    Instead of this: 

       mWebView = (WebView) findViewById(R.id.webviewHelp);    
   mWebView.setLayoutParams(new ViewGroup.LayoutParams(100, 200));

    use: 

       mWebView = (WebView) findViewById(R.id.webviewHelp);        
   LayoutParamters lp = mWebView.getLayoutParams();    
   lp.width=100;   
   lp.height=200;   
   mWebView.setLayoutParams(lp);
