..コードの下にこれを試し

private class MyBrowser extends WebViewClient { 
      @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       view.loadUrl(url); 
       return true; 
      } 

      @Override 
      public void onPageStarted(WebView view, String url, Bitmap favicon) { 
       super.onPageStarted(view, url, favicon); 
       progressDialog_webview = new ProgressDialog(Yourclassname.this); 
       progressDialog_webview.setMessage("Please wait ..."); 
       progressDialog_webview.show(); 
      } 

      @Override 
      public void onPageFinished(WebView view, String url) { 
       super.onPageFinished(view, url); 
       if (progressDialog_webview != null) { 
        progressDialog_webview.dismiss(); 
       } 
      } 

     }
