フラグメントを使用して webView を実装したいのですが、.xml は次のようになります。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<webView
    android:id="@+id/webView01"
    android:layout_width="wrap_content"
    android:layout_height="450dp"/>

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal">

    <webView
        android:id="@+id/webView02"
        android:layout_width="180dp"
        android:layout_height="50dp"
        />
    <webView
        android:id="@+id/webView03"
        android:layout_width="180dp"
        android:layout_height="50dp"/>

</LinearLayout>
</LinearLayout>

そして、私がwebviewを扱う方法は、 public class SelectionFragment extends Fragment{ のようなものです

@Override
public View onCreateView(LayoutInflater inflater,
        ViewGroup container, Bundle savedInstanceState){
    super.onCreateView(inflater,container,savedInstanceState);
    View view =inflater.inflate(R.layout.selected,container,false);
    return view;    
}
    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.activity_main);
    WebView webView1=(WebView) getView().findViewById(R.id.webView01);
    String url="#######";
    String url1="####"; String url2="#######";
    webView1.setWebViewClient(new Callback());
    webView1.loadUrl(url);
    WebView webView2=(WebView)getView().findViewById(R.id.webView02);
    WebView webView3=(WebView)getView().findViewById(R.id.webView03);

    webView2.loadUrl(url1);
    webView3.loadUrl(url2);
     }
     private class Callback extends WebViewClient{
    public boolean shouldOverrideUrlLoading(WebView view, String url){
        return(false);
    }

}

アプリケーションを実行すると、エラーが表示されます

しかし、.xml を変更し、webView を単純な TextView に変更し、webView を処理するコードを削除すると、エラーが修正されました。誰でも私にいくつかのアイデアを提供できますか？

ありがとう
