写在我智能手机的屏幕上，而不是我的横幅上。

I tried the different solutions founded on stack (like xmlns:ads="http://schemas.android.com/apk/res-auto"instead of xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads"or instead of xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads") but it doesn't work.

我尝试了基于堆栈的不同解决方案（例如xmlns:ads="http://schemas.android.com/apk/res-auto"代替xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads"或代替xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"），但它不起作用。

Here's my java code (a simple Hello World just to try to implement a banner):

这是我的 java 代码（一个简单的 Hello World 只是为了尝试实现一个横幅）：

package com.example.publicite;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
}

Here's my xml file:

这是我的 xml 文件：

<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />

<com.google.android.gms.ads.AdView
    xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads"
    android:id="@+id/adView"
    android:layout_width="fill_parent"

    ads:adSize="BANNER"
    ads:adUnitId="MyAdUnitId"
    ads:loadAdOnCreate="true"

<Button
    android:id="@+id/votrescore"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="..." />

</RelativeLayout>

and here's my manifest:

这是我的清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</application>

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

 </manifest>

I use the google play service lib.

我使用谷歌播放服务库。

Try changing your declaration this way:

尝试以这种方式更改您的声明：

<com.google.android.gms.ads.AdView
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/adView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    ads:adUnitId="YOUR_AD_UNIT_ID"
    ads:adSize="BANNER"/>

---- EDIT ----

You can also try to do it programmatically. Simply, instead of an AdViewlayout item, define a LinearLayoutand by code do something like this:

您也可以尝试以编程方式进行。简单地说，而不是一个AdView布局项，定义一个LinearLayout和通过代码做这样的事情：

final AdView adView = new AdView(getActivity());
adView.setAdUnitId("YourId");
adView.setAdSize(AdSize.BANNER);

final LinearLayout adLinLay = (LinearLayout) view.findViewById(R.id.your_defined_linearlayout);
adLinLay.addView(adView);

final AdRequest.Builder adReq = new AdRequest.Builder();
final AdRequest adRequest = adReq.build();
adView.loadAd(adRequest);

回答by joselquin

I had the same problem and I corrected it with the xmlns labels. I put two "xmlns:ads" labels (one for "res-auto" in the AdView and other for "tools" in the parent layout). I had to use two labels for "res auto", one with xmlns:app in the FloatingActionButton and other with xmlns:ads in the AdView:

我遇到了同样的问题，我用 xmlns 标签更正了它。我放置了两个“xmlns:ads”标签（一个用于 AdView 中的“res-auto”，另一个用于父布局中的“工具”）。我不得不为“res auto”使用两个标签，一个在 FloatingActionButton 中使用 xmlns:app，另一个在 AdView 中使用 xmlns:ads：

        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        />

    <android.support.design.widget.CoordinatorLayout

I faced the same error. but I couldn't fix it with the pinned answer. I changed the xml to be like this.

我遇到了同样的错误。但我无法用固定答案修复它。我将xml更改为这样。

<com.google.android.gms.ads.AdView
  xmlns:ads="http://schemas.android.com/apk/res-auto"
  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 = "ca-app-pub-3940256099942544/6300978111">
</com.google.android.gms.ads.AdView>

The main changes are: xmlns:ads="http://schemas.android.com/apk/res-auto"and ads:adSize="BANNER". I recorded my laptop screen while solving this issue. So If you like visual illustrations, you can see the video on YouTube.

主要变化是： xmlns:ads="http://schemas.android.com/apk/res-auto"和 ads:adSize="BANNER"。我在解决这个问题时记录了我的笔记本电脑屏幕。所以如果你喜欢视觉插图，你可以在 YouTube 上观看视频。

Add this in android manifest:

在 android manifest 中添加这个：

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

    <activity
        android:name="com.google.android.gms.ads.AdActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
        android:theme="@android:style/Theme.Translucent" />

That solved my problem, I hope it will solve yours.
