admob - 看不到广告，但日志显示广告已完成加载

Question

我有以下代码。我看不到任何广告，但在日志消息中我可以看到广告已完成加载。

我所做的就是读取 json 并显示数据。我的布局 xml 中没有任何内容，并且我正在动态创建所有 View 元素......

Answer 1

您可能遇到问题，因为您正在从#onCreate 调用#displayInterstitial。您不应该在加载后立即调用#displayInterstitial。

1. 它可能不起作用(这就是您所看到的
2. 这将使您的 Admob 帐户被禁止。

您应该在应用程序的自然断点处调用#displayInterstitial。
