第一次调用WebViewClient时页面加载速度较慢

以下是我的WebViewClient代码。我通过点击一个按钮来调用这个类。第一次调用WebViewClient时页面加载速度较慢

public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     //this.getWindow().requestFeature(Window.FEATURE_PROGRESS); 
     setContentView(R.layout.webview); 

     webView = (WebView) findViewById(R.id.webView1); 
     webView.getSettings().setJavaScriptEnabled(true); 
     webView.setWebChromeClient(new WebChromeClient() { 
      public void onProgressChanged(WebView view, int progress) { 
       activity.setTitle("Loading..."); 
       activity.setProgress(progress * 100); 

       if (progress == 100) 
        activity.setTitle(R.string.app_name); 
      } 
     }); 

     webView.setWebViewClient(new WebViewClient() { 
      @Override 
      public void onReceivedError(WebView view, int errorCode, 
        String description, String failingUrl) { 
       // Handle the error 
      } 

      @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
       view.loadUrl(url); 
       return true; 
      } 
     }); 

     webView.loadUrl("http://mylink.com"); 
     // String customHtml = 
     // "<html><body><h1>Hello, WebView</h1></body></html>"; 
     // webView.loadData(customHtml, "text/html", "UTF-8"); 

    } 

}
