【问题标题】：How to add adMob Banner into getView using the latest SDK - com.google.android.gms.ads如何使用最新的 SDK 将 adMob Banner 添加到 getView - com.google.android.gms.ads
【发布时间】：2014-03-12 23:42:00
【问题描述】：

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

我只找到使用旧版 Google SDK 的示例。如果有人有当前版本的 Google admob 示例的链接，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。

它是我第一次向您展示的不同的，但设置了 3 个活动。经过几个小时的测试，我想我会向您展示我的代码和我目前遇到的错误以及原始代码。我在整个程序中添加了“Log.i”以确定哪一行导致异常结束。广告似乎返回 null。另外，请注意原始版本的代码（在错误部分之后）具有特殊的“keytwordSet”逻辑。我无法摆脱语法错误，所以我从我的版本中删除了它。

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);

【问题讨论】：

标签： java android admob

【解决方案1】：

通过声明同名的局部变量，您似乎在新代码中隐藏了类变量“adView”。由于范围的原因，您将 convertView 设置为全局 adView，它始终为空。只需将“AdView adView =”更改为“adView =”

【讨论】：

哇。就是这样。它在模拟器中工作得很好。现在我需要做的就是将此逻辑添加到我要发布的程序中的列表片段中。感谢您的帮助:)
没有问题。顺便说一句，欢迎来到 Stack Overflow，如果您有需要，请不要忘记选择问题的答案（关闭它）。
现在使用我的 ListFragment ，我尝试在 adView 中设置的活动出现空指针异常错误。您知道在片段中设置广告视图的最佳方式吗？
这可能不是广告浏览问题；它可能是关于使用片段管理您的活动生命周期。不要将成员变量存储在活动中，使用 getActivity() 检索它。您不应该在 Android 中自行管理许多参考资料，因为它们可能会超出您的权限范围。
对主要问题的进一步编辑使其他人难以从中获得有用的信息。最好为单独的主题打开新问题。我的意思是权限：google.com/search?q=define%3Apurview 至于要进行的更改，请执行 'mainActivity = getActivity();'在 onCreateView 中使用它之前 - 不要使用过时的活动参考。
