崩潰片段

Question

我正在製作一個使用滑動菜單片段的webview瀏覽器。當我打開這個片段時，應用程序崩潰。我是新來的碎片，所以我很抱歉，如果這是不懂的。如果還有其他事情可以幫助解決這個問題，那就問問。

下面是片段類

public class WhatsHotFragment extends Fragment { 

public WhatsHotFragment(){} 

WebView WebViewB; 
ProgressBar Pbar6; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 

    View rootView = inflater.inflate(R.layout.fragment_whats_hot, container, false); 

    Pbar6 = (ProgressBar) getView().findViewById(R.id.progBar6); 
    WebViewB = (WebView) getView().findViewById(R.id.wvBrowserAesir); 

    WebSettings webSettings = WebViewB.getSettings(); 
    webSettings.setJavaScriptEnabled(true); 
    WebViewB.getSettings().setLoadWithOverviewMode(true); 
    WebViewB.getSettings().setUseWideViewPort(true); 
    WebViewB.getSettings().setBuiltInZoomControls(true); 
    WebViewB.getSettings().setAllowFileAccess(true); 

    WebViewB.setWebViewClient(new InsideWebViewClient()); 
    WebViewB.setWebChromeClient(new WebChromeClient() { 
     public void onProgressChanged(WebView view, int progress) 
      { 
      if(progress < 100 && Pbar6.getVisibility() == ProgressBar.VISIBLE){ 
       Pbar6.setVisibility(ProgressBar.VISIBLE); 
      } 
      Pbar6.setProgress(progress); 
      if(progress == 100) { 
       Pbar6.setVisibility(ProgressBar.VISIBLE); 
      } 
      } 
     }); 
     { 
      WebViewB.loadUrl("http://www.google.com"); 
     } 


    return rootView; 
} 
} 

提前感謝！

更改爲

Pbar6 = (ProgressBar) rootView.findViewById(R.id.progBar6); 
    WebViewB = (WebView) rootView.findViewById(R.id.wvBrowserAesir); 

您還可以使用getView().findViewById在onActivityCreated初始化你的看法。
