Question

我正在制作一个使用滑动菜单片段的webview浏览器。当我打开这个片段时，应用程序崩溃了。我是碎片的新手，所以如果这很不好我就道歉。如果还有什么我可以帮忙解决这个问题，那就问一下。

下面是片段类

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;
}
}

提前致谢！

更改为

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

您还可以使用getView().findViewById中的onActivityCreated初始化您的观看次数。
