java - 如何在 Fragment 上初始化 Google AdMob 横幅

Question

我正在尝试编写代码来初始化 Fragment 上的 Google Admobs 横幅。

我读到代码是

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

但是当我在 Fragment 上编写此内容时，Android Studio 无法识别 findViewById

我认为这段代码是针对Activities的，而不是针对Fragments的

我的问题是如何在片段上初始化 Admob 横幅

在片段中使用 getActivity().findViewById()。
