        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_main, container, false);
            return rootView;
        }
    }
    
    class webViewClient extends WebViewClient{ 

        //重写shouldOverrideUrlLoading方法,使点击链接后不使用其他的浏览器打开。 

     @Override 

     public boolean shouldOverrideUrlLoading(WebView view, String url) { 

         view.loadUrl(url); 

         //如果不需要其他对点击链接事件的处理返回true,否则返回false 

         return true; 

     } 

         

    } 

}

采用webview,并且处理了禁止了页面横条的效果。
