从webview中删除特定元素

我正在制作一个供个人使用的webview应用程序，但广告太多，所以我决定以这种方式对它们加以修饰。标题现在不可见，但广告仍然可见！禁用javascript删除所有的广告，但我需要验证码图像是可见的，这是唯一可能的JavaScript启用时。从webview中删除特定元素

public class MainActivity extends Activity { 
    private WebView mWebView; 

    // fit on screen 
    private int getScale() { 
     Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)) 
       .getDefaultDisplay(); 
     int width = display.getWidth(); 
     Double val = new Double(width)/new Double(width); 
     val = val * 100d; 
     return val.intValue(); 
    } 

    // fit on screen 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     //mWebView.getSettings().setLoadsImagesAutomatically(false); 
     mWebView = (WebView) findViewById(R.id.webView1); 
     mWebView.getSettings().setJavaScriptEnabled(true); 
     mWebView.setWebViewClient(new MyWebViewClient()); 
     // mWebView.loadUrl("http://www.afreesms.com.prx2.unblocksit.es/freesms/"); 
     mWebView.loadUrl("http://www.afreesms.com/freesms/"); 
     mWebView.setPadding(0, 0, 0, 0);// fit on screen 
     mWebView.setInitialScale(getScale());// fit on screen 

     // zoom support 
     mWebView.getSettings().setSupportZoom(true); 
     mWebView.getSettings().setBuiltInZoomControls(true); 
     if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) { 
      // Use the API 11+ calls to disable the controls 
      // Use a seperate class to obtain 1.6 compatibility 
      new Runnable() { 
       public void run() { 
        mWebView.getSettings().setDisplayZoomControls(false); 
       } 
      }.run(); 
     } else { 
      ZoomButtonsController zoom_controll = null; 
      try { 
       zoom_controll = (ZoomButtonsController) mWebView.getClass() 
         .getMethod("getZoomButtonsController") 
         .invoke(mWebView, null); 
      } catch (IllegalAccessException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch (IllegalArgumentException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch (InvocationTargetException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } catch (NoSuchMethodException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      zoom_controll.getContainer().setVisibility(View.GONE); 
     } 
     // zoom support 

    } 

    private class MyWebViewClient extends WebViewClient { 

     public void onLoadResource(WebView view, String url) { 
      super.onLoadResource(view, url); 
      // Removes element which id = 'mastHead' 
      view.loadUrl("javascript:(function() { " 
        + "(elem = document.getElementById('header')).parentNode.removeChild(elem); " 
        + "})()"); 
     } 

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

     @Override 
     // Loading Spinner and status 
     public void onPageStarted(WebView view, String url, Bitmap favicon) { 
      super.onPageStarted(view, url, favicon); 
      // 
     } 

     @Override 
     public void onPageFinished(WebView view, String url) { 
      // 
     } 
    };

是否在http://www.afreesms.com/freesms/上启用了广告？如果是，那么你不能从应用程序中删除它们，因为它直接从网站加载数据。
