Try this way,

public class tab2 extends Fragment {

WebView webView ;
 ProgressBar progressBar;

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

        View view = inflater.inflate(R.layout.tab2, container, false);



        webView = (WebView) view.findViewById(R.id.webview1);
        progressBar = (ProgressBar)view.findViewById(R.id.progressBar1);
        webView.setWebViewClient(new myWebClient());
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl("http://google.com");

        return view;
  }

public class myWebClient extends WebViewClient
    {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            // TODO Auto-generated method stub
                progressBar.setVisibility(View.VISIBLE);
            view.loadUrl(url);
            return true;

        }

        @Override
        public void onPageFinished(WebView view, String url) {
            // TODO Auto-generated method stub
            super.onPageFinished(view, url);

            progressBar.setVisibility(View.GONE);
        }
    }
