如何使用最新的SDK将comMob Banner添加到getView中-com.google.android.gms.ads

Question

我正在尝试将adMob Banner广告添加到片段之一中用于ListView的getView方法中。 我正在使用最新的adMob SDK（com.google.android.gms.ads。）。

我仅找到使用旧版Google SDK的示例。 如果有人链接到当前版本的Google admob的示例，请告诉我。

仅供参考-我接受了蒂姆的建议。 我从http://jmsliu.com/1482/adding-admob-banner-in-android-listview-header.html找到了完整的代码示例。

我第一次向您展示了它，但是它设置了3个活动。 经过几个小时的测试，我想向您展示我的代码和我当前遇到的错误以及原始代码。 我在整个程序中添加了“ Log.i”，以确定导致异常终止的行。 看来广告返回的是null。 另外，请注意，原始代码版本（在错误部分之后）具有特殊的“ keytwordSet”逻辑。 我无法摆脱语法错误，因此将其从版本中删除。

AdRequest adRequest = new AdRequest(); Set keywordsSet = new HashSet(); keywordsSet.add("game"); keywordsSet.add("dating"); keywordsSet.add("money"); keywordsSet.add("girl"); adRequest.addKeywords(keywordsSet); adView.loadAd(adRequest);
