java - InterstitialAd的构造函数

Question

我正在尝试将 InterstitialAd 集成到我的应用程序 fragment 之一中。我正在关注它的官方网站，但如果我输入如下代码，它会给我错误，如 The constructor InterstitialAd(AuthorListFragment) is undefined

The constructor InterstitialAd(MyListFragment) is undefined

我的完整代码如下。

public View onCreateView(LayoutInflater inflater, ViewGroup group,Bundle savedState){
    super.onCreateView(inflater,group,savedState);

    return inflater.inflate(R.layout.fragment_home,null);


    mInterstitialAd = new InterstitialAd(this);
    mInterstitialAd.setAdUnitId("ca-app-pub-3940256099942544/1033173712");
    final AdRequest adRequest = new AdRequest.Builder()
    .addTestDevice("7C77ADF1D83FA8B87C0481D6748FA4DB")
    .build();
    mInterstitialAd.loadAd(adRequest);

    mInterstitialAd.setAdListener(new AdListener() {
        @Override
        public void onAdClosed() {
          AdRequest adRequest = new AdRequest.Builder()
          .addTestDevice("7C77ADF1D83FA8B87C0481D6748FA4DB")
          .build();
          mInterstitialAd.loadAd(adRequest);
        }
    });
}

我缺少什么？

感谢您的帮助:)

public View onCreateView(LayoutInflater inflater, ViewGroup group,Bundle savedState){
    super.onCreateView(inflater,group,savedState);

   //return inflater.inflate(R.layout.fragment_home,null);
   // take this to end

    mInterstitialAd = new InterstitialAd(getActivity());
    mInterstitialAd.setAdUnitId("ca-app-pub-3940256099942544/1033173712");
    final AdRequest adRequest = new AdRequest.Builder()
    .addTestDevice("7C77ADF1D83FA8B87C0481D6748FA4DB")
    .build();
    mInterstitialAd.loadAd(adRequest);

    mInterstitialAd.setAdListener(new AdListener() {
        @Override
        public void onAdClosed() {
          AdRequest adRequest = new AdRequest.Builder()
          .addTestDevice("7C77ADF1D83FA8B87C0481D6748FA4DB")
          .build();
          mInterstitialAd.loadAd(adRequest);
        }
    });
    return inflater.inflate(R.layout.fragment_home,null);

}
