Java 碎片状Admob

我使用appcompact创建了一个空项目，并尝试向其中添加AdMob块

fragment_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    tools:context="com.example.testadmobv.MainActivity$PlaceholderFragment" >
   <LinearLayout    
        android:id="@+id/layout_admob"

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >
    </LinearLayout>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

</RelativeLayout>

在“adView=new adView（getActivity（））”行中，“error”Unreachable code“

您有

View rootView = inflater.inflate(R.layout.fragment_main, container,
                false);
return rootView; // remove this
adView = new AdView(getActivity()); // this is unreachable coz you have return above.

---

onCreateView

末尾的返回很好

这就是答案。。。您将在findViewById之前写入root。就这些

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

---

谢谢，搞笑发生了，没有看到“回归”(

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