在 Android 工作室中添加横幅广告 Admob

Question

请帮助我。当我向程序添加 admob 时，此代码不起作用。可能是我用错了方式。请建议我使用横幅广告编辑代码。我应该在哪里添加广告代码？调试中没有错误，但应用程序未运行无法加载应用程序。谢谢。

Answer 1

你只需要在你的活动中有这样的东西：

 AdView adView = (AdView)findViewById(R.id.adView);
 AdRequest adRequest = new AdRequest.Builder().build();
 adView.loadAd(adRequest);     

带有您的添加的视图：

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

您的 Android 清单中的广告活动.xml ：

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

并且不要忘记您的AndroidManifest中的权限.xml ：

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

将您的广告单元 ID 存储在字符串.xml文件中。以下 ID 仅用于测试，请务必在发布应用之前进行更改。

<?xml version="1.0" encoding="utf-8"?>
<resources>    
    <string name="banner_ad_unit_id">ca-app-pub-3940256099942544/6300978111</string>
</resources>

检查所有这些，它应该可以工作。

Answer 2

mAdView.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
    // Code to be executed when an ad finishes loading.
}
@Override
public void onAdFailedToLoad(int errorCode) {
Log.d("errorcode",""+errorCode);
    // Code to be executed when an ad request fails.
}
@Override
public void onAdOpened() {
    // Code to be executed when an ad opens an overlay that
    // covers the screen.
}
@Override
public void onAdLeftApplication() {
    // Code to be executed when the user has left the app.
}
@Override
public void onAdClosed() {
    // Code to be executed when when the user is about to return
    // to the app after tapping on an ad.
}
});

将此代码放入 onCreate（）、ad listener 并检查错误代码比说我错误代码我给你解决方案。

Answer 3

您应该重写生命周期方法并在其中进行资源清理。

@Override
public void onPause() {
    if (mAdView != null) {
        mAdView.pause();
    }
    super.onPause();
}
@Override
public void onResume() {
    super.onResume();
    if (mAdView != null) {
        mAdView.resume();
    }
}
@Override
public void onDestroy() {
    if (mAdView != null) {
        mAdView.destroy();
    }
    super.onDestroy();
